The Weather at Guyra NSW
The town of Guyra is
literally at the top of the range near the higher parts of the Northern
Tablelands. In fact the Great Divide runs right through the town itself. The Bureau
of Meteorology weather station is located in the grounds of the Guyra Hospital, elevation 1332 metres.
This station has been in operation since August 1981.
Prior to this the post office operated a weather station from 1911 to 1972 with a number of gaps. Rainfall has been recorded for a longer period starting in 1886 at the post office.
Readings are taken daily at the hospital at the standard observation times of 9am and 3pm.

About Guyra’s Weather
Guyra is the highest town on the Northern Tablelands and as such records the lowest day time temperatures in the region. Overnight temperatures however, particularly in the winter months, are frequently higher than nearby Armidale and Glen Innes. This is because Guyra is at the top of an exposed plateau where the wind may blow all night, whereas Armidale and Glen Innes are in protected valleys where cold air drainage and temperature inversions are common events allowing overnight temperatures to drop to lower levels.
If you want to see snow on the Northern Tablelands, Guyra is the place to be with an average of five snowfalls per year. Most years Guyra manages at least one good snowfall with snow several centimetres deep on the ground, easily enough to build a good sized snow person! During such events the New England Highway is often closed to the north and south of the town for a few hours or maybe a full day.
Guyra's climate can be summed up as mild in summer and cold in winter.
Highest temperature on record: 34.4C* on 3rd January 2014.
Lowest maximum temperature: -0.3C on 3rd July 1984 during particularly heavy snowfalls.
Lowest minimum temperature: -7.8C on 26th June 1971.
* Estimated actual record high: 36C approx. on 15 January 1939 (Armidale’s record high was 39.7C on this day).
The Guyra Post Office was taking temp readings at this time, but unfortunately the daily records are not available.

WARMEST MARCH FOR 17 YEARS - With maximum temperatures averaging 23.0C it was the warmest March since 1998. At this time of year winds are usually mild easteries, but during March a number of troughs over New South Wales caused west and north-westerly winds to prevail drawing in warm air from central Queensland lifting temperatures above normal levels.
HOTTEST MARCH DAY FOR 17 YEARS - 20th March - A very warm north-westerly airstream ahead of a low pressure trough and cold front caused temperatures in northern New South Wales to soar to almost record levels in many areas. Guyra’s maximum of 30.0C was the highest for the month of March since 14th March 1998 when 30.2C was recorded. It was also the hottest day since 23rd November last year when it reached 33.2C.
BEN LOMOND HAILSTORM - 19th January - A severe hailstorm struck the Ben Lomond area north of Guyra in the afternoon with hailstones up to 2.5 cm diameter. Details and photographs courtesy of the Guyra Argus here.

2014 RAINFALL TOTAL: 665 mm - 214 mm less than the long term average.
2014 WARMEST YEAR ON RECORD - 2014 was Guyra’s warmest year on record. The average temperature for the year of 13.1C was the highest on record from 74 years of complete temperature records available. The previous highest was 2009 (12.9C). Contributing factors were unusually warm day temperatures in January, February, October and November.
WARMEST NOVEMBER ON RECORD - Both the average maximum temperature of 25.5C and average minimum of 11.7C were the highest on record for Guyra for the month of November. Temperatures reached or exceeded 28C on eight days of the month. A number of days with very warm north-westerly winds associated with trough systems combined with sunnier than normal conditions were the reasons for the unusually warm month.
Temperature records for Guyra commenced in 1911 with a number of gaps up until 1981. Only monthly averages available from 1911 to 1965.
HOTTEST NOVEMBER DAYS ON RECORD - 15th & 23rd November - Hot north-westerly winds ahead of a low pressure trough caused temperatures to soar to near record levels for November on the 15th in northern New South Wales. Guyra’s maximum of 32.0C was the highest on record for November (daily records available from 1965). The previous highest November maximum was 31.6C on 20th November 2009.
Eight days later this record was broken again as hot north-westerly winds associated with another trough resulted in a maximum of 33.2C on 23rd November 2014.
DRIEST OCTOBER FOR 63 YEARS - The rainfall total of just 13.4 mm for the month was the lowest for the month of October since 1951 when 9.4 mm was recorded.
WARMEST OCTOBER FOR 74 YEARS - With an average maximum temperature of 21.5C for the month, October 2014 was the warmest October since 1940 (22.2).
HOTTEST OCTOBER DAY ON RECORD - 26th October - 29.3C - A low pressure trough over inland New South Wales directed very warm north-westerly winds over most of the state with Guyra recording a maximum temperature of 29.3C. This was the Guyra’s hottest October day on record (from 41 years of temperature records available). The previous highest was 28.5C on 19th October 2002. It was almost as hot again the following day with a maximum of 29.0C on the 27th.
OCTOBER COLD SNAP - 14th October - A cold front passed through the Northern Tablelands in the early morning bringing cold winds, showers and thunderstorms. In Guyra in the late afternoon very cold air following the front delivered a shower of soft hail or ice pellets (small pellets of ice around 3 to 5 mm diameter, sometimes referred to as sago snow) which partially whitened the ground at around 5.30pm. The maximum temperature on the day was 11.6C, and rain from the event totalled 12.8 mm. This was not classified as a “snow day” as no snowflakes were observed.
SPRING SNOWFALL - 2nd/3rd September - A cold front passed through the Northern Tablelands during the afternoon of the 2nd with strong gusty winds and several showers of soft hail (sometimes referred to as sleet or sago snow) during the afternoon and evening. In the early hours of the 3rd there were light snow showers with a patchy cover on the ground at sunrise. It melted soon after 9am. Light snow also fell around Ben Lomond, Black Mountain and Ebor with heavier falls further south around Hanging Rock.
JULY SNOW - 18th July - As an intense cold front swept through New South Wales in the early hours, snow fell in a wide area of the Northern Tablelands including Niangala, Walcha, Uralla, Armidale, Ebor and Ben Lomond. In Guyra there were early morning snow showers with snow settling about 3 cms deep on the ground at 9am. It had melted by 12 noon. Winds during the day were very cold south-westerlies. The maximum temperature was just 2.5C, but the wind chill temperature remained between -6C and -10C throughout the day in the strong winds. This was Guyra’s coldest day since 9th July 2008 (1.8C max).
LIGHT SNOWFALLS - 30th June - An upper level cold pool combined with moist surface westerly winds generated snow showers over the higher parts of the Northern Tablelands. In Guyra light snow fell in the early hours with a patchy cover on the ground until around 9am when it melted. There were further brief snow showers between 10am and noon, but did not settle. Conditions were very cold during the day with a maximum of just 3.8C and a 3pm wind chill temperature of -4C in the south-westerly winds. Light snow also fell around Black Mountain and Ben Lomond.
MAY SNOWFALLS - 3rd/4th May - Temperatures plunged to mid-winter levels on the 3rd as a severe cold front passed through northern New South Wales bringing showers, strong winds, low temperatures and some light snowfalls to higher parts of the Northern Tablelands. The Guyra/Black Mountain/Ben Lomond areas all received a few light snow and sleet showers. Walcha had at least one snow shower and even Armidale saw a few snowflakes.
In Guyra there were a few light snow showers on the evening of the 3rd and early in the morning of the 4th, but barely settled on the ground. Maximum temperature on the 3rd was just 4.6C, but the strong winds caused the wind chill temperature to be around -5C to -10C for most of the day. Minimum on the 4th was -1.1C, maximum on the 4th was 4.1C - coldest May day since 30th May 2000 (3.5C).
SUMMER OF 2013/14 DRIEST ON RECORD - The rainfall total for the three summer months of just 74.7 mm was the lowest on record (125 years of records).
December recorded 27.6 mm, January was the lowest with 8.9 mm, and February totaled 38.2 mm.
DRIEST JANUARY FOR 33 YEARS - The month total of just 8.9 mm was the lowest for the month of January since 1981 (4.4 mm), and was the lowest for any month since August 2008 (3.6 mm).
Only 36.5 mm was recorded over December 2013-January 2014, driest for these two months on record (records commenced in 1886 with a few gaps).
HOTTEST JANUARY FOR 11 YEARS - Day temperatures during the month averaged 26.2C which was the highest since January 2003 (26.2C). Temperatures reached or exceeded 28C on 11 days with the highest being 34.4C on the 3rd - see below.
HOTTEST DAY FOR 62 YEARS: 34.4C - 3rd January - A low pressure trough over inland New South Wales directed very hot north-westerly winds originating from central Australia over the north of the state. As a result many areas recorded their hottest day on record. In Guyra the maximum was 34.4C, the highest recorded at the present weather station site, and the highest since 7th February 1952 (34.5C).

2013 MONTHLY STATISTICS TABLE here.
2013 RAINFALL TOTAL: 754 mm - 124 mm less than the long term average.
BEN LOMOND TORNADO - 23rd November - A severe thunderstorm north of Guyra generated one or more tornadoes at around 4pm. A farmhouse at Tenterden, north-west of Guyra, was destroyed and other nearby buildings were damaged, probably by a tornado which apparently moved in an easterly direction towards Ben Lomond village. More than one tornado developed in the Ben Lomond area, but all were shorted-lived according to this report by storm chasers Michael Bath and Jason Alexander: Ben Lomond tornado report.
RECORD SEPTEMBER WARMTH - The average maximum temperature for the month of 19.3C made it the warmest September on record (from 78 years of records going back to 1911, but with a number of gaps). Also the maximum of 26.0C on Thursday 26th was the highest on record for September. (The previous highest was 25.0C on 29/9/2000 & 25/9/2002.)
The unseasonably warm conditions were caused by a number of troughs moving through New South Wales generating north-westerly winds drawing in very dry warm air from the centre of Australia.
AUGUST COLD SNAP - 8th August - A severe cold front passing through northern New South Wales brought strong winds and low temperatures to Guyra. The maximum temperature was 6.7C but the winds, which gusted to in excess of 50 km per hour at times, made it feel much colder. The 3pm temperature was 3.4C with a wind chill temperature of around -7C. A few tiny flakes of snow (snow grains) were observed during the afternoon, but were insufficient to classify the day as a “snow day”. There was a light snowfall at Walcha during the morning.
FIRST SNOW FOR 2013 - 25th June - Low temperatures, showers and snow occurred along the Northern Tablelands during the morning. An upper level cold pool combined with showers being pushed northwards from a low pressure system near Sydney produced the very cold conditions. Light snow fell and settled on the ground in the Guyra/Black Mountain/Ben Lomond area, and further east around Ebor. In Guyra the snow started at around 3am, lasting for about two hours and settling on the ground about a centimetre deep. Most of it had melted by 9am. There were a few very light showers of snow mixed with rain (sleet) during the morning. The maximum temperature was 4.1C with the 3pm temp at 2.6C.
TEMPERATURE ALMOST REACHES RECORD HIGH - 12th January - Hot north-westerly winds brought unusually high temperatures to the Northern Tablelands. Guyra’s maximum for the day of 32.5C was just 0.3C below the all time record high of 32.8C on 31st January 2003 (records from 1965).
GUYRA HOTTER THAN ARMIDALE - 10th January - Under rather unusual conditions Guyra was three degrees hotter than Armidale with a maximum temperature of 30.0C. Armidale’s maximum was 27.0C. A trough line over the Northern Tablelands allowed hot north-westerly winds to blow over Guyra while Armidale was under the influence of cooler easterly winds resulting in an interesting reversal of temperatures between the two locations.

2012 MONTHLY STATISTICS TABLE here.
2012 RAINFALL TOTAL: 874 mm - 6 mm less than the long term average.
HOTTEST OCTOBER DAY FOR 10 YEARS - 26.8C - Saturday 20th October - Very warm air being drawn in from the centre of the continent by a trough created windy and hot summery conditions over northern New South Wales. Temperatures reached the high thirties over parts of the inland and north coast. With maximum of 26.8C it was Guyra’s hottest day since 8th January this year (27.0C), and was the hottest for the month of October for ten years since 19th October 2002 (28.5C).
SPRING SNOWFALLS - 12th October - A cold snap brought moderate to heavy snowfalls to Guyra and surrounding areas with snow falling from shortly after midnight intermittently through to 9.30am The heaviest falls were between around 4am and 9am. At 9am the snow was 17 cms deep on the ground before it gradually started to melt at around 11am.
Temperatures were very low during the day with a maximum of just 4.0 C. Strong westerly winds made it feel much colder with a 3pm wind chill temperature of -8C. This was Guyra’s coldest October day on record (38 years of records). The previous lowest was 7.2C on 6th October 1983. It was claimed by many residents to be the heaviest Guyra snowfall for at least 20 years. Temperatures were low enough to allow some of the larger ‘snowpersons’ in a number of front yards to survive overnight into the following day.
The snowy conditions were caused by cold
surface temperatures following the passage of a trough, enhanced by an upper
level cold pool, and moisture being added to the system by a low pressure
system off the NSW coast. It also snowed in Tenterfield
along with a few light falls in southern Queensland around Stanthorpe.
NORTHERN TABLELANDS SNOW - 9th-11th August - A cold front which passed through the region on Thursday 9th, and an upper level pool of cold air, brought showers and cold winds along with light snowfalls to some parts of the Northern Tablelands on Friday 10th and early Saturday 11th. There was no snow in Guyra apart from a shower of ice pellets (also referred to as sago snow or soft hail) late on Thursday evening. Light snow fell in Walcha in the early hours of Friday morning, and there were further snow showers south of Walcha late on Friday night and early Saturday morning. At this time snow also fell at Ebor and Point Lookout to the east of Armidale with a light cover on the ground. Guyra’s maximum temperature on Friday 10th was 6.3C with strong south-westerly winds dropping the wind chill temperature well below zero.
UNEXPECTED AUGUST SNOWFALL - 1st August - An upper level pool of cold air over the eastern half of New South Wales contributed to some unexpected snowfalls around Black Mountain and Guyra in the evening. A series of four showers moved across the Northern Tablelands from the south-west between Armidale and Guyra between around 9.30 and 10.30pm. With surface temperatures between 1 and 3 degrees the showers arrived as snow settling on the ground to some extent around Black Mountain and to a lesser extent in Guyra. The sky cleared at around 11pm allowing the temperature to drop well below freezing which resulted in a combination of frost and snow on the ground in Guyra the following morning, 2nd August. Because of ice and snow on the road the New England Highway at the Devil’s Pinch south of Guyra was closed overnight from around 11pm to 9am. This was an unusual event with snow followed by clear skies and severe frost. Also the showers were confined to a very localized area. Guyra’s minimum temperature on 2nd August was -4.6C, Armidale city -5.0C.
LIGHT SNOWFALLS - 28th July - Light showers of snow fell in Guyra early in the morning. It started around 6am and snowed intermittently until just before 9am. There was a very light cover on the ground at 6.30am. A surface trough and upper level cold air brought the unexpected snow. The maximum temperature for the day was 6.3C with the wind chill keeping the temperature around 1C or less.
JULY RAIN EVENT - 12th to 14th July - A slowing moving low pressure trough passed through New South Wales generating moderate to heavy falls in the north of the state. In Guyra the rainfall total for the four days was 91.0 mm which was the heaviest for eight months. The rain cleared in the early hours of the 15th.
Daily totals were: 17.0 mm to 9am on Thurs 12th, 45.0 mm to 9am on Fri 13th, 27.0 mm to 9am on Sat 14th, 2.0 mm to 9am on Sun 15th
FIRST SNOWFALLS IN 2012 - 5th June - An upper level pool of cold air passed over the Northern Tablelands bringing light snowfalls to the higher areas including Guyra, Black Mountain and Ben Lomond. These falls were intermittent and light, and did not settle on the ground apart from a brief shower of sago snow at around 4pm. Maximum temperature was just 3.1C with wind chill temperatures well below zero throughout the day. This was Guyra’s coldest day since 9th July 2008 (1.8C).
SUMMER OF 2011/12 COOLEST FOR 28 YEARS - Over the three summer months of December, January and February the average maximum temperature was 21.0C, the lowest since 1984. The average maximum temp in December was the lowest on record for December, and in January it was the lowest since 1989.
