July 2020 – Warm & dry

Warm summer-like weather continued throughout July after finally getting started in mid-June across New Brunswick.

Several heat warnings were issued with daytime highs reaching 30°C or more on eight days – the normal is two.

The overall average may have been even higher for Greater Moncton had it not been for cool overnight lows early in the month.

July 2020 still falls a bit short of the very warm July 2018 which reached 21.4°C.

The drought worsened and although rainfall was higher compared to June it was still 25 percent below normal.

June 2020 – Suddenly it’s hot!

The first half of June was cold and dry similar to May and April.

But by mid-month, after struggling to reach the 20s, temperatures suddenly began climbing into the 30s.

On 19 June, Greater Moncton hit a sizzling 35.6°C (humidex 40) which is the hottest June temperature in recorded history.

The thermometer climbed above 30°C six times and the average is only once.

Before the heat arrived, a light frost occurred on 10 June which damaged some sensitive crops like strawberries.

Farmers and gardeners also lamented a lack of rain with only one-third of the normal monthly amount recorded.

Scattered frost!

A clear sky and a cool air mass overnight brought scattered frost to parts of the Maritimes.

The average last spring frost (0°C) in Moncton is 22 May.

The temperature dropped to -0.6°C at the Greater Moncton Airport in Dieppe and it remained near freezing for about two hours.

Further north in Kouchibouguac, the thermometer fell to -2.0°C and stayed below freezing for several hours.

Farmers are reporting minor damage to sensitive crops such as strawberries and blueberries but nothing to the extent of a killing frost in June 2018.

Environment Canada data shows a 10% chance of falling to 0°C or lower after 08 June – so it looks like we beat the odds.

May 2020 – Cool and dry

For the last few years, May in Southeast New Brunswick has been colder than normal and this year was no exception.

A new record high was set during a mini heat wave at month’s end which was enough to boost temperatures to just slightly below average.

Snow fell as late as the 12th and rain was scant which led to a dry month overall.

Frost was recorded on the 24th which is close to the last average date in Greater Moncton – if it is the last frost of spring.

Signs of spring were extremely rare in April with frigid overnight lows in Greater Moncton making it feel like a continuation of March.

Any warmth came in short spurts with only 11 days above 10°C and some nights sank as low as -5°C right up to the end of the month.

Like the previous month, April was also quite dry with both rainfall and snowfall amounts well below average.

Much less rain and snow fell in Greater Moncton during March even though precipitation was recorded on 23 days.

Only 10 mm of rain and 32 cm of snow fell with the normals being 49 mm and 65 cm respectively.

Warm daytime highs were scarce – the thermometer failed to reach 10°C – but temperatures were actually slightly above average overall.

The coldest weather occurred during the first few days of spring with a minimum of -13.8°C on 23 March.

Meteorological winter in Greater Moncton covering the months of December, January and February proved to be almost two degrees above normal compared to the 30-year average.

The warmest temperatures were recorded in December while frigid weather in February saw the coldest low in five years.

Precipitation was about 25 percent below normal with little snow in December and barely any rain in February.

January 2020 – Warmer than normal

Glancing at the data for January 2020, one would think it was as cold if not colder than normal in Southeast New Brunswick.

The thermometer sank below -10°C on sixteen days while four of those days dropped to -20°C or lower during the month.

Despite the frigid weather, January was in fact almost three degrees above normal in Greater Moncton.

Despite two major snowfalls (including one event near 30 cm) and some rainfall, precipitation was close to the thirty-year average.

Coldest, snowiest yet this winter

Snow covered steps in NE Moncton, 19 Jan 2020 (Dearing)

On the heels of the coldest weather so far this winter in Greater Moncton with lows of -21°C comes the heaviest snowfall to date.

A Colorado Low arrived in the Maritimes on Sunday after delivering a blow to the middle of the continent including Ontario and Quebec.

Since it was already very cold across Southern New Brunswick, the snow that fell was light and dry – unlike so-called “heart attack” snow which is heavy and wet.

Snowfall totals (in cm):

  • Minto area  31
  • Greater Moncton Airport  25
  • Fredericton area  16
  • Saint John Airport  13
  • Miramichi  10
  • Bathurst  4

Year in Review 2019

YQM 2019
Most major centres across Southern Canada were slightly colder than normal in 2019 with only the Arctic region posting above average values.

Greater Moncton was no exception at 0.1 degree below normal which was in contrast to 2018 which was 0.4 degrees above normal.

Based on the thirty year period from 1981-2010, Moncton had more hot days and fewer frigid days in 2019 but other categories were close to average.

Rainfall was above normal for Southeast New Brunswick while less snowfall was recorded for the year.
