After taking a look at the past seven growing seasons in Greater Moncton including 2019, the last freezing temperature in Greater Moncton in the spring has been recorded from a month-long period from early May to early June.
Meantime in the fall, the first freezing temperature has been recorded from a month-long period from mid-September to mid-October.
The total number of days above freezing during the growing season has ranged from as little as 111 days to as many as 155 days – a difference of more than one month.
The last day of March proved to be the warmest day in Greater Moncton since 03 November when the thermometer hit 17.1 C.
The daytime high reached a balmy 16.8 C and the New Brunswick hot spot was 19 C in Sussex which brought residents outdoors to walk, run, hike and play.
The maximum was actually close to the record for the date which was 17.5 C from 2006.
But a passing cold front will drop the temperature considerably overnight as rain changes to snow and Monday’s high struggles to reach slightly above freezing.
A warm air mass has surged into Western Canada this week bringing record temperatures to the region and also to the North.
Many communities from Yukon to Nunavut were well above freezing and into the double digits breaking March records.

A low pressure system from Quebec moved across New Brunswick Friday and into Saturday bringing a mixed bag of precipitation.
Snow began in Greater Moncton by late afternoon which later changed to ice pellets and then freezing rain followed by rain as the temperature climbed above freezing.
After 9 cm snow, 2.5 hours freezing rain and about 7 mm rain, some of the snow melted but by early evening, the thermometer dropped below freezing again which led to ice.
While this may be the last major weather event of 2018, Environment Canada is forecasting another system bringing snow or rain for New Year’s Day.
