July 2017 – Warm and dry

Upper Salmon River, Alma, NB, 30 July 2017 (Dearing)


As the month of July progressed in Southeast New Brunswick, lawns turned brown and forests became extremely dry as temperatures soared with little rain fell. 

Greater Moncton only received one-third of its normal monthly rainfall and 15 days had no precipitation at all. 

The heat was steady throughout July with 20 days reaching 25 C or higher and four days climbing to 30 C or more. 

A brief cool down near month end lowered daytime highs to the low 20s C and brought a chilly overnight low of 6.9 C.

Thunderstorm activity was common throughout Southeast New Brunswick in June and all but ten days had at least a trace of rainfall.

But precipitation amounts were generally light in Greater Moncton except for two major rain events – 36.6 mm fell on 09 June along with a peak wind gust of 102 km/h and 21.2 mm fell on 24 June.

Temperatures were cool during the first week of the month with an overnight low dropping to the freezing point although frost was generally avoided thanks to cloudy skies.

Summer-like conditions arrived by mid-month and many daytime highs climbed well into the 20’s C and reached 30 C or higher three times.

May in Southeast New Brunswick certainly lived up to its unpredictable nature as a transitional month between winter and summer.

Overall temperatures were above normal in Greater Moncton but oddly enough some of the coolest days were in the last third of the month.

Many days were cloudy and rainfall was heavy with only seven days without at least a trace of precipitation.

By the final week, trees were in full leaf or blossom and perennials were in full bloom.

April 2017 – Spring sputters

Spring seldom arrives on time in New Brunswick and this year is no exception even though April was actually warmer than normal in Greater Moncton.

The month can be broken into four segments – cold in the beginning, then warm, turning cold again and finally warm again near the end.

A consistent snow cover began on 27 November and disappeared briefly in late January before finally melting for the season by 10 April.

Precipitation overall was below average with much less snow than normal.

March 2017 – Cold and snowy

Winter just wouldn’t let go of its grip on Southeast New Brunswick during March. 

Overnight lows were extremely cold especially during the first half of the month. 

Daytime highs were often very chilly and barely climbed above freezing even during the last week. 

Oddly enough, the maximum temperature in February was actually warmer than all of March. 

Precipitation was below normal overall but snow did fall on 22 of 31 days.

Three major winter storms including a blizzard were part of a very active weather pattern in Greater Moncton during February.

While snowfall was below normal in January, it made up for it in February with more than double the average amount recorded.

Temperatures were above normal but oddly enough it was still warmer in January which is typically the coldest month.

The final week felt like spring with mild temperatures climbing above 10 C which was enough to melt most of the snow which had fallen during the previous three weeks.

The defining weather event of January 2017 in New Brunswick was the devastating ice storm which brought down power lines and poles leaving more than 133,000 electricity customers in the dark for days.

Freezing rain and ice pellets began falling in Greater Moncton and Southeast New Brunswick on 25 January and the storm eventually moved northeast to Miramichi and the Acadian Peninsula.

Emergency shelters were set up in churches and community centres and the military was called in to help after some households were still without power a week later.

While overnight lows became frigid during the early and middle parts of the month, daytime highs were generally much milder than usual.

December 2016 -Weather rollercoaster

So many ups and downs occurred during December in Southeast New Brunswick, one might say we were riding a weather rollercoaster.

Early on 17 December in Greater Moncton, the thermometer fell to a monthly (and almost record) low of -22.1 C which then rose to a monthly high of 10.6 C only 36 hours later before eventually dropping again to -18.6 by late on 19 December.

Although many nights were extremely cold (eight below -15 C), daytime highs were often slightly above or below freezing which overall led to a slightly below average monthly temperature.

Most snow fell during the first half of the month (three snowfalls were 12 cm or higher) and although rainfall was below normal, overall precipitation was about average.

The first two-thirds of November proved to be mostly mild and dry in Greater Moncton although small amounts of rain did fall on most days.

The last ten days of the month took a decidedly colder turn and while overnight lows weren’t very cold, daytime highs struggled in the low single digits.

A blast of winter came at the very end with 26 cm of heavy, wet snow which brought up precipitation amounts but the total was still almost 40 percent below normal.

October 2016 – Mild then cold

It’s not surprising the days gradually get cooler in October but it was a sudden change in Greater Moncton when temperatures went from mild to cold during the last week of the month.

A warm, humid daytime high of 20.5 C on 22 October will undoubtedly be the last time the thermometer climbs above 20 C in this calendar year.

Although a couple overnight lows fell below freezing early in the month, a hard frost was not reported until 27 October.

Almost 50 mm of rain fell on Thanksgiving weekend in Southeast New Brunswick – far less than other parts of the Maritimes such as Cape Breton Island with over 220 mm.
