Coolest day since May

Irishtown Nature Park, 05 October 2019 (Dearing)

Chilly temperatures across the Maritimes on Friday made it feel more like early November than early October.

In Greater Moncton, the daytime high for 04 October was only 8.2 C which means it was the coolest day since 22 May when the maximum was only 8.6 C.

Halifax, Charlottetown, Saint John and Fredericton also had highs below 10 C.

The normal high for the first week of October in Southeast New Brunswick is 15 C with an overnight low of 4 C.

June 2019 – Mild and wet

The average monthly temperature for June in Greater Moncton was at least close to normal compared to a damp, cold May.

While daytime highs climbed to 20°C or higher on 20 days, significant heat was scarce and the thermometer didn’t even get close to 30°C.

Rainfall was heavier than normal – a measurable amount was recorded on 21 days – following a trend which began in early spring.

About three-quarters of the precipitation fell during the last ten days of the month.

Chilly nights!

Last Zero
The last couple of nights have been chilly across New Brunswick with overnight lows in the low single digits.

While Greater Moncton fell to 5.5°C which was a few degrees away from the record, the same minimum in Bouctouche was cold enough to set a new low.

Edmundston dipped to a nippy 1.1°C which tied its record as did Grand Manan when it dropped to 3.8°C.

Over the last six years in Greater Moncton, the chart above shows temperatures have not fallen to the freezing point or lower after early June.

When will it reach 30°C?

First 30
It’s been a cold spring in Greater Moncton and the thermometer didn’t reach 20°C until 25 May – so when will it hit 30°C?

According to Environment Canada, the average date since 2013 has ranged from mid-May to late June but mainly late May.

While June has been warmer to date in Southeast New Brunswick, the long range forecast is calling for cooler conditions.

Will we have to wait until July this year?

April 2019 – Wet and chilly

Spring can be the most disappointing season of the year in New Brunswick and April 2019 was no exception with cloudy, cool and often wet conditions.

Surprisingly, Greater Moncton was close to normal in temperature but double the average amount of rain fell along with slightly more snow than usual.

Melting snow and heavy precipitation led to more disastrous flooding along the St. John River – almost as bad as last year’s historic water levels.

Only one day was fully below freezing and while nights weren’t that cold, daytime highs often struggled to reach the double digits.

Autumn 2018 in review

Autumn2018
Meteorological autumn spanning the months of September, October and November proved to be cooler and much wetter than normal in Greater Moncton.

While September felt more summer-like, it turned decidedly colder by mid-October and a big drop by mid-November with a low within two degrees of a 30-year record.

Precipitation was heavy with more than 100 mm of rain falling above normal and snow first appeared in late October and again in heavy amounts by late November.

October 2018 – Cool and wet

October 2018 proved to be very different from October 2017 in Southeast New Brunswick.

While it was warm and dry last year in Greater Moncton (the second warmest October since 1881), it was the opposite this year – cool and wet.

Temperatures were below normal with only one day reaching 20°C and a hard frost arrived by mid-month.

Only seven days were dry with three major rainfall events and snow fell on three days – briefly settling on the ground twice.

Warm, summer weather picked up in September where it left off in August in Southeast New Brunswick.

But the passage of a cold front marked a drastic temperature drop on the 18th and suddenly it felt like fall in Greater Moncton.

The thermometer continued to plunge and sank to -1.9°C on the 25th with light, scattered frost although most vegetation was spared severe damage.

Precipitation was actually above normal although heavy amounts fell in a handful of rainfalls.

AVERAGE 14.4°C (about 0.8 degrees ABOVE normal)

Frost forms under harvest moon

A clear night under a brilliant harvest moon lowered the temperature to -1.9°C in Greater Moncton this morning with some scattered frost.

Most sensitive vegetation survived as the thermometer fell below zero for less than six hours.

Many weather stations across New Brunswick had readings near or a few degrees below freezing.

On average, the first fall frost date in Moncton is 02 October with an growing season of 131 days.

However, a record breaking low of -3.2°C on 04 June brought a late frost (about two weeks later than usual) which proved devastating for farmers and gardeners.

So despite enjoying a long and warm summer, the frost-free season lasted 112 days which is about 19 days shorter than usual.
