October 2019 – Gradual easing into fall

Centennial Park, Moncton, 14 Oct 2019 (Dearing)

Daytime highs were consistently in the mid-teens in Southeast New Brunswick during October which usually sees a sharp drop in temperature as the month progresses.

The average temperature was 0.7°C above normal in Greater Moncton with two days failing to reach 10°C and the warmest maximum on the last day, 19.3°C.

Six days had lows below freezing with some light frost but there was no hard freeze allowing vegetation to flourish.

The precipitation total mostly came from five rainfall events with not a single snowflake recorded.

Fall foliage peaked prior to Thanksgiving weekend and several strong wind events left few leaves on trees by Halloween night.

Scattered frost!

It was a cold morning in the Maritimes and frost advisories were posted for all three provinces.

Scattered frost was recorded in many areas including Greater Moncton where the thermometer fell to -0.4°C at the airport which is close to the 2008 record low of -1.2°C.

However, a minimum of -4.4°C was set in the area in 1945.

This was a light frost and much earlier than the average date of 04 October.

The Year Without Spring

It snowed overnight in Southeast New Brunswick.

About 0.6 cm of wet snow was recorded at the Greater Moncton Airport and even higher accumulations around the region.

In recent history, I can’t recall a snowfall this late in the month of May.

With meteorological summer arriving in 10 days and astronomical summer in barely a month, I’ve concluded that 2019 is the “Year Without Spring”.

The cold, damp weather has impacted farmers who are at least two weeks behind in planting crops due to saturated fields.

Sidewalk patios are eerily empty and winter parkas are still being worn by many.

A frost advisory has been posted for tonight and another one will likely be posted in two days as temperatures drop to near freezing again overnight.

Will the weather improve anytime soon?

A high of 20°C is forecast for Saturday but keep in mind we often hit 30°C before the beginning of June.

Frost advisory!

The Victoria Day long weekend marks the unofficial start of the summer season in Canada when opening up the cottage or camping are on the agenda.

However, many residents are still wearing heavy, winter jackets and gloves as daytime highs struggle to reach 10°C in Southeast New Brunswick.

The normal maximum in Greater Moncton is about 18°C but the long range forecast shows it won’t be that warm for another six days!

Environment Canada has issued a frost advisory for all of New Brunswick and most of mainland Nova Scotia as the overnight low drops to near freezing.

On the upside, the advisory means the growing season is now officially underway but on the downside, it’s not warm enough to plant anything.

Frost free season approaches

May is here which means it won’t be long before Jack Frost visits Atlantic Canada for the last time this spring.

Mid to late May is typically when the last frost arrives in Greater Moncton, early in the month for Halifax and late April for Yarmouth.

Early to mid June dates are normal for most of Newfoundland and Labrador.

Last year in New Brunswick and Nova Scotia, frost appeared as late as early June which proved disastrous for grape, blueberry and strawberry farmers.

Risk of frostbite

A good old fashioned January cold snap continues in New Brunswick with well below normal temperatures since last weekend.

Wind chill values have dropped to -30 giving the risk of frostbite on exposed skin.

After a frosty -21.4°C in Greater Moncton earlier this week, forecasters say a further tumble to -23°C is likely before a potent winter storm arrives on Sunday.

Environment Canada is tracking a system moving across the U.S. which is expected to bring at least 30 cm of snow, 50 mm of rain, a period of freezing rain and strong winds to the Maritimes.

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.

September 2018 – Warm and wet

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.

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.

A chilly start!

It may have been the warmest summer in the Maritimes in almost a century but some parts of the region woke up to below freezing temperatures and frost this morning!

That means some areas had a growing season which barely lasted 100 days since the last spring frost for many was 04 June.

Greater Moncton was definitely chilly with an early morning low of 3.0°C which was close to the record low of 1.1°C from 1956.

Here are some of the nippy overnight lows:

  • Edmundston, NB  -2.0°C
  • Woodstock, NB  -0.8°C
  • Red Pines, NB  -0.7°C
  • Fredericton, NB  0.1°C
  • Upper Stewiacke, NS  -0.4°C
  • Maple Plains, PEI  1.4°C
