The next heat wave across Eastern Canada could be the warmest period yet this summer with daytime highs in the low 30’s C and humidex values near 40.

Southern Ontario and Southern Quebec have been blanketed with heat warnings from Environment Canada with hot, humid days and warm nights expected this weekend.

Temperatures in the Maritimes for Saturday and Sunday could reach 30 C but a cold front will bring cooler and drier air by Monday.

A mini heat wave already brought highs of 29 C and 30 C earlier this week in Greater Moncton.

Here comes the heat!

After a cool and wet start to summer, a blast of heat is heading to the Maritime Provinces over the next few days.

Environment Canada has issued heat warnings for most of New Brunswick – excluding the Fundy coast – and western Nova Scotia while other areas under a special weather statement.

A warm, humid air mass is moving into the region today raising daytime temperatures to 30°C or more.

Humidex values near 40 are expected and overnight lows may not fall below 18°C providing little relief from the heat.

Near normal values will return late Saturday as a cold front arrives.

Heat warnings are also in place for parts of Ontario and Quebec where it climbed into the low 30s yesterday.

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.

May 2019 – Miserable!

Irishtown Nature Park, Moncton, 20 May 2019 (Dearing)

May 2019 proved to be the coldest May since 1974 in the Maritimes with temperatures about two or three degrees below normal.

The month started out with some warmth in Greater Moncton but it turned colder near the middle with snow recorded as late as the 21st before a slight recovery at the end.

Overnight lows were cold with six nights either at or below freezing and most minimums were in the low single digits.

Cold, damp and cloudy weather stunted growth and forced farmers to delay planting because fields were saturated.

Only three days reached or exceeded 20°C and the thermometer came nowhere near 30°C at any time of the month.

Frost advisory!

Desmoiselles Beach, Hopewell Rocks, 12 May 2019 (Dearing)

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.

Finally above freezing!

For the first time in 12 days, the daytime high in Greater Moncton finally climbed above freezing with a balmy high of 1°C today!

The normal maximum for early March in Southeast New Brunswick is 2°C with a minimum of -8°C.

The last third of winter has been especially cold with overnights consistently below -10°C and even as low as -20.1°C early Friday.

However, there is some good news – Environment Canada is forecasting that the next five out of six days will have highs above freezing.

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.

A hot July also translated into a hot August in what has to be one of the warmest summers in Southeast New Brunswick since 1940.

In Greater Moncton, the thermometer climbed to 30°C or higher on 6 days during August and never dropped below 18°C during 9 overnights.

Fans, air conditioners and other cooling units sold out at stores across the region and many weren’t able to reorder more.

Although it seemed rather dry, rainfall was actually slightly above average thanks to a single rain event which delivered nearly 60 mm which is 60 percent of the monthly total.

Summer heat sizzles Europe

A warm air mass from north Africa has caused temperatures to skyrocket into the 40s C throughout the Iberian Peninsula challenging all-time heat records in Europe.

Lisbon, Portugal set a new maximum for 04 August at 44°C and even overnight lows are barely falling below 30°C.

Hundreds of firefighters are battling wildfires in the Algarve region and in neighbouring Spain.

The water in some rivers has become so overheated that fish are dying on a mass scale.

Forecasters say the heat is moving east and will affect France and Germany over the next few days.

The hottest temperature ever recorded in Europe is 48°C (118.4°F) set in Athens, Greece in July 1977.
