A heat warning has been in place since the start of the weekend in much of New Brunswick, Nova Scotia (except for Cape Breton) and Prince Edward Island.

In Greater Moncton, the temperature climbed to 30 C on Saturday and 29 C today but the forecast calls for 30 C on Monday and 31 C for Tuesday and Wednesday.

Overnight lows are not expected to drop that much either hovering around 18 to 19 C.

While humidity has been relatively low this weekend at around 50 percent or less, Environment Canada says the warm air mass will become more humid this week.

The only relief will be along the Fundy coast where temperatures will stay in the low 20s.

New all-time record highs across Europe

The second summer heat wave gripping Europe peaked on Thursday with new all-time record highs set in several countries.

Paris climbed to a stifling 42.6 C breaking the French capital’s previous record high of 40.4 C from July 1947.

The temperature climbed above 40 C in the Netherlands at Gilzen-Rijen for the first time ever when it reached 40.7 C and Lingen, Germany set a new country record of 42.6 C.

Records were also set in Belgium (41.8 C) and Luxembourg (40.8 C).

The UK Met Office is verifying whether a high of 38.7 C at Cambridge is the warmest temperature ever for the United Kingdom.

Historic heat in Western Europe

The jet stream has carried hot air from northern Africa across western Europe which is shattering all-time record highs in numerous countries.

The second extreme heat wave this summer has set new maximums in Belgium at 38.9 C, the Netherlands at 39.2 C and Germany at 40.5 C.

Bordeaux, France reached 41.2 C on Tuesday which was its highest temperature ever.

Thanks to the urban heat island effect, major cities are more prone to hot weather than rural areas and don’t cool down that much overnight.

On Thursday, the UK Met Office believes Britain could smash its current historic high of 38.5 C recorded in Faversham in August 2003.

Hottest weather yet?

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.

Brief heat wave ends

In less than two hours, the temperature in Greater Moncton dropped from 31.1°C to 24.0°C late this afternoon – a difference of seven degrees.

A cold front moved through New Brunswick with thunderstorms marking an abrupt end to the summer’s first brief heat wave.

Environment Canada even issued a tornado warning for the Grand Lake area after a possible twister developed south of Boiestown.

The warning was lifted after 30 minutes and no damage or injuries were reported.

Record highs have been broken in a number of communities across the Maritimes.

Friday, 05 July:

  • Kouchibouguac NP, new record 31.1°C, old record 33.9°C from 1939
  • Grand Manan, new record 31.7°C, old record 30.0°C from 1999
  • Halifax Stanfield Airport, 32.7°C, old record 31.4°C from 2013

Greater Moncton was within a hair of breaking a record Saturday and Sunday it was the warmest on that date since 2013.

  • 05 July, high 34.0°C, record 34.2°C from 2018
  • 06 July, high 31.4°C, record 35.0°C from 1911

Baked Alaska!

Hot weather is rare for Anchorage which has reached an all-time high of 32°C (90°F) but in Alaska’s interior, heat is not unknown.

Fairbanks has previously topped out at 37°C (99°F) and the all-time Alaska state high was 38°C (100°F) in Fort Yukon from 1915.

Meteorologists say a strong high pressure system has been sitting stationary over the state creating the heat wave.

Smoke from wildfires has drifted into many communities creating air quality problems.

Neighbouring Yukon has also been affected by smoke with Whitehorse and Dawson City recording above normal temperatures in the high 20’s since late June.

Europe sizzles in heatwave

Europe heatwave

A rare June heatwave has blasted Europe with record breaking warm temperatures in numerous countries.

France recorded its highest temperature ever on Friday near the southern city of Montpellier at 45.9°C.

The hottest day of the year in the United Kingdom was Saturday when London Heathrow reached 34°C.

Meteorologists say hot air from the Sahara Desert is responsible for the extreme heat which has claimed several lives, shut down schools and led to water restrictions.

Germany, Poland and the Czech Republic have all recorded their highest June temperatures ever.

August 2018 – Heat continues!

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.

Calgary sets new heat record

Calgary hit an all-time record high on Friday when the thermometer climbed to 36.5°C which eclipsed the previous record of 36.1°C set 85 years ago.

Environment Canada had issued heat warnings for more than 100 regions in Alberta, British Columbia, Saskatchewan and Manitoba.

Besides the heat, smoke from forest fires have caused poor air quality throughout Western Canada.

A cold front lowered temperatures in Alberta to near seasonal values for the weekend but the heat lingered in the eastern Prairies.
