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.
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?
Today marks the beginning of the 2019 hurricane season which will run until the end of November.
For a record fifth consecutive year, storm activity began before the 01 June official start date when Subtropical Storm Andrea formed on 20 May.
The U.S. National Oceanic and Atmospheric Administration (NOAA) is forecasting a near normal season with 9–15 named systems, 4–8 hurricanes, and 2–4 major hurricanes.
The Canadian Hurricane Centre begins issuing statements when a storm is within three days of entering a response zone covering Eastern Canada and adjacent waters.
After a cold and wet spring in New Brunswick, what will summer be like?
The Weather Network has unveiled its summer 2019 forecast and if you were hoping for warmer temperatures, it appears you may have to wait a little longer.
TWN suggests the season will be changeable and humid with cool weather in June but warmer than normal temperatures arriving in July stretching into August.
Extended periods of dry weather could lead to short term drought in parts of the Maritimes but overall precipitation will likely be near normal.
What about the spring 2019 forecast from The Weather Network?
TWN noted a cold wave in early March would be followed by a warmer pattern later in the month with more consistent spring-like weather by early April.
Both temperatures and precipitation were expected to be near normal.
So was the seasonal forecast accurate?
While early March was cold in Greater Moncton with a bitter low of -20.1 C, a warmer pattern never really developed except for a brief shot of warmth at month end.
April had some warmth in the middle but that fizzled near the end and while May started off strong, a cold pattern held steady for the second half of the month.
Precipitation was below seasonal in March, well above average in April and slightly above normal for May.
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.
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.

The same storm system which brought severe weather to Ontario and Quebec – including tornadoes – crossed through New Brunswick overnight.
Strong low pressure caused gusty winds up to 72 km/h at the Greater Moncton International Airport which turned out to be the windiest day since 02 June.
A wind gust of 85 km/h was reported in Charlo.
NB Power said almost 10,000 customers lost power at the peak of the storm thanks to trees and branches falling on utility lines.
Incidentally, fall officially arrives later tonight with the autumnal equinox at 10:54 pm ADT.
