The first heat wave of the summer that is blanketing Sarnia-Lambton is record setting according to Environment Canada.
The temperature climbed to 34.5 C on Sunday, June 22, surpassing the previous record of 33.9 C set in 1988.
The record for June 23 is 32.9 C, set in 1983.
With a forecasted high of 36 C, Environment Canada Warning Preparedness Meteorologist Steven Flisfeder said we'll likely set a new record again on Monday.
Flisfeder said the early summer heat wave is thanks to a hot and humid airmass coming from the southern U.S.
"In addition, we have a fairly stagnant high pressure system over the area that's kind of blocking any new systems from coming in to sweep out those conditions," said Flisfeder.
He said there is relief on the way as the high pressure system starts to weaken.
"Tuesday will be ever so slightly less warm with temperatures around 32 C," said Flisfeder. "But, you'll also have a chance of showers and the risk of thunderstorms so you could get some relief just because of that precipitation. Overnight Tuesday, you'll have temperatures finally dropping below that 20 degree mark so that should break this heat event for the Sarnia-Lambton area."
We're being reminded to drink plenty of water and seek cool places such as tree-shaded areas, swimming pools, or air-conditioned buildings.
Lambton Public Health said in high temperatures and humidity, your body may not be able to cool properly which can lead to heat exhaustion or even heat stroke.
Outdoor workers should take regularly scheduled breaks in a cool place, and people or pets should never be left inside a parked vehicle.
Environment Canada said on average we'll see above seasonal temperatures this summer, which officially started last Friday night.
