A heat warning has been issued for Prince Edward Island, with temperatures from Sunday through Wednesday forecast to reach 31 C but feel as high as 39.

“A very warm and humid air mass will settle over the region for the next couple of days. Little relief is expected at night with elevated overnight temperatures,” Environment Canada said on its weather alerts site as the warning was posted.

“Current guidance indicates conditions will begin moderating after Wednesday,” the agency said. 

The heat warning was posted at 3:50 p.m. AT on Saturday, a day after Old Home Week events began in Charlottetown and at a time when free entry to the P.E.I. National Park has popular North Shore beach parking lots filled to capacity most sunny days. 

Hot, dry weather continues in P.E.I. amid burning restrictions

The hot, dry summer is making it tough on Island farmers and landscapers. Some municipalities have also issued fire bans and are asking residents to try to use less water. CBC’s Laura Meader reports.

Park officials have more to worry about than full parking lots, though. 

“Due to extremely dry conditions and until further notice, by order of the superintendent, no fires will be permitted in Prince Edward Island National Park,” Parks Canada said in a news release late Saturday afternoon.

“We thank visitors for their co-operation with this measure, aimed to reduce the extreme risk of forest fires. Conditions will be monitored on a daily basis and restrictions will be adjusted accordingly.”

Environment Canada said parts of coastal Prince Edward Island will feel a bit cooler as inland areas swelter.  

“Extreme heat can affect everyone’s health,” the agency warned. “Determine if you or others around you are at greater risk of heat illness. Check on older adults, those living alone and other at-risk people in-person or on the phone multiple times a day.”

Signs of heat exhaustion can include headaches, nausea, dizziness, thirst, dark urine and intense fatigue.
