Summer doesn't officially begin until Thursday evening, but the heat is being turned up in a big way over Prince Edward Island this week.

Hot and humid weather is expected to blanket the Island, with temperatures forecast to hit a maximum of 31 C Wednesday and 32 C the next day.

The humidex could make it feel as hot as 38 C by the time the summer solstice arrives at 5:50 p.m. AT on Thursday.

That prompted Environment Canada to issue a heat warning Tuesday afternoon for all three of P.E.I.'s counties for Wednesday and Thursday.

"Heat warnings are issued when very high temperature or humidity conditions are expected to pose an elevated risk of heat illnesses, such as heat stroke or heat exhaustion," the warning reads.

"Nighttime lows are forecast to remain fairly warm, limiting overnight cooling. Some relief may be found in communities located very close to the water."

P.E.I.'s Chief Public Health Office issued a news release Tuesday morning urging Islanders to protect themselves from heat-related illnesses such as heat exhaustion and heat stroke. Advice includes:

  • Stay hydrated: Drink plenty of water throughout the day, even if you do not feel thirsty. Avoid alcoholic and caffeinated beverages, which can lead to dehydration.
  • Wear appropriate clothing: Choose lightweight, loose-fitting and light-coloured clothing. Wear a wide-brimmed hat and sunglasses for added protection.
  • Use sunscreen: Apply a broad-spectrum sunscreen with an SPF of 30 or higher to all exposed skin. Reapply every two hours, or more often if swimming or sweating.
  • Food safety: Keep perishable foods refrigerated below 40°F to prevent bacterial growth. Avoid leaving food out for an extended period of time. Use insulated coolers with ice packs when transporting perishable groceries.
  • Check on vulnerable people: Ensure that young children, the elderly, those with chronic illnesses, people who work outside, people experiencing homelessness, and people taking specific medications are staying cool and hydrated. Never leave anyone, especially children and pets, in a parked car, even with the windows down.
