For Immediate Release
Friday, June 20, 2025 | 12:00 p.m. | Windsor-Essex County
Based on information from Environment and Climate Change Canada, Dr. Mehdi Aloosh, Windsor-Essex County Health Unit's Medical Officer of Health, has issued an Extended Heat Warning from Saturday, June 21 until Wednesday, June 25 for Windsor and Essex County.
An extended heat warning is issued when three or more consecutive days are forecasted to have a daytime high temperature greater than or equal to 31°C and a nighttime temperature greater than or equal to 21°C, or a humidex greater than 42°C.
Everyone is at risk from heat, especially older adults, infants and young children, people who work or exercise in the heat, and those with certain medical conditions. Warning signs of heat-related illness include dizziness, headache, nausea or vomiting, weakness, and confusion. If you experience any of these symptoms, seek immediate medical attention. Check on friends, family, and neighbors frequently during heat events, and even after the weather cools off, as they may still feel the effects of the heat.
Heat-related illnesses are preventable! You can prevent a heat illness by following these tips to stay cool:
- Monitor local weather forecasts and warnings regularly
- Drink plenty of water, even if you don’t feel thirsty
- Wear a wide-brimmed hat and lightweight, loose-fitting clothing
- Take a cool bath or shower
- Limit outdoor activities to the coolest part of the day
- Do not leave children, adults, or pets in parked cars
- Arrange regular visits for family members, neighbors, or friends during very hot days in case they need assistance
- If you have an air conditioner, make sure it works properly before the hot weather starts. Otherwise, find an air-conditioned spot close by, where you can cool off for a few hours during very hot days (e.g., local pool, library, recreational center, mall).
- Learn about ways to keep your home cool during the summer (e.g., keep window shades or drapes drawn and blinds closed on the sunny side of your home)
