Winnipeg is heading into a prolonged stretch of hot and humid weather, with temperatures climbing into the low-to-mid 30s and humidex values expected to approach 45°C in some areas. Environment Canada says the heat is expected to begin Friday and continue well into next week, creating potentially dangerous conditions for anyone spending time outdoors.
Whether you’re working outside, attending summer events, or simply trying to stay comfortable at home, here’s what you need to know to stay safe during Winnipeg’s latest heat wave.
Why This Heat Wave Is Different
Unlike a typical hot summer day, this event is expected to last for several days with little overnight relief. When temperatures remain high overnight, your body has less time to recover from the daytime heat, increasing the risk of heat-related illnesses.
High humidity will also make it feel much hotter than the actual air temperature, making outdoor activities more strenuous.
Stay Hydrated
One of the most important things you can do is drink plenty of water throughout the day.
- Drink water regularly, even if you don’t feel thirsty.
- Carry a reusable water bottle when you’re out.
- Avoid excessive alcohol and caffeinated drinks, which can contribute to dehydration.
Limit Time Outdoors
If possible, schedule outdoor activities during the early morning or later in the evening when temperatures are lower.
If you must be outside:
- Take frequent breaks in the shade or indoors.
- Wear lightweight, loose-fitting, light-coloured clothing.
- Wear a wide-brimmed hat and sunglasses.
- Apply sunscreen regularly.
Keep Your Home Cool
If you don’t have air conditioning, there are still ways to reduce indoor temperatures.
- Close blinds and curtains during the hottest part of the day.
- Open windows overnight when temperatures drop.
- Use fans to circulate air, but remember that fans alone may not prevent heat-related illness during extreme temperatures.
- Spend time in air-conditioned public buildings such as shopping malls, libraries, or community centres if your home becomes too warm.
Know the Signs of Heat Illness
Heat-related illnesses can develop quickly.
Symptoms of heat exhaustion include:
- Heavy sweating
- Dizziness
- Weakness
- Headache
- Nausea
- Muscle cramps
Move to a cool place, loosen clothing, drink water, and cool your body with wet towels or a cool shower.
Heat stroke is a medical emergency.
Call 911 immediately if someone experiences:
- Confusion
- Loss of consciousness
- Very high body temperature
- Hot, red skin
- Seizures
While waiting for emergency responders, move the person to a cooler location and begin cooling them with cold water or ice packs if available.
Check on Family, Friends and Neighbours
Older adults, infants, young children, people with chronic medical conditions, pregnant individuals, and those who work outdoors are at greater risk during periods of extreme heat.
Take a few minutes each day to check on loved ones, neighbours, or anyone who may need assistance staying cool.
Don’t Forget Your Pets
Pets are also vulnerable to heat.
- Ensure they always have fresh water.
- Provide plenty of shade.
- Avoid walking dogs on hot pavement during the afternoon.
- Never leave pets in parked vehicles, even for a few minutes.
Never Leave Anyone in a Parked Vehicle
The temperature inside a vehicle can rise dangerously within minutes, even if the windows are cracked open.
Never leave children, older adults, or pets unattended in a parked vehicle.
Stay Informed
Weather conditions and heat warnings can change quickly. Monitor local forecasts throughout the week and follow any advice issued by Environment Canada or the City of Winnipeg. Officials are encouraging residents to take precautions as southern Manitoba experiences several days of intense heat and humidity.
As Winnipeg experiences one of the hottest stretches of the summer so far, taking a few simple precautions can go a long way in preventing heat-related illness. Stay hydrated, avoid strenuous activity during the hottest part of the day, look out for vulnerable family members and neighbours, and remember that no errand or outdoor activity is worth risking your health in extreme heat.
