Hamilton and nearby regions face a prolonged heat warning with humidex values up to 40. Relief expected by Thursday, says Environment Canada.
Region Gripped by Prolonged Heatwave
A severe heat warning remains in effect for Hamilton, Niagara, Brant, and surrounding areas as sweltering temperatures and high humidity persist throughout the week. Environment Canada has forecast daytime highs between 29°C and 32°C, with humidex values soaring between 35 and 40, marking one of the most intense heat stretches this summer.
Public Health Alert Issued
The warning, updated by Environment Canada on Sunday, emphasizes the serious health risks posed by the prolonged heat. The agency advises residents to take precautions, particularly for vulnerable populations such as seniors, young children, and individuals with pre-existing health conditions. Symptoms of heat exhaustion—including headache, dizziness, nausea, and fatigue—should be treated immediately with rest and hydration.
Conditions Expected to Ease by Thursday
While a temporary dip in humidity may offer brief relief on Monday, Environment Canada warns that muggier conditions are likely to return Tuesday. A more significant shift in the weather pattern is expected late in the week, potentially ending the heatwave by Thursday night.
Hamilton Responds with Cooling Resources
In response to the alert, the City of Hamilton has extended its heat warning measures, activating a network of “cool places” in partnership with local community agencies. Locations are marked with “Cool Down Here” signs, offering residents refuge from the oppressive heat. Additionally, all regularly scheduled open swims at city pools—both indoor and outdoor—are now free of charge for the duration of the heat event.
Safety Tips to Beat the Heat
To mitigate the impact of extreme heat, the City of Hamilton advises residents to:
- Stay hydrated with water; avoid alcohol and caffeine.
- Seek air-conditioned environments or visit city-designated cool places.
- Dress in lightweight, light-coloured clothing and use sun protection.
- Reduce physical activity during peak heat hours.
- Take cool baths or showers and keep indoor spaces shaded.
- Never leave children or pets unattended in vehicles.
Landlords are also urged to ensure tenants have access to adequately cooled living spaces, especially during peak daytime hours.
Community Urged to Check on At-Risk Individuals
With heat-related illnesses posing serious risks, officials stress the importance of checking in—by phone or in person—on those who live alone or may be especially susceptible. Environment Canada reminds all residents that taking early action is critical to preventing emergencies.
