RELATED: Why extreme heat is one of the world’s deadliest weather disasters
Humidex values will also climb through this week with increased atmospheric moisture, making conditions feel like the mid- to possibly even upper-30s. Humidity makes it harder for our sweat to evaporate, making the muggy heat more impactful on our bodies.
We’ll see the warmth attempt to nudge east into Ontario, where temperatures will likely rise into the 20s for a few days. However, the cool and unsettled trough over the Atlantic provinces may result in periods with warmer temperatures across northern portions of Ontario and Quebec than in southern parts of the provinces.
Above-seasonal temperatures are common beneath strong ridges of high pressure, and we’re set to see readings soar across the eastern Prairies during the latter half of this week.
Hot weather and humidity safety tips
-
Drink plenty of water. Avoid caffeine and alcohol, which can be dehydrating.
-
Avoid direct sunlight, especially during peak hours and when the UV rating is high.
-
Wear lightweight, loose-fitting clothing.
-
Use air conditioning when possible. If you do not have access to air conditioning, consider visiting a cooling centre, a shopping centre, or a public library.
-
Check on elderly relatives and other vulnerable neighbours.
Sweat cools us off by wicking heat away from our skin as it evaporates. Humidity prevents our sweat from evaporating efficiently—the trapped heat causing our body temperature to rise. This can lead to heat-related illnesses such as heat exhaustion and heat stroke.
Humidity also prevents nighttime lows from cooling off as much as normal, providing little to no relief from extreme daytime temperatures.
Day after day of high heat and humidity take a toll on those living without air conditioning, folks who have chronic illnesses, and the elderly.
