Environment Canada is forecasting a stretch of hot, sunny weather for Port Alberni starting Wednesday, August 5, 2026, with temperatures reaching 32 C and a humidex making it feel more like 34. The UV index will hit 8, which is considered very high, so anyone heading outside is urged to take extra care in the sun.
The heat is expected to stick around through the end of the week, though temperatures will slowly ease. Thursday will see a high of 31 C with a humidex of 33, Friday should reach 30 C, and Saturday will cool off to about 26 C. Overnight lows will sit between 12 C and 13 C.
There are no heat warnings in effect right now, but the province’s Heat Alert and Response System has three colour-coded levels if conditions get worse: yellow for unusually high temperatures over a couple of days, orange for very high heat lasting three or more days, and red for dangerous, prolonged heat like the 2021 Heat Dome. That event pushed Port Alberni to an all-time record of 42.7 C and led to 619 heat-related deaths across B.C.
Health officials remind everyone that even without a warning, high heat can be risky, especially for older adults, people with chronic health conditions, pregnant people, and young children. Signs of heat stroke include confusion, fainting, nausea, rapid breathing, and a body temperature above 39 C. If you see these symptoms, call 9-1-1 right away.
With the UV index at very high levels, unprotected skin can burn quickly. Try to stay out of direct sun between 11 a.m. and 3 p.m., wear UV-blocking sunglasses, stick to the shade, and reapply sunscreen every two hours or after swimming or heavy sweating.
Anyone without air conditioning can find relief by visiting public places like libraries or community centres, taking cool showers, and drinking plenty of water. Checking in on neighbours who may be more vulnerable is also a good idea during hot spells like this.
