Environment Canada issues heat advisory for southern Vancouver Island

Environment Canada has issued a special weather statement for Greater Victoria, the Malahat, and other parts of southern Vancouver Island, warning of an early season heat event expected to begin Saturday and persist into early next week.

According to the advisory, a ridge of high pressure is bringing above-seasonal temperatures to the south coast.

Daytime highs are expected to range from the high 20s to low 30s, while overnight lows will remain in the low to mid-teens.

The advisory notes that heat events early in the season can carry heightened risk, as many residents may not yet be acclimatized to warmer temperatures.

“Fans alone cannot effectively lower core body temperature, especially for older adults,” Environment Canada stated in its release. “If you or someone you care for is experiencing symptoms of heat illness, find a cooler space.”

Symptoms of heat-related illness include heavy sweating, rash, cramps, dizziness, fainting, and the worsening of pre-existing health conditions.

Officials recommend residents block direct sunlight by closing curtains or blinds, and use fans to circulate cooler air from outside rather than relying on them as a primary cooling method.

In addition to the general warning, drivers are being cautioned that weather in mountainous areas like the Malahat Highway between Goldstream and Mill Bay can shift rapidly, potentially creating hazardous road conditions.

Ahead of the peak heat, the Victoria area will see a gradual warming trend beginning Thursday:

• Thursday, June 5 – High of 22°C, low of 11°C
• Friday – High of 22°C, low of 11°C
• Saturday – High of 24°C, low of 12°C
• Sunday – High of 26°C, low of 13°C
• Monday – High of 26°C, low of 13°C

No precipitation is forecasted, and skies are expected to remain sunny throughout the stretch.

As temperatures rise, residents are encouraged to check in on vulnerable individuals, stay hydrated, and avoid strenuous outdoor activities during the hottest parts of the day.
