Monday, June 9: first summer heat settles over British Columbia
The first heat wave of the season has arrived in southwestern British Columbia, bringing a significant rise in temperatures across Metro Vancouver. A ridge of high pressure dominated the weekend, pushing the atmosphere toward more stable conditions, with clear skies and temperatures nearing heat warning thresholds.
According to Environment Canada meteorologist Gary Dickinson, the special weather statement issued over the weekend aims to prepare residents for this first hot spell, at a time when people are likely not yet acclimatized.
Hot start to the week
Until the evening of Monday, June 9, highs are expected to reach 22°C (72°F) near the water and 28°C (82°F) further inland. Overnight lows will dip to around 13°C (55°F), keeping the nights mild and warm.
Tuesday: slight relief, but warmth lingers
The ridge will begin to weaken on Tuesday, allowing ocean air to move into the region. This will bring modest relief, with highs again around 22°C (72°F) on the coast and 26°C (79°F) inland. Still, the warm air mass will remain present through the evening.
Wednesday to Friday: gradual cooling, no rain
As the winds shift from east to west, cooler Pacific air will filter into the region. However, no rain or storm activity is expected. Daytime highs will range between 19°C and 21°C (66–70°F), with slightly warmer temperatures inland. Overnight lows are forecast around 10–11°C (50–52°F).
Dry and sunny work week ahead
Dickinson notes that no significant weather systems are on the horizon, which means a dry, mostly sunny week is in store. The weakening ridge will continue to shape the forecast, delivering calm weather but persistent warmth.
