About CYHC Weather Station

Vancouver Harbour CWOS (CYHC) provides weather observations for the Vancouver waterfront area. Located at sea level in the heart of the city, this station captures the maritime-influenced conditions typical of coastal Vancouver.

The station's harbour location means temperatures are heavily moderated by the Pacific Ocean. Environment Canada maintains the observation network and provides official climate data.

Seasonal Trading Considerations

Winter (December - February): Mild and very wet with highs 5-8°C (41-46°F). Snow rare at sea level but common in nearby mountains.

Spring (March - May): Gradual warming and drying. Temperatures climb from 10°C to 18°C.

Summer (June - August): Warm and dry with highs 22-25°C (72-77°F). Very little rain. Occasional heat waves can bring 30°C+.

Autumn (September - November): Cooling with increasing rain. Pineapple Express storms begin.

Trading Tips for Vancouver

Pacific Ocean moderation keeps Vancouver temperatures remarkably stable - extreme heat and cold are both rare.

The Pineapple Express - warm, moist air from Hawaii - can bring unusual warmth in winter, sometimes pushing temperatures above 15°C.

Arctic outflows from the interior can briefly bring cold, dry conditions and rare snow to the city.
