Check the live forecast above before heading out, then plan for the day’s most likely conditions. Near Coquitlam, BC, weather is shaped by the nearby Coast Mountains and the Fraser Valley, making it cooler and wetter than downtown Vancouver.
What is the typical weather near Coquitlam?
The area experiences a temperate oceanic climate with mild, rainy winters and warm, dry summers. Winter temperatures hover near 0°C to 6°C, while summer highs reach the low 20s°C. Rainfall is heaviest from November to March, and snow can accumulate at higher elevations but rarely lasts long in the valley.
How does the geography affect local conditions?
Coquitlam sits at the foot of the Coast Mountains, so orographic lift often increases cloud and precipitation compared to Vancouver proper. The nearby Fraser River and Burrard Inlet also contribute to fog and cooler breezes, especially in spring and autumn. This makes it common for Coquitlam to see rain or drizzle when other parts of Metro Vancouver are partly sunny.
Does Coquitlam get more rain than Vancouver?
Yes, typically 10–20% more. The mountains force moist air upward, causing heavier and more frequent showers. Coquitlam’s annual average is about 1,250 mm, vs. Vancouver’s 1,170 mm.
When is the best time to visit Coquitlam for sunny weather?
July through September are driest and warmest, with average highs in the low 20s°C. Even then, afternoon clouds or a light sea breeze can appear, but overall conditions are ideal for outdoor activities.
Can snow cause travel disruptions near Coquitlam?
Snowfall is infrequent in the valley (about 5–10 days per year), but when it occurs, it can affect Highway 1 and local roads. Higher routes like the Coquihalla Highway may see significant snow even when Coquitlam stays mild.
