Keep an umbrella handy today in Coquitlam as the live forecast above shows a wet pattern settling over the Tri-Cities, thanks to a Pacific frontal system pushing across the Coast Mountains and into the Fraser Valley.
What’s driving Coquitlam’s weather right now?
Coquitlam sits in the rain shadow of the Coast Mountains but still gets plenty of Pacific moisture when southwesterly flow funnels clouds and showers up Burrard Inlet and across Burnaby Mountain. The live forecast above reflects that onshore flow, with temperatures staying mild overnight due to the marine layer. Gusty winds may develop near Eagle Ridge and along the Coquitlam River corridor, so secure loose yard items if you live in those exposed areas.
How does this compare to seasonal norms for late March?
Coquitlam typically sees daytime highs near 12°C in late March and about 120 mm of rain for the whole month. The live forecast above shows near-normal temperatures, though the frequency of showers is a bit higher than usual this week. Snow levels remain above the local ski hills, so no accumulation is expected in the city itself. Gardeners should wait a few more days before planting tender annuals as soil temperatures are still cool.
Does Coquitlam get more rain than Vancouver?
Not generally. Coquitlam is slightly inland and east of Vancouver, catching some extra orographic lift from the mountains. Yearly precipitation totals are similar — about 1,200 mm — but Coquitlam sees a bit more in spring and autumn.
Why does it feel cooler in Coquitlam compared to downtown Vancouver?
Coquitlam is farther from the ocean’s moderating influence and sits at a slightly higher elevation. On clear nights, cold air drains off Eagle Mountain, leading to frost in low-lying neighbourhoods like the upper portions of the Burquitlam area.
When does the dry season typically start in Coquitlam?
The driest months are July and August, with July averaging only about 35 mm of rain. The shift from wet to dry usually happens in early June, once the Pacific high-pressure ridge strengthens and shunts storms north of the region.
