Stewart, BC, sits at the head of the Portland Canal in the Coast Mountains, delivering a cool, wet coastal climate. The live forecast above shows today’s conditions for this northern gateway, where winter snowpack is deep and summer remains mild and often drizzly.
What makes Stewart’s weather different from nearby towns?
Stewart’s position at sea level, surrounded by peaks, traps moisture from the Pacific. This creates far heavier snowfall than in Smithers, BC weather, which sits inland on the Bulkley Valley plateau. Stewart’s coastal influence also keeps winter temperatures milder than in Smithers, though the snow accumulation is much greater.
How much snow does Stewart typically get?
Stewart, BC snowfall averages around 300 to 400 centimetres annually, with the bulk falling between November and March. The town’s location at the end of the fjord funnels storm systems, so heavy snowfalls are common. For real-time views, a Stewart, BC weather cam at the harbour or highway junction shows current accumulation and visibility.
Can I see past weather records for Stewart?
Stewart, BC weather history is available from Environment and Climate Change Canada’s climate archive, which includes daily highs, lows, precipitation, and snow depth dating back decades. This data shows the consistent wet pattern and the rare cold snaps when arctic air spills over the mountains.
What is the best time of year to visit Stewart?
Late June through early September offers the mildest weather, with highs near 17°C and long daylight hours. Snow usually clears from lower trails by July, though rain remains frequent.
Does Stewart get more rain than snow in winter?
No, winter precipitation falls mostly as snow due to cold air trapped in the valley. Rain can mix in during warmer Pacific storms, but deep snowpack is the norm from December through March.
How does Stewart’s weather compare to Hyder, Alaska?
Hyder, just across the border, shares the same coastal-mountain climate. Conditions are nearly identical, though Stewart’s official records are kept by Canadian stations, while Hyder relies on US data.
