Forecast

Duncan has a mild marine climate because it is near the Pacific Ocean. The ocean keeps winters from becoming very cold and summers from becoming too hot. The area usually has wet winters and much drier summers.

In fall and winter, low-pressure systems often move in from the Pacific. They bring clouds, rain, and strong winds. In summer, high pressure is more common. It brings more sunlight, lighter winds, and long dry periods. Spring and fall can change quickly, with a mix of rain and sunny days.

Duncan lies in the Cowichan Valley on the east side of Vancouver Island. Mountains help block some Pacific storms, so Duncan is often drier than places on the island’s west coast. The valley can also trap cool air on calm nights. Snow is uncommon and usually does not stay long, while summer droughts can increase the risk of dry grass and forest fires.
