Climate

Like the rest of the Salish Sea and surrounding regions, the climate of the Strait is disputed, with the Köppen system classifying it as

The dispute is only over the seaward boundary extending west from the mouth of the strait. The maritime boundary within the strait is not in dispute. Both governments have proposed a boundary based on the principle of equidistance, but with different basepoint selections, resulting in small differences in the line. Resolution of the issue should be simple, but has been hindered because it might influence other unresolved maritime boundary issues between Canada and the United States. In addition, the government of British Columbia has rejected both equidistant proposals, instead arguing that the Juan de Fuca

They also socialize with and encounter the local, non-migratory gray whales in the Strait; from a conservation standpoint, this is vital for the whales' ability to meet potential new mates, form new bonds, and ultimately create new bloodlines. This yearly influx of whales is best observed between March and May, at the peak of the migration times.
