Tide Tables and Weather on San Juan Island

The weather in the San Juan Islands is not the same weather you will find in Seattle. The Emerald City recieves approximately 30 inches of rain per year, but here in the islands, we receive approximately 18 inches per year. This is because we are located in the "banana belt" or the rain shadow of the Olympic Mountain range.  The locals also lovingly refer to this phenomena as "the blue hole", because on sunny days in our area, you can usually see the rain clouds off in the far distance. 

During the months of May - September the islands are generally sunny and warm and in the 70's, and year round we receive around 247 days of sunshine and about half the rainfall of Seattle.  Just west of here, the Olympic Rain Forest receives up to 250 inches per year.  In order to help you plan for your trip we've provided a few links to find out the weather you can expect while you're here.
