When most people think of the Pacific Northwest and Western Washington, they
think of rain. On Lopez Island and the rest of the San Juans, it is somewhat of a different story.
Lopez actually gets about 247 days of sun a year.
The saltwater temperature around Lopez Island averages about 42 degrees in
the winter and 52 degrees in the summer. Lopez only gets close to about
half as much rain as Seattle does, mostly because the Olympics and Vancouver
Island push most winds up into cooler air and force them to dump their rain at a
higher elevation, but don't let that fool you, October through April can be very cold and wet.
The weather is usually moderate. Temperatures can
sometimes reach 80 degrees in the summer and will fall below 30 degrees in the
winter. Occasionally, Between December and January, there may be a little
dusting of snow, but don't worry, it is nothing that common or serious.
In the dry summer months and during September and early October, the islands can go for
weeks without a cloud in the sky. The Rainfall in the islands
averages 29 inches a year. Floods, high humidity, blizzards, extreme heat or
cold and other natural disasters are not heard of on Lopez.

the lowest is 8 degrees (January 1950).
