What & Why

The San Juan Island Microclimate

The San Juan Islands enjoy a unique microclimate shaped by their proximity to the Pacific Ocean and the Olympic Mountains. This results in milder temperatures compared to the mainland, with less extreme heat in the summer and less severe cold in the winter. The islands also experience a phenomenon known as a "rain shadow," where the Olympic Mountains block much of the incoming weather systems, leading to less rainfall than other areas of Western Washington. — UPS Shipping Labels: How To Create & Print Online
