San Juan Islands Today

Today, the San Juan Islands are an important tourist destination, with sea kayaking and orca whale-watching by boat or air tours, two of the primary attractions.

Politically, the San Juan Islands comprise, by definition, San Juan County, Washington.

There are 172 islands in the archipelago, some little more than rocks, and over 300 miles (480 km) of shoreline. The majority of the San Juan Islands are quite hilly with some flat areas and valleys, often quite fertile, in between. The tallest peak is Mount Constitution, on Orcas Island, at almost exactly a half-mile (800 m) elevation. The coastlines are a mix of sandy and rocky beaches, shallow and deep harbors, placid and reef-studded bays. Gnarled, ochre-colored madrona trees (Arbutus) grace much of the shorelines while evergreen fir and pine forests cover large inland areas.

The San Juan Islands get less rainfall than Seattle, about 65 miles (105 km) to the south, due to their location in the rain shadow of Olympic Mountains to the southwest. Summertime high temperatures are around 70 °F (21 °C) while average wintertime lows are in the high thirties and low forties. Snow is infrequent in winter except for the higher elevations, but the islands are subject to high winds at times—those from the northeast sometimes bring brief periods of freezing and Arctic-like wind chills.
