Fog and overcast skies are common in the colder months, but the lush greenery reflects the abundance of rainfall.

The climate, paired with the forested landscape, creates year-round recreational appeal and high biodiversity in surrounding parks.

Historical Overview

The area now known as Issaquah was originally inhabited by the Duwamish and Snoqualmie Tribes, who thrived along the lakes and creeks of the region. The name “Issaquah” is believed to be derived from a Native American word meaning “sound of birds” or “snake.”

The city’s early European-American development in the late 1800s was centered on coal mining, logging, and later, farming. The Seattle, Lake Shore and Eastern Railway played a crucial role in transporting coal and timber, leading to population growth.

Incorporated in 1892, Issaquah remained a small town until the late 20th century. The city’s population surged in the 1990s and 2000s due to suburban expansion and its proximity to growing tech campuses.
