Weather & Natural Occurrences

Washington is called the Evergreen State for good reason…and it is green here because we do get a lot of rain. But we do not get as much rain as people who haven’t spent time here think. Our climate is mild. It seldom gets hotter than 90 degrees Fahrenheit (33 degrees Celsius) and in the warmer summer months we have our dry season, so it is not humid when it is warm. In the winter, we have very few days when the highs stay below 32 degrees Fahrenheit (0 degrees Celsius), so when we occasionally have snow, there isn’t much, and it doesn’t stay around for very long. Despite the rain during the winter, we seldom have electrical storms, so power outages caused by lightening are not frequent. We don’t get hurricanes. There have been four tornadoes in Thurston County since 1950 (three were EF-0, and one was an EF-1). Except for a small privately-owned beach on Puget Sound, nearly all of Lacey is more than 100 feet above sea level, so tsunamis, super tides, and raising sea levels should not cause disruptions in Lacey.

Volcanos–There are two currently inactive volcanos within 100 miles of Lacey. Mount Rainier, which has not erupted in more than 100 years, is located approximately 67 miles east southeast of Lacey. Mount St. Helens, which brought awareness to volcanos in the United States with its eruption in 1980, is located 99 miles south southeast of Lacey. Because the wind travels primarily from the west, neither has had much effect on the Lacey area. The State of Washington Department of Natural Resources has extensive information about volcanoes on its website which can be accessed by clicking here.

Earthquakes—Earthquakes can happen in many places throughout the United States, including western Washington. Extensive information on earthquakes is available from a number of sites including the Washington Department of Natural Resources, available by clicking here.
