Average annual precipitation at the Sitka Airport averages about 90 inches with most precipitation occurring as rain. In early and mid-summer the high pressure ridge tends to move north through southeast Alaska creating a relatively dry season. April through July receive 3 to 4 inches of rain per month. The high pressure moves back into the central Pacific the rest of the year, permitting storms to move into the Gulf of Alaska with stronger and more frequent frontal systems passing over southeast Alaska. The wettest months of the year are September through November, with October receiving an average of 14.8 inches (a Sitka November record of 19.67 inches was set in 2004).
The temperatures in the Sitka area are moderate, ranging from an average daily low of 31 degrees Fahrenheit in January to an average daily high of 55 degrees in July and August.
