April 5 in Fairwood sits right in that classic Pacific Northwest spring tension — expect something in between the 76° scorcher of 1966 and the 26° freeze of 1961, with nearly even odds (46%) of catching some rain. The average for the date is a mild 59° high and 39° low, which is pretty much exactly what spring should feel like.
Fairwood's weather has real range — from a brutal -10° in January 1950 to a historic 106° during the Pacific Northwest heat dome of June 2021, this isn't a place that plays it safe. The wettest single day on record dropped 6 inches in late December 1949, which says a lot about where the wild weather tends to come from.
If you're chasing warmth, late July is your window — the week of July 23–29 averages a high of 80°, while January bottoms out around 45°. Wet season peaks right at the holidays, with Christmas week averaging 1.6 inches of precipitation, so summer visits run notably drier than winter ones.
