On average, Seattle gets about 25 days a year that go over 80 degrees. Ten of those days will go over 85 degrees.
Days that hit 90 or more are pretty rare, averaging just two per year, while a day over 95 occurs about once-every-other year.
Days where we hit triple digits are exceedingly rare -- about once every 35 years. The all-time record high for Seattle is 100 degrees, which it has hit only 3 times over the past 110 years records have been kept.
