We had our hottest day of July on Sunday with Sea-Tac hitting 94, Olympia 95, and Shelton hitting a sweltering 98 degrees. We’ll be right back in that range Monday as our heat continues.
Our mean temperature so far this month is 70.5 degrees. The record of 71.2 was set in July 2015. In second place is August 1967 at 71.1.
It looks unlikely we will break the 2015 record now as our mean temperature is only going up about .2 or .3 degrees per day.
Official record-keeping at Sea-Tac dates back 73 years to 1945.

So far this month we have had about four times as many days with above average high temperatures as below average or average days.
After Sunday’s 94 at Sea-Tac, we have had seven days at 90 degrees or above which puts us in second place for the most 90-degree days in July. You probably recall that May this year was the warmest May ever recorded.
If it seems like we are setting a lot of records like this, you're right. Ten out of the 12 hottest months ever record have been since 2010. August and September of 1967 are the only outliers.
But relief is in sight! Onshore winds will begin to increase a little on Tuesday, dropping highs back into the mid to upper 80s. Wednesday will start with cloudy skies, but the sun returns quickly.
