It was a foregone conclusion with still a number of days left in the month that August was about to set Seattle's all-time record for hottest nights on record, all that was unknown was what number would be officially entered in the record book.
Grab your pencil: The number is 59.9 degrees, missing Seattle's first-ever month with a 60 degree low temperature average by 3 total degrees. (As in, had one night been 59 instead of 56 we would have had enough for a 60 average). The old record was 58.4 degrees (for Sea-Tac) which is remarkable because beating an record like a monthly average by a full 1.5 degrees is more of an obliteration than the Huskies did on Boise State Saturday.
As you might imagine, there were a number of other warm-night records that fell as well. August had an all-time monthly record 16 days with a low temperature at or warmer than 60 degrees at Sea-Tac. Old record? 11, set in July of 1994. (August 1942 did have 13 at the Downtown Federal Building.)
Guess how many 60+ lows we're *supposed* to have in August? Three. Average lows are in the mid 50s.
For the entire year, we are now at 25 days with a low of 60 or warmer through Sept. 1 (and Sept. 2 is on its way to being No. 26), already breaking the annual record with still potentially some warm weather still left in September. The old record was 18.
Annual average? Eight.
As I mentioned in my earlier blog leading up to the record, it's been the consistent pattern that has "graced" Seattle with much higher dew points this year. The muggy air keeps temperatures up at night and that has been the case time and time again.
Plenty of warmth in the daylight hours as well
The high temperatures weren't too shabby either. Overall, Seattle had an average high of 79.0, which is good for 6th warmest at Sea-Tac. However, in a testament to our consistent sunshine, but not searing heat, Seattle only had three days over 85, none over 90, and failed to set any record highs during the month.
Instead it was a whole lot of low 80s. 15 of the 31 days had highs in the 80s, so that is 12 days between 80 and 84. The "Seattle Summer Minutes" clock I keep track of for number of minutes at or above 80 at UW came in at 1,299 for August -- actually below the average of the past 13 years -- mainly due to lack of days in the low-mid 90s that really spike the counter. Seattle is on an impressive 30-day streak of high temperatures at 70 or warmer.
And for those keeping track of the 80s, Seattle is now up to 37 days this year including Monday. Normal is 25, but record is 47.
Long range models say we dip back down this week with another low pressure area about to keep showers and thunderstorms in the forecast for a while, but there is some potential for 80+ degree weather returning next week. Stay tuned to see if I need another similar blog at the end of September!
