Wow, what a warm summer it's been. July started it off being the 4th warmest on record by average high temperature (2nd warmest by overall average temperature) and August picked up the baton and just kept going.

This August will finish up the 5th warmest on record by average high temperature at 79.5 degrees. It's a far cry from the record hottest August (83.7 degrees in 1967) but then again, second place was 80.3 so all years are a far cry from 1967.

So individually, the months were pretty impressive, but combined, it's even moreso.

The period from July 1 to August 31 will go down as the second-warmest on record by high temperature average at Sea-Tac Airport, where records go back to 1945.

The average was 80 degrees (79.95 to be exact). narrowly edging 1958 at an average high of 79.9 degrees.

The record is 80.2 degrees set in 1967, but that was mostly set by the super hot August as July that year was just a little warmer than normal. So as far as consistently warm goes, this year takes the cake.

And if you want to get an even more impressive stat: The two months go down as the warmest on record by average temperature (high+low/2) at 69.2 degrees. The record was 68.8 set in that toasty 1967 summer.

For this year, of the 62 days of the two months, 51 of them had sun for some of the day with 24 of them crystal clear. The two months also combined for 34 days at 80 or warmer (we're at 39 overall counting some in April and May.)

The month also rattled off a 36-day streak with high temperatures at 70 or warmer, fifth-longest on record (61 is the record in 2003.) That streak ended Saturday.

Ironically, both months will also go down wetter than normal, courtesy of a few thunderstorms and wayward storms that managed to cool off a couple of days, but certainly not many.

Long range models suggest some warming again toward the end of this week. Could September make it a hat trick?
