Just how often does it get this hot around here?

Just how often does it get this hot around here?
Thursday will likely mark our fourth consecutive day over 80 degrees, and third over 85. But it rarely gets this hot around here, right?

The statistics would say yes.

Seattle averages about 25 days a year at 80 degrees or hotter. Of those, about 10 are 85 or warmer and two are 90 and above.

Seattle has hit 100 once, on July 20, 1994, but we average a day at 95 or hotter about once every other year. Seattle/Sea-Tac has hit 99 twice, and 98 five times, including just two years ago. The Federal Building, which kept records from 1891-1972, has hit 100 twice, and 98 three times.

The longest streak of days at 90 degrees or hotter was 5 days between Aug. 7 and Aug. 11 in 1981.

However, 1977's streak might be more impressive overall. Even though it ranks No. 2 on the 90+ list at 4 straight days (Aug. 9 to Aug. 12), it ranks No. 1 for days 80 and above with 15 straight -- between Jul. 30 and Aug. 13.

So for those who like it cool, take solace in the fact that extended heat waves are quite rare and we've apparently already used up 30% of our 85+ days :)

By the way, if you want *really* hot, pity the poor folks down in Marble Bar in W. Australia, where they hold a world record for 162 straight days above 100 degrees from Oct. 30, 1923 to Apr. 7, 1924 (don't forget, their seasons are reversed). I guess there, you just throw a few shrimp on the sidewalk :)
