It’s 100 degrees in The Mission today according to one of the weather stations of Weather Underground. (Weather.com says it’s “only” 92).

And if that turns out to be official, it stands to be the hottest day on record ever in San Francisco for September 8th, matching 100 degrees in 1984.

The Chronicle isn’t so sure, saying today tops out at 96 degrees, about 10 degrees shy of the all-time high.

The hottest it’s ever been in SF was 106 degrees which occurred on September 1, 2017.

And the longest heatwave was July 21-25, 2006 where the Bay Area experienced five straight days with at least one city cracking 110 degrees
