"The coldest winter I ever saw was the summer I spent in San Francisco." 

Whether Mark Twain said this or not has been hotly debated. But what is not under debate right now is how hot it’s been in San Francisco, debunking this famous quote.

According to the National Weather Service, San Francisco has seen the fifth hottest three-day streak in in history, a city where the average temperatures this time of year are usually in the mid-60s, not high 90s.

In fact, at 5 a.m. on Wednesday temps were a balmy 74 degrees, and the mercury has reached above 90 degrees every day since Sunday, something that’s happened only 13 times on record, according to the weather service.

Other Bay Area cities have broken or met records too, some that were set 115 years ago. 

They include: 

* Santa Cruz hit 95 degrees on Tuesday, breaking the previous record of 93 degrees set in 1904.

* Santa Rosa reached 100 degrees, breaking the previous record of 96 degrees set in 1945.

* Richmond reached 100 degrees, breaking the previous record of 91 degrees set in 2008. 

* San Jose reached 99 degrees, breaking the previous record of 98 degrees set in 1904.

* San Francisco airport reached 98 degrees, breaking the previous record of 88 degrees set in 1985. 

* Oakland reached 98 degrees, breaking the previous record of 85 degrees set in 2008. 

Wednesday's forecast shows hot weather throughout the Bay Area, albeit a few degrees cooler than the last few days. The fog is expected to roll in by Thursday.
