Though the weather report says 90 today along the coast:

 Right now at around noon on Tuesday it is instead around 77 degrees where I live along the coast. Though the weather report right now from Google says this is as high as it's going to get I find it hard to believe it because we still have the whole afternoon to warm up further. I live in the Greater SF Bay area along the coast of California at the beach.

today's predicted Highs

Morgan Hill 104

Redding 103

Santa Rosa 103

Paso Robles 104

San Francisco 90

90 is a temperature in San Francisco you are likely only going to see once or twice in a year and usually in the fall right now where there are offshore breezes blowing winds from the inland out to sea.

Normally the winds are blowing from the ocean onto the lands which keeps the temperatures down pretty much all summer in the SF Bay area especially from about June to September.

Or as Mark Twain once said, "The coldest winter I ever spent was a summer in San Francisco".
