Boy or Girl it's been a warm Fall

4. There is a time in Early October

where the natural air conditioner shuts down.

The inland valleys (the Big Valley) heat up in the summertime, hot air rises... and cool ocean air rushes through the golden gate and spreads across the bay... which is why you can identify the tourists in San Francisco in July and August... they are the ones wearing T-shirts and shorts, the natives are in layers including a hoodie.

But in October, the inland valley quits heating up so much, which shuts down the prevailing pacific breeze, and for a brief few weeks, the Bay Area can get quite warm.
