Every fall in Northern California, the coastal zones get a taste of the torrid heat the interior zones have been sweating under all summer, and such an event is shaping up for this coming week. Highs will be well into the 90s, even in coastal areas, and just inland from the coastal hills the temps will be up around 110.
I have decidedly mixed feelings about this: on one hand, it is nice to be able to go to the beach and wear something lighter than a parka (I'm only slightly exaggerating): on the other, no one near the coast has air conditioning, so trying to drop off to sleep when the temperature in your apartment is 85 degrees is not much fun.
One thing nice about it is what it portends: fall heatwave = rainy season coming soon, which means green grass and new life. Sweet.
