Six months of wet, six months of dry. That is California weather.
Here it gets down to 48 or 49 at night during the winter. The days are 51-53 degrees with rain. Some years there is more rain than others.
The summer is 51-60 degrees, with afternoon "breezes." It is BONE dry during the summer.
Winds (They call them trade winds for some reason.) every afternoon at about 3:00 P.M. The winds stop at sunset.
If you are out at the beach you can see the bank of fog MILES and MILES westward and you know that it will come blowing howling in about 3:00 in the afternoon. It's no surprise. A hooded, zippered, pocketed sweatshirt will do ya.
I have traveled the world quite a bit and except for New Zealand I have never seen any place as beautiful as the west coast of the US, but I can promise you, inspite of the weather, I will never come to San Fran again. Because my husband's nut case relatives might catch wind of it and if I NEVER see those insane people again I'll be happy.
