San Diego? D

Why do they even bother selling boots coats and umbrellas here??! I hate this. Has anyone heard that we could get ANY interesting weather aside from our day in day out sunshine down here? We used to in the 90’s!

Rain South Sacramento

Will South Sacramento get any rain in the 2018 winter season? Also, will the temperatures ever decrease? It is still in the mid-eighties here.

Rain wanted!!!


I'm dying for it to rain here in the SF Bay Area. I live on the Peninsula in East Palo Alto. I just want rain, I miss it so much and everything is getting so dry. This is my first time at this website. Do you all find that the weather predictions here are accurate? Like its says it will rain in No. CA in early to mid-November. Do you think my wish will come true???


RE: Rain Wanted

I am with you Susan. We live in Fremont and I am dying for some rain. I really do not like this warm/hot/humid weather we have right now going into November. I want the rain and the cold!
