The forecast is right.

The summer has been cooler than the last few years and we have had rain already early September. The weather has already changed to fall like weather, with more rain coming the middle of Sept. No heat wave this summer of 2019. Enjoy this early fall, No Indian summer.

March is the sole month without data representation, and we've having rain or showers five days out of seven. Why no forecast???

Number of Days it has rained

Does anyone know where I can find a comparison of the average number of days it rains versus the actual number of days it has rained? Example: November, 2018: 8 Rain Days on Average/XX Actual Rain Days. Thanks.

3 Years Drought Now This?

I think I might take back my wishes for rain!

Rain

Right??!! So agree! Enough already. Hard to be a beach bum with all this madness. I long for 90 to 100 degree heat!! Looove it.

The Rain in NorCal

Is such a drag!!! Gotta get our Sundance mojo going! This is too much! Makes me miss LA.

It never rains in the Bay Area in April

If it keeps raining in the Bay Area through April I am going to lose my mind. We have had nearly constant rain storms since mid-October. I really hope this forecast is wrong.

Frisco rain

I hope it continues to rain through June!!!

Rain in california

Im from san diego california. We need all the rain we can get. It would be nice if it rains all. Year round .

Yes!

Only people from SD get this, right!?
