Moving from San Mateo to Fairmont (how much ☀️ ?)

We’ve lived in South San Mateo for 2.5 years and the weather is amazing. If I had to guess, I’d say the day ends with brilliant sunshine 300+ days a year. I love it!

We are bored, though, and eyeing Pacifica. How bad are the fog and the chill in Fairmont?

Can someone give me an estimate of how many days are completely grey and sun-free from dawn to dusk?
