What May feels like
May is when the microclimates go extreme: the Mission can be twenty minutes of sun away from a fogged-in Sunset. Bay to Breakers takes over the city late in the month, and the route runs through both climates.
Real rain shows up about 2 days all month; the rest stay dry.
Can you swim?
The ocean runs about 57° — frigid — locals in wetsuits only.
