What April feels like
April is the shoulder locals like — rain that mostly comes overnight, wildflowers on the Marin Headlands, and the fog not yet in charge. Dress for the wind through the Gate rather than the temperature.
Expect about 4 days with real rain — enough to notice, not enough to plan around.
Can you swim?
The ocean runs about 56° — frigid — locals in wetsuits only.
