What March feels like
March is when upwelling drags the coldest water of the year to the surface, so the sea is at its least inviting just as the air improves. On land it is the best hiking of the season, with creeks running in the front-country canyons.
Expect about 4 days with real rain — enough to notice, not enough to plan around. The air runs dry — whatever the thermometer says, it wears easy.
Can you swim?
The ocean runs about 55° — frigid — locals in wetsuits only.
