What March feels like
The rains taper and the wildflowers start in the backcountry east of town. March also brings spring break traffic to Mission Beach and Pacific Beach; midweek is a completely different city than Saturday.
Expect about 3 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 59° — cold — a quick dip takes resolve.
