What August feels like
August is peak visitor season and peak marine layer, which is the peninsula's running joke. Car Week fills Monterey and Carmel in the middle of the month; the roads go slow and the hotel rates double.
Rain is genuinely rare — most years, August stays dry start to finish.
Can you swim?
The ocean runs about 61° — cold — a quick dip takes resolve.
