What September feels like
September is the sneaky beach month — kids are back in school and the ocean is at its warmest. The catch is the first Santa Anas, which shove hot dry air all the way to the coast and put the whole basin on fire watch.
Rain is genuinely rare — most years, September stays dry start to finish. about 6 afternoons top 90°.
Can you swim?
The ocean runs about 69° — brisk but swimmable.
