What October feels like
October keeps the beach going while the light softens and the tourist season empties out. Santa Ana winds show up a few times, hot and dry off the desert, and they bring fire weather with them — locals watch the ridgelines.
Real rain shows up maybe one day all month; the rest stay dry. Humidity stays comfortable; the air never feels heavy.
Can you swim?
The ocean runs about 65° — brisk but swimmable.
