June is the wet season proper and the southern swell at a useful size. The pattern is stable enough to plan on: the sky is clear at dawn, the wind is light, and the weather builds through the afternoon into something loud that clears by evening.
Anybody surfing here in the wet half of the year lives on that pattern. Two sessions before ten, a long lunch, and the sea again at five if the sky has finished with it. It is a better arrangement than it sounds, and it is why the wet season does not read as a warning here the way it does in Indonesia or Sri Lanka.
Santa Catalina is at its most reliable in this half of the year in terms of size, which is a different claim from the clean-day figure January carries. The road in is the thing to check: this is the season when the last stretch of it starts asking questions.
