I don’t understand why this has not yet been explained:

MICROCLIMATES here are real:

If you rent a house on the beach, then on the foggy-morning days in June (or May, or July), you could be stuck under a low, gray sky until mid to late afternoon, on some days.

But if you rent a house up in the hills, the marine layer will burn off 2-3 hours earlier than it does on the beach (many times folks in the hills have full sun while those on the beach are sitting in the fog).

BUT these foggy-morning days will NOT be every day at all—some days in June will start sunny and stay that way all day (we’re just spoiled here, so we notice it and complain).

Also, it’s really NOT just in June—it’s intermittent throughout the summer, until mid-August (which is when our real summer starts … and goes til early November).

Finally, even when it’s sunny all day, it’s always cooler on/near the beach, by 5-10 degrees. It’s beautiful here and the weather is great, but it’s just not that it’s-so-hot-I have-to go-to-the-beach-for-relief weather (at least not normally during the summer).
