A word on the weather. You may already know all this, but just in case…
In May and June, we have “May gray” and “June gloom.” It’s frequently cloudy in the mornings and at night. Sometimes all day. The further you go inland, the less cloud cover you’ll have.
Also, it’s pretty cool (temperature-wise) near the coast. If you like highs in the upper ’60s and low ’70s, right along the coast is good. Every mile you go inland makes a difference. In Carmel Valley (about 3 miles inland) it’s in the low ’70s almost every day in the summer. Which sounds really nice. And I guess it is. But I’ve found it a bit cool for my taste. And it’s cool every night (except a few nights during the strongest Santa Anas). Great sleeping weather, but you’ll need a jacket if you want to spend much time outside at night. Even in July and August. In Scripps Ranch and Poway (9-12 miles inland), it’ll be 6-15 degrees warmer than Carmel Valley, depending on the microclimate where you are. That usually varies depending on how much air flow you get from the ocean. The more seabreeze, the cooler, obviously. You’ll get less cloud cover out there, too.
The real beauty is you can pick exactly how warm you want it to be. La Jolla and Del Mar, Carmel Valley, Santa Luz (you might check that out) and Rancho Penasquitos, Scripps Ranch, Poway. Each of these is a bit warmer than the previous.
