Yes.
Both.
It is hot in the sun and cold in the shade because of the breeze.
And in the fall when the days are crystal clear and the humidity is extremely low, there are big intra day temperature swings. It can be 75-80 in the afternoon and 50 in the evening after the sun goes down.
And I forgot to mention the micro climates. A number of CA cities are ringed by mountains. Temperatures are mild at the beach, hot in the low inland valleys, and cool in the mountains. There is an inland valley in San Diego that grows oranges and avocados. Twenty miles further inland, the altitude is 4220 feet and they grow apples. It is like Florida and Washington state being 20 miles apart.
