It's Comic Con week, and the closer to the coast is where you'll probably want to be.
We are just starting a warm up that will go through the end of the weekend. Already, Lindbergh Field hit 79 on Monday. Temperatures will warm a little each day through Friday. So, expect low 80s at the coast, and mid 90s inland by a little later in the week.
That monsoonal flow should stay away this week. So, while it will be pretty warm, at least it won't be too humid.
May our forecast be with you.
