If I were leaving San Diego Friday afternoon, I'd look at Boise (73°F) first.
The question
Where near San Diego has 70°F weather this weekend?
Weekend comparison

Where to go
1. Boise, Idaho
Boise in Idaho is one of the clearer matches for mid-70s sweet-spot weekends on this weekend’s board — a 73°F high and 48°F low with only light rain on the books (~0.06 in).
This is the kind of city stop you discover when you stop browsing generic guides and start asking for weather-perfect weekends. You can actually plan a trip around outdoor time here without pretending the sky will cooperate out of kindness.
If you’re comparing two or three towns, weigh Boise’s 73°F high against how you actually want to feel outside — then lock the plan once it feels like weather you’ll love.

Rank 2 isn’t a trophy — it’s a forecast fit. San Luis Obispo (California) lands near 74°F with a dry outlook with little to no rain, which is exactly the band people want for Goldilocks weather.
