This isn't a shortlist. It's a weekend read on San Diego when the outlook sits near 77°F.
Should you plan around San Diego's forecast this weekend?
San Diego, California
Weekend air in San Diego sits near 77°F / 69°F, plus a dry outlook with little to no rain — enough to decide whether the trip is on.
Use the outlook as the itinerary filter: plan the outdoor pieces when 77°F feels right, and keep a café backup if clouds show up.
If the numbers still look good by Friday, lock the plan around 77°F — not a vague “nice weather somewhere.”
