If you're deciding on San Diego for 2026-10-03 – 2026-10-04, start with the numbers, then the plan.
What's the weekend looking like in San Diego?
San Diego, California
Weekend air in San Diego sits near 83°F / 70°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 83°F feels right, and keep a café backup if clouds show up.
If the numbers still look good by Friday, lock the plan around 83°F — not a vague “nice weather somewhere.”

Go if the outlook still matches what you want. San Diego is the trip — not a shortlist to compare.
Keep planning
