Why this weekend
2026-08-09 – 2026-08-16 is a short planning window for San Diego: enough forecast confidence to decide, not so far out that the outlook is fiction.
San Diego, California
Weekend air in San Diego sits near 78°F / 70°F, plus only light rain on the books (~0.08 in) — enough to decide whether the trip is on.
Use the outlook as the itinerary filter: plan the outdoor pieces when 78°F feels right, and keep a café backup if clouds show up.
If the numbers still look good by Friday, lock the plan around 78°F — not a vague “nice weather somewhere.”
