Quick answer
Fall is the best time of year to be in San Diego. September and October bring the warmest ocean water of the year (around 68–72°F), the clearest skies after the summer marine layer breaks, and hotel rates that drop noticeably after Labor Day. The anchor events are Fleet Week and the MCAS Miramar Air Show in late September and early October, Día de los Muertos in Old Town at the start of November, San Diego Restaurant Week in the fall, and a dense Halloween calendar. November adds the Thanksgiving weekend lull, when the city is quiet and the weather is still in the high 60s. Book air show and Restaurant Week plans ahead; almost everything else is walk-up.

September
Warmest ocean of the year
Free
Water peaks around 68–72°F in late August and September, which is as warm as it gets here. Swimming, snorkeling at La Jolla Cove and kayaking are all at their best now, with far fewer people than July.
Fall Restaurant Week
Set-price menus
Two-course lunches and three-course dinners at fixed prices across hundreds of restaurants. The best way to try the expensive rooms; reservations open in advance and the top spots go fast.
October
MCAS Miramar Air Show
Free general admission · paid seating available
The largest military air show in the country, headlined by the Blue Angels. General admission is free, parking is the bottleneck, and the show runs most of the day. Bring ear protection for kids.
Local tip: Arrive early, bring sunscreen and a hat — there is almost no shade on the flight line.
Halloween in San Diego
Free to $60
Haunted houses, the Haunted Trail in Balboa Park, SeaWorld's Spooktacular and the Zoo's HalloweenFest for younger kids, plus adult parties in the Gaslamp and Pacific Beach.
Pumpkin patches and harvest festivals
$10–35
Bates Nut Farm in Valley Center is the big one, with a corn maze and pumpkin fields. Julian's apple season overlaps — pie, cider and a mountain drive an hour east.
November
Día de los Muertos in Old Town
Free · Nov 1–2
Old Town fills with altars, face painting, Aztec dancers and a candlelit procession through the historic cemetery. One of the most authentic free cultural events on the city's calendar.
Thanksgiving weekend
Varies
A genuinely quiet stretch: beaches empty, weather in the high 60s, and restaurants running prix-fixe Thanksgiving service. Book Thanksgiving dinner reservations several weeks out.
Holiday season kickoff
Late November
Seasonal ice rinks open, the Hotel del lights its tree, and neighborhood light displays start switching on in the last week of the month — before the December crowds arrive.
Fall planning notes
- • Dates for Fleet Week, the air show and Restaurant Week shift each year — confirm on the official sites.
- • Santa Ana winds can push inland temperatures into the 90s in October. Fire risk rises; check conditions before hiking east.
- • Hotel rates drop after Labor Day and stay low until Thanksgiving — the best value window of the year.
- • October daylight ends around 6:15 pm and November around 4:50 pm after the clock change; plan outdoor activities earlier.
- • The marine layer is largely gone by September, so this is the most reliable stretch for sunsets and clear coastal views.
