The 9 Best Things to Do in San Diego in September 2026

The last week of the Del Mar meet is the best week of it. Racing ends on Labor Day, so every card left is a closing card and the whole place knows it. Children 17 and under get in free, which makes this one of the few big San Diego days a family clears on a single adult admission. Buy the exact date rather than a generic ticket — days sell separately, and the final three go off earlier than the rest of the meet. Take the Labor Day card and let summer end properly.

Normal Heights hands over 10 city blocks and gets Southern California's largest free two-day music festival back. There are 7 stages running at once, 75 acts spread across them, 300 exhibitors along the sidewalks, and beer gardens and rides filling the gaps. Nobody buys a ticket to any of it. Saturday is the longer of the two days by 4 hours, which is why the avenue peaks somewhere around dinner, with every stage going at the same time and the whole street pointed at it.

Once a year the gates at MCAS Miramar open and the public walks onto a working Marine Corps air station. General admission is free, parking is free, and the flying list runs from the F-35B demo and the MV-22 Osprey through the ParaCommandos to the Blue Angels and Fat Albert closing it out. Anyone 18 or older needs government-issued ID at the gate, and non-U.S. citizens need documentation of legal status. Give it a full day. Nothing else in the county puts you this close to it.

8 days, more than 100 kitchens between Oceanside and Chula Vista, multi-course menus starting at $30, and no ticket to buy — you just book a table. The useful version of Restaurant Week is one reservation rather than five: find the kitchen whose set menu gives you more for the money than its regular menu would, and go there. Every menu is published in advance, which is the part most people skip. Read a few, pick the one you would still want on an ordinary Tuesday, and book it.

For one weekend at the end of September, Ski Beach turns into the center of San Diego's Pasifika community. The Pacific Islander Festival is in its 32nd year, a free celebration of Melanesian, Micronesian and Polynesian cultures held on Mission Bay, and there is nothing else like it on the county's calendar. The daily program lands closer to the date. Keep the weekend loose, walk in when the gates open, and give it the afternoon rather than an hour.

You climb into a barrel and stomp grapes with your bare feet. That is the event, and Menghini Winery runs it rain or shine on the first Saturday of the month. Admission covers the stomping, the entertainment, a glass you keep and, for anyone 21 or older, a tasting to put in it. Bring small bills, because the internet up there is spotty enough that card payments crawl. Bring a lawn chair too — this is a sit-on-the-grass afternoon, and the people who treat it that way get the best of it.

Unlimited hydroplanes take over Mission Bay for a weekend and make it the loudest water in the county. These are the fastest powerboats built, and they have been racing this bay since 1964. Three shorelines watch them — East Vacation Island, Crown Point and Fiesta Island — and each has its own event gate and its own approach off Sea World Drive, so the island you pick is the decision that shapes the day. Go for the boats. There is nothing in San Diego that sounds like them.

CRSSD puts a two-day electronic festival on the lawns of Waterfront Park at the end of September, outdoors and downtown. Chris Lake b2b Disclosure is the booking on this bill worth clearing a calendar for, and the rest of it runs deep enough — Mochakk, Groove Armada, Helena Hauff, Ben UFO — that your only real problem is set-time overlap. It is strictly 21 and over. Limited single-day tickets are on sale, which makes one day a genuine option instead of a whole weekend.
