Year-round weekly Tuesday street fair on Main Street — farmers market, food trucks, live music, beer garden, 4:30–8:30pm.

Surf City Nights is a year-round Tuesday-evening street fair in Downtown Huntington Beach where the first three blocks of Main Street — between Orange Avenue and Pacific Coast Highway — close to cars and fill with farmers market stalls, food vendors, craft booths, live music, kids activities, and a beer garden. It runs 4:30–8:30pm weekly.
It's the closest thing OC has to a weekly downtown block party. Three blocks of Main Street become walkable for fresh produce, food trucks, art and craft booths, and stages with live music, with the bars and restaurants on Main spilling out alongside. The format is more substantive than a typical farmers market — closer to a recurring small festival — and admission is free.
Held weekly Tuesdays year-round, 4:30–8:30pm. The closure runs Main Street from Orange Avenue down to Pacific Coast Highway. Free admission. Parking is in the downtown structures off Walnut Avenue or 5th Street — arrive before 5pm for easier spots, or walk in from the city beach lots. Most vendors accept cash and cards; the beer garden is 21+ with ID. Weather rarely cancels, but check the Downtown HB calendar before driving in.
Tuesday-night downtown means traffic and parking tighten as the closure starts — PCH backs up if you're rolling in at 5pm. Once the work crowd shows, the bar and restaurant side of Main runs loud; this is block-party energy, not a quiet stroll. Skip the closest pier-side lots and grab a spot near 5th Street or in one of the city structures, then walk in.
