The day's biggest festival — free admission at the historic Sponge Docks, packed with local and regional seafood vendors, spices, small-business stalls and Greek-coastal flavor. 25 minutes up the corridor; it runs until 9 PM tonight, so you can skip the midday crush and go after dinner. Parking fills fast near Dodecanese Blvd — arrive by 6 PM or be ready to circle.
~100 vendors every Sunday on Corey Ave at St. Pete Beach — produce, baked goods, art, jewelry, plus food trucks doing breakfast through dessert. Weekly, year-round, so mark your calendar for next Sunday. Free parking at the library/City Hall lots, or roll in on the Sun Runner trolley.
All-ages community day at The James Museum: live music, dance, storytelling and art, with complimentary museum admission as part of the celebration. One of the best free family days on today's calendar — if you missed it, the museum's regular hours continue this week.
Great Explorations Children's Museum opened early with dimmed lights, soft music and a cool-down room for kids (and grown-ups) who need a quieter visit. Monthly program — details for the next one on the museum's site.
City-sponsored outdoor market at Campbell Park: locally made goods, vintage housewares, mid-century furniture, clothes, plants, food and music. One of only four Fall/Winter dates — this was it; the next is Sunday, Jan 3.
Teams of 2, 4 or 6 raced to finish puzzles fastest at Aspirations Winery in Clearwater — trophies, prizes, and every team keeps its puzzle. Wine and snacks for sale. A genuinely fun weird-fun day out if you're quick on jigsaws; watch for the next championship.
A new rock musical based on the true story of the Kashariyot — young Jewish women couriers who smuggled food, messages and weapons through Nazi-occupied Europe — performed inside the Florida Holocaust Museum. Small-venue intensity; check for upcoming weekend matinees.
The Gulf Coast's signature acoustic-country showcase — a roster of regional artists sharing one stage at the Mahaffey, trading songs and stories, all for charity (presented by the Kemp Law Group). Once-a-year Sunday-night lineup; doors-to-curtain is short, so head over now. Evening stays dry at a relaxed ~68–70°F.
Emo hits reimagined with a 14-piece orchestra — My Chemical Romance-to-Fall Out Boy territory with string sections — at the gorgeous Bilheimer Capitol Theatre in Clearwater. Nostalgia overload for anyone who owned a Hot Topic card in 2007; 25 minutes across the bridge.
Nashville indie-rock outfit on a marquee outdoor stop at Jannus Live's garden — their biggest St. Pete headline of the year. Sunday night on the lawn at a perfect 67°F with zero rain risk: bring a light layer for after sunset, and get there early — it's the late show of the night and Jannus lines move slow at 8.
