A wet forecast doesn't ruin a Charleston trip. Here's what's worth doing indoors, and which tours carry on in the rain.
Short answer: book a food tour, the one tour that's better in the rain because you spend it inside restaurants. Otherwise pivot to the museums (the Charleston Museum, the Gibbes, the International African American Museum), the covered City Market, or a distillery or bar tour. And don't cancel your walking or ghost tour for a drizzle, most run with umbrellas.
Both keep you mostly indoors, with free cancellation if the forecast turns ugly.
A food tour is the rare tour that gets better in the rain, because you spend it inside warm restaurants eating, not out in the weather. You move between covered stops, so a gray day barely registers.

Historic bars and speakeasies, with the storytelling that connects them to Charleston's past. You're indoors between short walks, so it holds up fine when the weather doesn't.

The Charleston Museum, founded in 1773 and the oldest in the country, covers local natural and cultural history. The Gibbes Museum of Art focuses on Lowcountry art across three centuries. Most affecting of all is the International African American Museum, built on Gadsden's Wharf where tens of thousands of enslaved Africans first landed, with exhibits that reframe the rest of what you see in the city.
For families, the South Carolina Aquarium and its sea turtle hospital is the easy call, and older kids can clamber over the USS Yorktown aircraft carrier at Patriots Point, much of it under cover. When you just need to wait out a passing shower, the covered City Market is free and central.
Save the plantations, the beaches, and any boat tour for a clearer day. Plantation grounds turn to mud, beach days need no explanation, and harbor cruises lose their whole appeal under low gray cloud (and are the most likely to be canceled outright). Hold those, and lean into the indoor city instead.
Quite a lot, because much of Charleston is indoors anyway. A food tour is the best option, since you spend it inside restaurants. Beyond that: the Charleston Museum and the Gibbes Museum of Art, the International African American Museum, the USS Yorktown at Patriots Point, the South Carolina Aquarium, and browsing the covered City Market. Distillery and bar tours keep you indoors and lively. And most walking and ghost tours continue in light rain with umbrellas.
Most do in light rain. Walking and ghost tours carry on with umbrellas, and guides will tell you the atmosphere on a misty night arguably improves. Food tours run rain or shine since you're moving between covered restaurants. Boat tours and outdoor activities are the ones most likely to be rescheduled for heavy rain or storms, and operators usually offer a refund or a new date.
The South Carolina Aquarium is the top pick, with its sea turtle rehabilitation. The Children's Museum of the Lowcountry is built for younger kids, and the USS Yorktown at Patriots Point lets older kids explore a real aircraft carrier mostly under cover. The covered City Market is an easy, free stop to wait out a passing shower.
The Charleston Museum (the oldest museum in the country) for local history, the Gibbes Museum of Art for Lowcountry art, and the International African American Museum, built on the wharf where many enslaved Africans first landed, for the most moving exhibits in the city. Any one of them fills a couple of rainy hours well.
