Charleston’s Halloween forecast is mild but not exactly calm, with temperatures climbing from the low 60s into the mid-70s under partly sunny skies. Gusty northeast winds and dangerous surf will be the bigger story for anyone heading outside Saturday, October 31.
The latest outlook from the National Weather Service Charleston calls for a high near 75 degrees, northeast winds of 6 to 17 mph and gusts up to 25 mph. The update adds sharper beach and coastal concerns to the forecast detailed in earlier Hoodline coverage.
High Rip Current Risk Hits South Carolina Beaches
A high risk for rip currents is in effect from 8 a.m. through Saturday evening along South Carolina beaches. Swimmers should stay near a lifeguard, and anyone caught in a rip current should float, avoid swimming directly against it and signal for help if they cannot move toward shore.
The rougher water arrives as northeast winds strengthen through the day, making a beach outing riskier even with warm air overhead. The warning applies across the South Carolina coast, including Charleston County beaches.
Windy Afternoon Could Bring Minor Coastal Flooding
Charleston Harbor could see minor coastal flooding around the early-afternoon high tide, which is expected to peak near 12:58 p.m. Water levels may rise as gusty northeast winds push toward the coast, although a coastal flood advisory had not been issued in the forecast provided.
Saturday night will turn mostly cloudy with a low around 60 and northeast winds continuing at 12 to 17 mph. Sunday, November 1, stays mostly cloudy and breezy with a high near 73, while a slight chance of showers arrives late Sunday night.
Rain Chances Build Early Next Week
Monday, November 2, brings a 40% chance of rain showers and another mild high near 73. Shower chances ease to 20% Tuesday before increasing again Wednesday and Thursday, with Thursday also carrying a chance of thunderstorms.
For now, Halloween plans around Charleston should be rain-free but wind-aware: mild temperatures will work in favor of costumes, while beachgoers and boaters face the most significant weather-related hazards.
