Summary
September 29, 2025, ushers in a transitional weather pattern shaped by Tropical Storm Imelda, steering northeast just off the Southeast U.S. coast. Coastal and marine conditions will dominate early in the week. Expect showers, thunderstorms, and freshening northeast winds that whip up significant surf and choppy seas. Inland areas west of I-95 have a chance to catch light rain but will progressively dry as high pressure advances.
By Wednesday and Thursday, a building high-pressure ridge will push drier, sunshine-filled days with moderate temperatures in the upper 70s to around 80°F. These days offer prime conditions for inland hiking and biking, as trail surfaces will be dry and winds manageable. Toward the weekend, the forecast sees increasing moisture returning from offshore troughs, bringing back showers and thunderstorms that could affect coastal excursions.

Adventure Recommendations
Coastal activities such as kayaking and paddleboarding are best postponed early in the week due to rough seas and gusty winds stirred by Tropical Storm Imelda. For inland adventurers, Tuesday afternoon through Thursday provide the best weather windows—clear skies, mild temperatures, and manageable winds make hiking in Francis Marion National Forest or exploring the ACE Basin more rewarding.
Beachgoers should remain vigilant: a High Risk of rip currents and High Surf Advisory remain effective through at least Wednesday, calling for responsible swimming choices. Coastal flood risk grows later in the week near Charleston and Colleton counties, particularly during high tide cycles.

- Gusty northeast winds up to 35 mph along the coast impact boating and beach safety
- High surf with waves 5+ feet, elevated rip current risk
- Minor coastal flooding possible during afternoon high tides starting Tuesday
- Slick and muddy trail sections during and after rain showers

Frequently Asked Questions
What areas are safest for outdoor activities during Tropical Storm Imelda's passage?
Inland areas west of I-95 offer lighter rainfall and less wind impact compared to the coast. Focus on trail activities away from flood-prone or exposed coastal zones, and avoid water sports until seas calm.
Are there any lesser-known spots for viewing coastal storms safely?
Lookouts at Folly Beach Pier provide strong viewpoints several hundred feet offshore but stay behind barriers. The Isle of Palms Connector Road provides elevated views with parking and access to other recreation.
What local wildlife might be spotted during fall hikes near Charleston?
Expect to see migrating songbirds like warblers, coastal marsh birds such as egrets, and possibly white-tailed deer venturing closer to trails during cooler weather.
How should I prepare for the high rip current risk at local beaches?
Heed all beach signage and lifeguard warnings, avoid swimming alone, and stay within designated swimming areas. High surf makes ocean swimming dangerous even for experienced swimmers.

Charleston’s historic plantation trails and Fort Sumter National Monument provide unique opportunities combining hiking, history, and photography.
