Atlantic Hurricane Outlook – August 31, 2025

On August 31, the Atlantic remains storm-free following the dissipation of Fernand and Erin’s exit. The only feature of interest is a tropical wave moving off Africa, with a low 30% development chance over the next 7 days. Environmental conditions—wind shear, dry air, and Saharan dust—continue to limit storm formation. Florida and the Gulf remain calm aside from typical summer storms.

Atlantic basin remains quiet; a weak wave off Africa shows low (30%) development odds

Atlantic Basin Overview

  • No Active Storms
    There are currently no active tropical cyclones in the Atlantic basin. The calm continues following Fernand’s dissipation and the end of Erin’s impacts.

  • Tropical Wave Near Africa
    A tropical wave is forecast to emerge off the west coast of Africa, and the NHC assigns it a low – but not negligible – chance of development: 0% over the next 2 days, increasing to 30% over the next 3 to 7 days.

Environmental Conditions

  • Sea Surface Temperatures (SSTs): Warm in the Caribbean and Gulf (~29–31 °C), but less favorable conditions in much of the open Atlantic.

  • Wind Shear: Continues to be elevated across large swaths of the basin, discouraging storm formation.

  • Mid-Level Humidity & SAL: Dry air and Saharan dust (SAL) remain prevalent, further suppressing convective activity.

Gulf of Mexico & Caribbean

The Gulf remains quiet and stable, dominated by high pressure. Only routine afternoon thunderstorms are occurring along the coasts—no tropical development is expected.

Florida & Southeast U.S. Forecast

Florida continues in its late-August pattern—hot, humid, with scattered afternoon thunderstorms. No tropical threats are present.

Beaches along the Atlantic coast are beginning to calm. With no new swells incoming, rip currents and surf conditions are generally improving, though caution remains prudent in areas still unsettled from earlier systems.
