Hurricane season officially runs from June 1 to November 30, with the peak typically occurring from mid-August to late October. While the island has a good track record, it's essential for visitors during these months to stay informed about potential storm systems.

Staying Informed

Before and during your trip, monitor forecasts from reliable sources such as the National Hurricane Center (https://www.nhc.noaa.gov/) and local news outlets. Many hotels and rental properties have specific hurricane preparedness plans. Familiarize yourself with local evacuation routes and emergency procedures if a storm threatens.

Impact on Travel

Factors Influencing Local Weather

Several factors contribute to the unique St. Simons Island weather patterns you'll experience.

Proximity to the Atlantic Ocean

The ocean acts as a major temperature regulator. It prevents extreme temperature swings, leading to milder winters and less scorching summers compared to inland areas. The sea breeze also provides a cooling effect during warmer months.

Gulf Stream Influence

St. Simons Island is influenced by the Gulf Stream, a powerful ocean current that brings warmer waters northward. This contributes to the relatively mild winter temperatures experienced on the island.

Humidity and Dew Point

Due to its coastal location and warm temperatures, St. Simons Island often experiences high humidity. This can make the already warm temperatures feel even hotter. The dew point, which measures the actual amount of moisture in the air, is often high, especially during summer.

Planning Your Visit Based on Weather

Best Time for Budget Travelers

The shoulder seasons (Spring and Fall) can sometimes offer better deals on accommodations. The off-season (winter) will likely have the lowest rates, but you'll need to be prepared for cooler weather.
