Expect a good amount of sunny weather, punctuated by frequent afternoon rain showers and thunderstorms. Try to do your most active sightseeing as early as possible in the morning, before it becomes too hot and humid. On the hottest days (and rainy afternoons), indoor attractions such as museums or historic houses can provide a welcome relief from Savannah’s summer heat.

Pack light, loose clothing suitable for hot and sticky weather. It stays very warm well into the night, so there isn’t much need for outerwear at this time of the year. An umbrella is strongly advised during Savannah’s rainy summers, as are insect repellent and high-factor sunscreen.

Hurricanes are a possibility through August. You may wish to purchase appropriate insurance if you will be booking travel ahead of time. If a hurricane or storm hits during your stay, follow all local guidance and be prepared to evacuate if necessary.
