Savannah’s climate is shaped by its coastal location in the Deep South, resulting in pronounced seasonal contrasts. Summers (June–September) are hot, humid, and often feel tropical, with average highs of 32–34°C and lows around 22–24°C. Humidity is high, and the heat index can exceed 40°C during the hottest months. Afternoon thunderstorms are common, especially in July and August, which are also the wettest months, each receiving over 150–180 mm of rain. Despite the heat, sea breezes offer some relief, and long daylight hours provide plenty of time for outdoor activities.

Winters (December–February) are mild and brief, with average highs of 16°C and lows around 4°C. Frost is possible, and a few nights each year dip below freezing, but snow is extremely rare. Sunshine is abundant in winter, and rainfall is lower, especially in November and December, the driest months. Spring (March–May) and autumn (September–November) are transitional seasons, offering warm, pleasant weather, blooming gardens, and fewer crowds. Rain falls moderately year-round, with an annual total of about 1,220 mm. Winds are generally light to moderate (10–18 km/h), but can increase during storms. Savannah enjoys around 2,800–3,000 hours of sunshine annually, making it a bright and inviting destination for most of the year.
