Tybee Island is near the Atlantic Ocean, where warm air rises, creating low air pressure. The island's flat geography allows winds to easily move and mix air, keeping it relatively stable.
In summer, the warm ocean water heats the air, making it rise, and causing low pressure. This brings hot and humid weather.
In winter, the opposite happens, and the cooler ocean water cools the air, making it sink, and causing high pressure. This brings cooler and drier weather.
Tybee Island has a humid subtropical climate. The climate's pressure patterns bring mild winters and hot, humid summers. The pressure changes also create a distinct difference between winter and summer.
