Tybee Island in August is hot and humid with average high temperatures in the upper 80s, but the ocean breeze can make it bearable. While it’s a popular time for beach trips, visitor numbers tend to decline as the month progresses, especially on weekdays, with a resurgence for Labor Day weekend. You can expect warm, sunny days perfect for swimming, water sports, and enjoying the beach, though afternoon showers are common.
