Summer: Sun-Soaked Days and Coastal Living

Summer on Kiawah Island, from June through August, brings warm temperatures, abundant sunshine, and a lively island atmosphere. Daily highs typically range from the mid-80s to low 90s, while evening temperatures remain comfortably in the 70s. Coastal breezes and shaded trails help mitigate the heat, especially in the early morning and late afternoon hours.

This is peak beach season, drawing families, vacationers, and seasonal residents to the island’s shores. The Atlantic Ocean reaches inviting temperatures in the 80s, making water-based activities like swimming, paddleboarding, and boating especially popular.

Summer also brings the highest humidity levels and the most rainfall, primarily in the form of afternoon thunderstorms.

September begins with lingering summer warmth, with highs in the 80s, but temperatures gradually cool to the low 70s by November.

Humidity levels drop significantly as the season progresses, and rainfall becomes less frequent. The result is a crisp, clear atmosphere ideal for enjoying the island’s many golf courses, nature trails, and beach walks. Fall sunsets on Kiawah Island are particularly stunning, casting golden light over marshlands and coastal dunes.

This quieter season provides an excellent opportunity for prospective buyers to explore Kiawah Island homes for sale without the busyness of the summer crowds.
