Best Time to Visit Charleston

Thanks to its subtropical climate, Charleston is a great place to visit any time of the year. Weatherwise, spring and fall are a favourite due to the super pleasant and mild weather in these periods. Spring is a favourite for seeing the beautiful magnolia trees in their full bloom. Summers are hot and humid but a fantastic time to visit if you are after some splashing around in the warm Atlantic water. Fall, especially October, is the time to visit to avoid the crowd and get the best deals while winters are ideal for enjoying the mild weather outdoors.
