Johns Island, SC Overview

Unlike the majority of Lowcountry communities, Johns Island is one of the last bastions of the gracious old rural South.  Nevertheless, a few developers have managed to build residential communities that offer beautiful developments blending into pristine fields and marshland.  These homes are particularly attractive to retirees who appreciate the tranquility and simplicity of the island's slower pace.  At one time Johns Island produced the lion's share of the city's fruits and vegetables and farmers markets or roadside stands are still common sights.  The island's most famous landmark is the Angel Oak, estimated at 1,400 years old from a younger limb but possibly twice that age.  This massive 65-foot tree casts a 17,000-square-foot shadow, enough to shade the island's entire population. Newly constructed Stono River bridges connect the island to a more contemporary world and will undoubtedly drive deeper residential development.

Climate and Weather

The Temperature chart displays average high and low values for January and July, and is designed to provide an indication of both seasonal and daily temperature variability. The Weather Risk Index indicates the calculated risk of each type of weather event occurring in the future. This risk is based on historical localized storm events and weather patterns. The national average for each type of weather event equals a score of 100, so a score of 200 would represent twice the risk as the national average, and a score of 50 would represent half the risk of the national average.
