Lake Wylie Humidity
6+ months
Above 70% RH annually
Tega Cay is a peninsula surrounded on three sides by Lake Wylie, and that proximity drives ambient humidity significantly higher than inland York County communities. Lake-adjacent homes experience slower structural drying after water events because the surrounding air is already moisture-laden. During summer months, relative humidity routinely exceeds 75% — and the lake's thermal mass keeps humidity elevated well into evening hours when inland areas begin to dry.
