🌡 The weather here, in general

Charleston has four clear seasons. July highs average 88°F and January lows average 44°F.

The thermometer rarely spikes — only about 17 days a year top 90°F — but it hardly needs to. Summer sits in the mid-eighties for months at a stretch, and with humidity on top of it the heat index runs well above what the air temperature suggests.

Rainfall averages about 52 inches a year, wettest in August and driest in March.
