🌡 The weather here, in general
Charleston runs the full range. The warmest stretch, around July, averages a high near 85°F, while January nights average 28°F — a 57-degree spread, so a coat that works in January is useless by July and the other way round.
The thermometer rarely spikes — only about 11 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.
Snow shows up most years — about 16 inches — but rarely in quantity. 71 freezing nights a year matter more, because the risk here is ice rather than depth.
Rainfall averages about 52 inches a year, wettest in July and driest in November.
