Consistent with the broader Charleston-area climate documented in charleston-sc.js (July highs near 90°F, roughly 72% average annual humidity, winter lows/highs commonly in the 43-57°F range), North Charleston shares this same real, humid subtropical seasonal pattern.
Hurricane season is a real regional planning consideration
North Charleston sits within Charleston-area mandatory-evacuation coastal-county zones and shares the region's Hurricane Hugo (1989) baseline exposure, even with its somewhat greater setback from the open barrier-island coastline than Mount Pleasant -- hurricane season (June-November) remains a real, current annual planning consideration.
A tri-county climate footprint
Because North Charleston genuinely spans Charleston, Berkeley, and Dorchester Counties, very localized weather conditions (drainage, flash-flood risk from heavy rainfall) can vary by which part of the city a specific address sits in -- confirm specific flood/drainage history for a target address rather than relying on a citywide summary alone.
