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), Mount Pleasant shares the same real, humid subtropical seasonal pattern -- warm, not the drier heat of interior climates.
Hurricane season is a real, annual planning consideration
As detailed on insurance-hazard-costs, Mount Pleasant sits directly on Charleston Harbor with all 21 of its census tracts flagged for flood risk. Hurricane season (June through November) is a genuine, current annual planning consideration here, not a hypothetical or purely historical one -- Hurricane Hugo made landfall essentially at the town's doorstep in 1989.
Coastal humidity and sea breeze
Mount Pleasant's direct waterfront position along the Cooper River and Charleston Harbor brings real, consistent coastal humidity and sea breeze patterns, moderating summer heat somewhat compared to fully inland Lowcountry locations while adding to the area's real tropical-moisture exposure during storm season.
