What it means for you
Whether you're thinking of moving, gardening or travelling.
🏠 Living here
Hot, sticky summers and mild winters — air conditioning runs hard from late spring to early autumn. Storm season needs preparation in coastal areas.
🌱 Gardening
Warm-season grasses and broad-leaved evergreens thrive; gardens are productive but humidity brings fungal pressure. Frost is occasional, so tender perennials often overwinter.
✈️ Travel
Spring and autumn are pleasant; summer is hot and humid; winter is mild and a fine alternative to escaping cold further north.
