Field notes
Mild-warm year-round (10°C winter low to 28°C summer peak). Lowcountry humidity in summer is genuinely worse than the temperature suggests — June through September runs 75%+ daily. Hurricane season (June–November) is the recurring risk window. Spring (March–April) and October are the postcard windows.
