Field notes
Tropical Caribbean — Saint Lucia's rugged volcanic geography produces meaningful microclimate variance; the windward east coast gets significantly more rainfall than Castries on the lee side. Dry season (December–April) is the postcard window. Wet season (May–November) brings afternoon thunderstorms and overlaps hurricane season; the island sits in the main Atlantic track. Trade winds keep the heat workable year-round (26–28°C). Humidity peaks above 78% in late summer.
