Field notes
Trade winds (the alisios) keep the heat workable year-round (25–28°C). Hurricane season (June–November) is the structural risk — Maria (2017) and Fiona (2022) are the recent serious reminders. Dry season (December–April) is the postcard window with reliable sun. Summer (May–October) brings afternoon thunderstorms but rarely all-day rain. Microclimate split: the north coast (San Juan) is wetter than the south.
