What to expect in the worst months
August. Daytime highs averaging 35°C / 94°F mean outdoor sightseeing between roughly 11 a.m. and 4 p.m. becomes uncomfortable — locals retreat indoors and many smaller shops close in the afternoon. 14 rain days out of 31 means roughly 45% of days see measurable rainfall — plan flexible indoor backups for every outdoor day. This is peak hurricane season — disruptive weather can shut down flights, boats, and outdoor activities at short notice.
September. Highs in the 32°C range are tolerable in the shade but draining if you're walking all day. 14 rain days out of 30 means roughly 47% of days see measurable rainfall — plan flexible indoor backups for every outdoor day. This is peak hurricane season — disruptive weather can shut down flights, boats, and outdoor activities at short notice.
July. Daytime highs averaging 35°C / 95°F mean outdoor sightseeing between roughly 11 a.m. and 4 p.m. becomes uncomfortable — locals retreat indoors and many smaller shops close in the afternoon. 14 rain days out of 31 means roughly 45% of days see measurable rainfall — plan flexible indoor backups for every outdoor day.

- Wet: Real rain shell (not a "water-resistant" jacket), packable umbrella, dry-bag for electronics, quick-dry layers. Pre-book indoor museums and food halls.
- Storm season: Buy travel insurance with weather-disruption coverage, build 24–48 h flexibility into your itinerary, and follow the local meteorological agency on social.
