Representative figures from each country's largest city. High / low are average daily temperatures (°C); “Feels” allows for humidity.
The Bahamas & Turks & Caicos (The Bahamas, Turks & Caicos)
By July the humidity is pronounced and afternoons can produce quick tropical downpours; daytime highs typically sit in the upper 20s to low 30s°C. Providenciales and the northern Bahamas feel sticky and quieter as families time travel for summer vacations; itineraries that depend on calm seas (like small‑boat hop) can be disrupted by squalls. Lightweight rainwear and a waterproof bag for electronics are useful.
Greater Antilles (Cuba, Jamaica, Hispaniola - Dominican Republic & Haiti, Puerto Rico, Cayman Islands)
July brings hot, humid days and lively beach culture, especially in Jamaican resorts, Cuban cayos and Puerto Rico’s north coast. This is festival and high‑season summer for many families; prepare for full hotels and higher prices. The mountains can provide cooler respite - Kingston’s Blue Mountains and Pico Duarte have noticeably lower temperatures - so include an inland escape if you need relief.
Leeward Islands (Northern Lesser Antilles: Anguilla, Antigua & Barbuda, St Kitts & Nevis, Montserrat, Guadeloupe and surrounding islets)
July is hot and humid with frequent brief downpours; beach days are still plentiful but midday storms can interrupt plans and make small‑boat trips bumpy. Festive summer events and regattas attract regional visitors while many hotels offer discounted summer packages. Bring quick‑dry gear, mosquito repellent and a reliable way to get weather updates while on smaller islands.
Windward Islands & Southern Lesser Antilles (Dominica, Martinique, St Lucia, St Vincent & the Grenadines, Grenada)
July is hot and humid and while large storms are possible, many days still feature long sunny stretches and calm sea conditions between squalls. Dive operators and sailing charters may run slightly reduced schedules or reposition for safety during periods of unsettled weather. If you plan to trek interior mountains, early mornings are best to avoid afternoon cloud build‑up and rain.
ABC Islands & Southern Caribbean Coast (Aruba, Bonaire, Curaçao, Trinidad & Tobago, Venezuelan islands and mainland nearby coast)
July is hot and humid across Trinidad & Tobago, with frequent short showers but many sunny intervals; the ABC islands remain comparatively dry and windier, often providing comfortable conditions despite higher temperatures. Summer is quieter for tourists on the southern islands, so you can secure affordable dive charters and quieter beaches. Stay hydrated and plan reef trips in the morning for best water clarity.
Western Caribbean & Central American Caribbean Coast (Yucatán Peninsula - Cancun, Cozumel, Tulum; Belize; Bay Islands of Honduras; Caribbean coasts of Guatemala, Nicaragua, Costa Rica, Panama)
July is hot and humid with frequent afternoon downpours and potential tropical disturbances; the Bay Islands and Belize are still popular with divers but expect more variable visibility and short interruptions. Off‑season travel means generally lower rates and fewer crowds at ruins and reserves, though services may operate reduced schedules. Bring waterproof gear for excursions and be prepared for insect activity after rains.
