The Bahamas & Turks & Caicos (The Bahamas, Turks & Caicos)
Early spring often delivers the best combination of calm seas and mild weather; March sees warming daytime highs into the mid‑20s°C (mid‑70s°F) and lots of dry, sunny mornings in the chain. Diving and snorkeling around the Andros banks, the Exumas and the Caicos reefs are excellent before the summer crowds; pack reef‑safe sunscreen and light layers for evenings. Book dive charters in advance as operators fill quickly.
Greater Antilles (Cuba, Jamaica, Hispaniola - Dominican Republic & Haiti, Puerto Rico, Cayman Islands)
March brings steadily warming days and low rainfall, perfect for exploring Santiago de Cuba, Santo Domingo’s Zona Colonial, or the Cayos near Cuba’s southern coast. Hikers tackling Pico Duarte or Jamaica’s inland trails will find dry, accessible conditions, but book accommodation early for spring break and festival periods. Sunscreen and a hat are essential as humidity begins to climb.
Leeward Islands (Northern Lesser Antilles: Anguilla, Antigua & Barbuda, St Kitts & Nevis, Montserrat, Guadeloupe and surrounding islets)
March often feels summery with warm days and low rainfall - ideal for hiking rainforest pockets in Guadeloupe or lounging on Antigua’s white sand beaches. Tourist traffic remains high as spring break season continues; expect busy harbors and full diving schedules. Bring reef‑safe sunscreen, and reserve inter‑island ferries ahead of time to avoid sold‑out crossings.
Windward Islands & Southern Lesser Antilles (Dominica, Martinique, St Lucia, St Vincent & the Grenadines, Grenada)
March in the southern Lesser Antilles is typically warm, mostly dry and excellent for outdoor pursuits: snorkeling around Tobago Cays, climbing Gros Piton or diving deep reefs in Martinique. Visitor numbers remain steady from winter sunseekers; book popular boat tours and dive slots early. Expect occasional trade‑wind gusts that cool the coast but make open‑water conditions choppier for small craft.
ABC Islands & Southern Caribbean Coast (Aruba, Bonaire, Curaçao, Trinidad & Tobago, Venezuelan islands and mainland nearby coast)
March sees stable, dry conditions across Aruba, Curaçao and Bonaire with warm seas and low rainfall - classic diving weather around Bonaire’s marine park. Trinidad and Tobago are warm and lively after Carnival, with good conditions for coastal hiking and birding on Tobago. These islands are generally less affected by Atlantic systems, but standard sun and water precautions still apply.
Western Caribbean & Central American Caribbean Coast (Yucatán Peninsula - Cancun, Cozumel, Tulum; Belize; Bay Islands of Honduras; Caribbean coasts of Guatemala, Nicaragua, Costa Rica, Panama)
March commonly feels hot and dry in the Yucatán and along the Caribbean coasts of Nicaragua and Costa Rica, making it one of the best months for beach time and archaeological sightseeing. Inland humidity is lower and hiking in Costa Rica’s Caribbean lowlands or the Rio Dulce area in Guatemala is very pleasant. Expect higher tourist numbers in coastal resort towns and book dive or reef excursions in advance.
