Trinidad and Tobago in March: Weather, Crowds & What to Expect

Northern Trinidad - Port of Spain & the Northern Range

Late dry-season mornings in March are excellent for birdwatching at Asa Wright and the cooler cloud forest, where hummingbirds are active before the heavier rains. Afternoon thunderstorms begin to appear more often by month-end; expect quick, intense showers in the plains that clear fast. For travelers, this is a good balance: fewer mosquitoes than in the wet months, good trail conditions, and still plenty of city events to enjoy.

Central Trinidad & Caroni Lowlands (Chaguanas, Arima, Caroni Swamp)

By March, intermittent showers punctuate otherwise hot days across the central plains; this is still part of the drier window so river levels in Caroni remain manageable for swamp tours. Roadside fruit stalls - mangoes and seasonal soursop - become more prominent, and early nesting activity can be seen among coastal birds. Travelers should pack insect repellent for dusk and plan swamp trips in the cooler mornings.

Southern & Western Trinidad - San Fernando, La Brea & Gulf of Paria

Warmth and increased humidity mark March, but afternoon clouds start to build more often, especially inland from the Gulf. Roadside bakeries and crepe stalls are lively as locals move between rehearsals and small-town carnivals; it’s a good month for visiting La Brea and the Pitch Lake when dust is low. Bring insect repellent and a hat for midday sun, and keep plans flexible for sudden showers.

East Coast & Windward Coast - Toco, Manzanilla, Grande Riviere

March usually signals the early nesting window for leatherback turtles - volunteers and conservation groups are active around Grande Riviere and Toco. Daytime temperatures are hot and humid, and brief but heavy afternoon showers become more common as the region moves toward its wet season. For travelers, witnessing nesting requires booking in advance and following strict conservation rules; expect rustic accommodation options near nesting beaches.

Tobago - Southwest & Leeward Beaches (Scarborough, Crown Point, Pigeon Point, Buccoo)

March offers languid, warm days and improved underwater visibility as the dry season continues, making it one of the best months for diving and snorkeling off Speyside and Buccoo. Whale- and dolphin-watching trips operate well from the southwest coast, where calmer seas make sightings more comfortable. For travelers, this is ideal weather: light sea breezes, low rain risk, and beaches that are lively but not overcrowded.

Tobago - Northeast & Main Ridge (Speyside, Charlotteville, Main Ridge Forest Reserve)

March sees the beginning of spring warmth and increased humidity; Main Ridge trails are comfortable in the morning but cloud and shower chances rise in the afternoons. Speyside’s famous dive sites start to show clearer conditions between showers, and cetacean sightings can be productive on calmer days. Travelers should prepare for variable conditions: sturdy hiking shoes, insect repellent and flexibility in dive bookings.
