Forecast for Trinidad and Tobago

Issued: 2026-04-04 17:05 AST

THIS EVENING, SATURDAY 4 APRIL: Widespread rain will continue across Trinidad and Tobago, with the heaviest downpours targeting the northeastern and eastern coastal districts. Temperatures will ease from the mid-to-upper 20s early evening into the mid-20s by late night. Rainfall totals will vary significantly, ranging from 3 mm in the northwest to up to 34 mm along the northeast coast. Moderate to heavy bursts will fall steadily through the evening and overnight. Easterly winds will blow at 10 to 30 km/h, with stronger gusts reaching 40 to 60 km/h. Given the combination of heavy rainfall, spring tides, and known drainage challenges, flash flooding is likely in low-lying urban zones and historically vulnerable valleys, while saturated slopes in northern Trinidad and across Tobago’s hills face an elevated landslide risk. Coastal waters will remain rough due to long-period swells and high tides.

TOMORROW, SUNDAY 5 APRIL: Overcast skies will dominate, with persistent light to moderate rain continuing across most districts. The overnight low will sit in the low-to-mid 20s, while the daytime high will climb from the upper 20s along the coast to around 31°C in the southern and western inland areas. Rainfall will be steadier than intense, with daily totals ranging from 1 mm in the west to up to 7 mm across the eastern and central regions. Showers will linger through the morning and afternoon before becoming more widespread again towards evening. Easterly winds will remain steady at 10 to 30 km/h, gusting up to 60 km/h. The ongoing moisture will keep soils saturated, maintaining a risk of localized flooding in poorly drained areas and continued landslide potential on steeper terrain in the north and Tobago.

▶ Impact-Based Forecast Context

Existing Vulnerabilities

Spring tides are in effect until Saturday, April 4, 2026, which can exacerbate coastal flooding and limit the drainage of inland floodwaters into the sea.
Northerly long-period swells are currently affecting marine conditions, increasing the risk of hazardous sea conditions for coastal communities and marine interests.
Many urban areas, particularly in the Greater Port of Spain region and valleys, have high susceptibility to flash flooding due to low topography, inadequate drainage infrastructure, and development on previously forested slopes.
Historically flood-prone communities, including Arouca, the Bamboo villages, Barrackpore, Debe, Diego Martin, Greenvale, Kelly Village, Madras, Mafeking, Manzanilla, Penal, St. Helena, and Woodland, remain highly vulnerable to rapid inundation during heavy rainfall.
Hillside communities in Tobago, such as Belle Garden, Les Coteaux, Moriah, Mason Hall, and Speyside, are particularly vulnerable to landslides and road damage during periods of persistent or intense rainfall.

Weather Impact Thresholds

Flash flooding: Can be triggered by intense, short-duration rainfall, especially in urban areas with poor drainage or in areas where watersheds have been denuded by construction.
Landslides: Risk increases significantly during and after heavy, multi-day rainfall events, particularly on saturated slopes in northern Trinidad and across Tobago.
Marine hazards: Marine interests are advised to exercise caution with waves in open waters reaching 1.5m to 2.5m and sheltered areas up to 1.0m, combined with the effects of spring tides.
Heat stress: With heat index values reaching 34°C, there is an increased risk of heat-related illness, particularly for vulnerable groups such as children and the elderly, if engaged in prolonged outdoor activity.

Exposed Populations and Assets

Coastal communities and infrastructure are exposed to potential inundation and erosion due to the combination of spring tides and long-period swells.
Residents in low-lying, flood-prone neighborhoods are at risk of property damage, loss of appliances, and disruption to essential services during heavy rainfall.
Transportation networks, including major roadways in northern Trinidad and coastal roads in Tobago, are vulnerable to closures caused by flooding or landslide debris.
Informal settlements located on steep, deforested slopes are at high risk of structural damage from landslides.

Upcoming Events

Good Friday (Public Holiday): April 3, 2026. This is a nationwide public holiday with church services and Holy Week observances, which may involve large gatherings and changes to normal traffic patterns.
Easter Monday (Public Holiday): April 6, 2026. This is a major public holiday traditionally associated with large crowds at beaches (e.g., Maracas, Las Cuevas, Mayaro) and increased traffic on coastal and eastern routes, significantly increasing exposure to coastal and weather-related hazards.
