This month in numbers
Trinidad and Tobago experienced its 13th warmest April on record, with an average temperature of 26.62°C, an anomaly of +0.8°C compared to the 1961–1990 baseline. The period of February–April 2026 ranked as the 7th warmest on record, with an anomaly of +0.9°C. Globally, April 2026 was the 2nd warmest April for land temperatures, with an anomaly of +1.1°C, while the February–April 2026 period also ranked as the 2nd warmest globally for land temperatures, with an anomaly of +1.2°C.
What changed
The past three months (February–April 2026) saw Trinidad and Tobago experiencing significantly warmer-than-average temperatures, ranking 7th warmest in 86 years of records. This trend aligns with the broader global picture, as global land temperatures for the same period also ranked as the 2nd warmest on record. Trinidad and Tobago's April anomaly of +0.80°C placed it 196th out of 234 regions in terms of warmth, indicating that while the region was warmer than average, other areas experienced more extreme heat.
What’s driving change?
The warmer temperatures in Trinidad and Tobago are occurring during a period of Neutral ENSO conditions, with the NOAA ONI 3-month anomaly for February–April 2026 at +0.11°C. However, forecasts indicate a strong likelihood of an El Niño developing in the coming months, with a 61% chance for May–July and an 87% chance for July–September. El Niño conditions are typically associated with drier conditions in the Caribbean and Atlantic basin. The Trinidad and Tobago Meteorological Service (TTMS) officially declared the start of the 2026 wet season on May 5th, triggered by the first tropical wave of the year. Despite this, the TTMS has indicated that May is a transition month, with rainfall episodes likely to be interspersed with dry spells and Saharan dust events. There were reports of heavy rainfall and localized flooding in parts of Trinidad in January 2026. The TTMS also noted a moderate chance for short-duration hot spells during the remainder of April and into May.
Looking ahead
The Trinidad and Tobago Meteorological Service forecasts above-normal mean temperatures for both islands from May to July 2026, with a moderate chance of short-duration hot spells, particularly in urban areas due to the effect.

Where does the climate data for Trinidad and Tobago come from?
Climate data for Trinidad and Tobago comes from Our World in Data, sourcing Copernicus ERA5 and HadCRUT5 (national temperature anomaly) and the Global Carbon Project via Our World in Data (CO₂ emissions), refreshed every month, when the upstream temperature and rainfall data are refreshed.
What is the climate baseline used on this page?
Anomalies on this page are calculated against the 1961-1990 climatological baseline, which is the standard reference period used by the Met Office, NOAA, IPCC and most national climate services. Some panels also show the source-native 1901-2000 (NOAA) or 1991-2020 (WMO) baselines for verification. See Methodology & Sources for the full reference.
