This month in numbers
Guyana experienced an average temperature of 25.42°C in April 2026, marking an anomaly of +0.3°C compared to the 1961–1990 baseline. This ranks as the 26th warmest April in 86 years of records. Globally, April 2026 was the 2nd warmest April on record for land temperatures, with an anomaly of +1.1°C.
What changed
The three-month period from February to April 2026 saw an average temperature of 25.18°C, an anomaly of +0.4°C above the 1961–1990 baseline, ranking as the 24th warmest such period on record. This places Guyana at 228th out of 234 regions globally for its 3-month anomaly, indicating it was among the cooler regions compared to the global average. In contrast, the global land temperature for the same three-month period was the 2nd warmest on record, with an anomaly of +1.2°C. Guyana's annual average temperature for 2025 was 26.51°C, making it the warmest year on record.
What’s driving change?
Guyana is currently in an ENSO-neutral phase, with a Niño 3.4 SST anomaly of +0.11°C for February-April 2026. However, forecasts indicate a strong likelihood of an El Niño developing by May-July 2026, with probabilities rising to 79% by June-August and 87% by July-September. /climate/enso. This shift to El Niño typically brings warmer and drier conditions to the region. In April 2026, Guyana experienced widespread rainfall and potential flooding, particularly from April 22nd to 25th, with some areas receiving over 100mm of rain in 24 hours. The Hydrometeorological Service advised that unstable atmospheric conditions, associated with a surface trough and a strengthening Inter-Tropical Convergence Zone (ITCZ), contributed to increased cloudiness, frequent showers, and thunderstorms. This follows earlier warnings of prolonged rainfall and flooding from April 1st to 3rd.

Data Sources for Guyana
Every figure on this page is sourced from official, openly published climate datasets. Anomalies are calculated against the 1961–1990 baseline (temperature) and 1991–2020 (rainfall, sunshine, frost) — see the Methodology & Sources page for the complete dataset list and update calendar.
FAQs
FAQs
How is the climate in Guyana changing?
Guyana is warming in line with the rest of the world. The page above shows the latest monthly temperature anomaly versus the 1961-1990 baseline, the long-term annual trend, and the region's rank in the historical record. The trend rate is shown as °C per decade in the headline panel; you can also see the warmest and coolest years on file.
Where does the climate data for Guyana come from?
Climate data for Guyana 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.
Which areas does the Guyana climate data cover?

How often is the Guyana climate update refreshed?
The Guyana climate update is refreshed monthly, typically a few days after the previous month closes and the upstream provider (Met Office HadUK-Grid, NOAA Climate at a Glance, Copernicus ERA5 or the Global Carbon Project) publishes its update. See the Climate Rankings for cross-region comparisons.
