This month in numbers
Guyana experienced an April 2026 average temperature of 25.42°C, an anomaly of +0.3°C compared to the 1961–1990 baseline. This ranked 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, ranking as the 24th warmest such period on record. This places Guyana as the 4th coolest in the cross-region rankings for this three-month anomaly, sitting at 231st out of 234 regions. 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 latest annual average temperature in 2025 was 26.51°C, making it the warmest year on record.
What’s driving change?
Guyana experienced significant rainfall and widespread flooding in March and April 2026. Unstable atmospheric conditions, including strong low-level convergence and moisture transport from trade winds, led to frequent showers, moderate to heavy rainfall, and isolated thunderstorms. This resulted in localised flooding, particularly in low-lying and poorly drained areas, and also contributed to hazardous driving conditions. The Inter-Tropical Convergence Zone (ITCZ) also played a role, with its gradual strengthening and oscillation contributing to the unsettled conditions. Additionally, a major Saharan Dust surge affected Guyana in February 2026, leading to reduced visibility and unhealthy air quality levels.
Looking ahead
El Niño conditions are likely to develop within the next two to four months, which could lead to a significantly drier and hotter second half of 2026 for Guyana.

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.

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.
