Top 5 Cities: Belize City, San Ignacio, Belmopan, Orange Walk, and Dangriga
This month in numbers
Belize experienced its 17th warmest June on record, with an average temperature of 27.36°C, marking an anomaly of +0.9°C compared to the 1961–1990 baseline. The period of April–June 2026 was the 13th warmest on record for Belize, with an average temperature of 27.34°C, an anomaly of +1.1°C. Globally, June 2026 ranked as the 3rd warmest June for land temperatures, with an anomaly of +1°C, while the April–June 2026 period was the 2nd warmest on record for global land temperatures, also with an anomaly of +1°C.
What changed
Belize's recent temperatures continue a long-term warming trend, with the latest full-year average temperature in 2025 reaching 26.66°C, making it the warmest year on record. This contributes to a long-term trend of +1.51°C compared to the 1961–1990 baseline. The country's June anomaly of +0.9°C places it 151st out of 234 regions in terms of one-month temperature anomalies.
What’s driving change?
The developing El Niño conditions are a significant driver of the current climate patterns in Belize. The World Meteorological Organization (WMO) estimated an 80% likelihood of El Niño during June to August 2026, with a more than 90% chance of it persisting through November. El Niño typically raises global temperatures and alters rainfall patterns. Belize experienced heavy rainfall between June 10th and 11th, which was attributed to excess moisture from the Pacific Ocean associated with the remnants of Tropical Storm Cristina and the passage of a tropical wave. This led to impassable roads in some areas, particularly in the southern Stann Creek District.
Looking ahead
The seasonal outlook for June–July–August 2026 suggests that rainfall will be below normal to normal over most of Belize, while both daytime and night-time temperatures are expected to be warmer than usual.

Shifting Seasons
Wet / dry seasonsKöppen Am · TropicalBelize doesn't have a warm/cold cycle - its monthly temperature range is only 4.3°C across the year - but it does have a strong wet/dry cycle (the wettest month gets 5× as much rain as the driest). So we track how the wet season has shifted instead.

FAQs
FAQs
How is the climate in Belize changing?
Belize 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 headline panel also shows the long-term trend rate per decade and the warmest and coolest years on file.
Where does the climate data for Belize come from?
Climate data for Belize 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 Belize climate update refreshed?
The Belize 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.
