Top 5 Cities: Georgetown, Linden, New Amsterdam, Anna Regina, and Bartica
This month in numbers
Guyana experienced its 9th warmest June on record in 2026, with an average temperature of 25.15°C, marking an anomaly of +1°C compared to the 1961–1990 baseline. Globally, June 2026 was the 3rd warmest June for land temperatures on record, with an anomaly of +1°C. The three-month period from April to June 2026 also ranked as the 17th warmest on record for Guyana, with an average temperature of 25.27°C, an anomaly of +0.6°C.
What changed
The past three months (April–June 2026) in Guyana saw temperatures consistently above the historical average, with June's +1°C anomaly being particularly notable. This trend places Guyana's three-month anomaly at +0.64°C, ranking it 206th out of 234 regions globally. Within South America, Guyana recorded the warmest 1-month anomaly at +1.01°C, surpassing the group average of +0.60°C.
What’s driving change?
Guyana experienced significant rainfall and severe weather events throughout June 2026. Heavy rainfall and a storm breeze on June 15th led to critical flooding in Region Ten, forcing school closures and disrupting daily life in areas like Waterfront, Lamp Island, Jeep Landing, and Mackenzie Market Wharf. Additionally, a severe weather system around June 25th caused widespread damage to homes, public buildings, and electricity infrastructure in Region Two, with President Dr. Irfaan Ali leading inter-agency responses. Unstable atmospheric conditions, including tropical waves and fluctuations in the Inter-Tropical Convergence Zone, contributed to these intense rainfall events and thunderstorms across various regions. The Hydrometeorological Service also issued warnings about saturated soils and increased flood risk due to continuous rainfall.
Looking ahead
El Niño conditions are likely to develop within the next two to four months, with effects expected to become more pronounced from July onward and persist through the end of the year, potentially leading to a significantly drier and hotter second half of 2026 for Guyana.

Shifting Seasons
Wet / dry seasonsKöppen Af · TropicalGuyana doesn't have a warm/cold cycle - its monthly temperature range is only 1.8°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 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 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 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.
