Cambodia Climate – June 2026 Update
This month in numbers
Cambodia experienced a June that was 0.5°C warmer than the 1961–1990 baseline, ranking as the 33rd warmest June in 86 years of records. Globally, June 2026 was the 3rd warmest June on record for land temperatures, with an anomaly of +1°C compared to the 1961–1990 baseline.
What changed
The April–June 2026 period saw Cambodia's average temperature at 28.45°C, an anomaly of +0.6°C, making it the 25th warmest such period on record. This trend aligns with the broader global picture, as global land temperatures for the same three-month period ranked as the 2nd warmest on record, with an anomaly of +1°C. Cambodia's 1-month anomaly places it 185th out of 234 regions, while its 3-month anomaly is 210th out of 234, indicating that while the country is experiencing warmer conditions, other regions are seeing more significant temperature increases.
What’s driving change?
The warming trend in Cambodia is influenced by the developing El Niño phenomenon. The World Meteorological Organisation forecasts an 80% likelihood of El Niño during June to August 2026, with the probability rising to over 90% by November. This El Niño event is expected to bring typically drier weather to much of the Maritime Continent and southern Mainland Southeast Asia, including Cambodia. The Ministry of Water Resources and Meteorology issued a public announcement in June alerting to the potential impact of El Niño, with a forecast of increased heat and drought conditions. Cambodia also experienced Tropical Storm Jangmi from May 28 to June 2, 2026, which brought heavy rain, strong winds, and thunderstorms across the country.

Shifting Seasons
Wet / dry seasonsKöppen Aw · TropicalCambodia doesn't have a warm/cold cycle - its monthly temperature range is only 3.6°C across the year - but it does have a strong wet/dry cycle (the wettest month gets 30× as much rain as the driest). So we track how the wet season has shifted instead.

FAQs
FAQs
How is the climate in Cambodia changing?
Cambodia 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 Cambodia come from?
Climate data for Cambodia 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 Cambodia climate data cover?
Temperature, rainfall and emissions data for Cambodia Cambodia climate profile with temperature anomalies, rainfall (CRU TS), warm/wet-season shift analysis, CO₂ emissions (Our World in Data) and electricity generation mix — all vs the 1961–1990 baseline..
How often is the Cambodia climate update refreshed?
The Cambodia 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.
