Vietnam Climate – June 2026 Update
Top 5 Cities: Hanoi, Ho Chi Minh City, Hai Phong, Da Nang, and Can Tho
This month in numbers
Vietnam experienced a warmer-than-average June 2026, with temperatures reaching 26.86°C, an anomaly of +0.7°C compared to the 1961–1990 baseline. This ranked as the 26th 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.
What changed
The April–June 2026 period saw an average temperature of 26.21°C, marking it as the 24th warmest such period on record, with an anomaly of +0.6°C. Vietnam's 1-month anomaly for June was +0.67°C, placing it 170th out of 234 regions globally. The country's 3-month anomaly of +0.61°C ranked it 207th globally. The long-term trend for Vietnam shows a significant warming of +1.16°C compared to the 1961–1990 baseline, with 2025 being the warmest year on record.
What’s driving change?
The current climate patterns in Vietnam are significantly influenced by a weak El Niño, with a +0.98°C anomaly in the NOAA ONI 3-month (April-June 2026) index. This El Niño is expected to strengthen and persist through early 2027, with a high probability of becoming a strong to very strong event. El Niño typically brings warmer and drier conditions to Maritime Southeast Asia, including Vietnam, increasing the risk of heatwaves and drought. Indeed, Vietnam experienced a prolonged heatwave in late May and early June, particularly in northern and central regions, with temperatures exceeding 40°C in some areas. However, an unusual late-season cold air mass brought heavy rainfall and cooler temperatures to northern Vietnam in early June, providing temporary relief from the heat and highlighting the increasingly unpredictable nature of weather events. Despite overall forecasts for reduced rainfall, localised extreme rainfall events remain possible.
Looking ahead
El Niño conditions are forecast to continue strengthening through the end of 2026 and into early 2027, suggesting a continued likelihood of above-average temperatures and potential for more frequent and intense heatwaves, as well as risks of drought and water shortages, particularly in central and southern Vietnam.

FAQs
FAQs
How is the climate in Vietnam changing?
Vietnam 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 Vietnam come from?
Climate data for Vietnam 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 Vietnam climate data cover?
The Vietnam climate profile covers Hanoi, Ho Chi Minh City, Hai Phong, Da Nang and surrounding areas. Temperature, rainfall and emissions data for Vietnam
How often is the Vietnam climate update refreshed?
The Vietnam 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.
