Czechia Climate – June 2026 Update

Top 5 Cities: Prague, Brno, Ostrava, Plzeň, and Liberec

This month in numbers

Czechia experienced its 6th warmest June on record, with an average temperature of 18.33°C, a significant 2.9°C above the 1961–1990 baseline. The period of April to June 2026 also ranked as the 8th warmest on record, with an anomaly of +1.8°C. Globally, June 2026 was the 3rd warmest June for land temperatures, while the April–June period ranked as the 2nd warmest on record for global land temperatures.

What changed

This past June saw Czechia significantly warmer than its historical average, continuing a trend of elevated temperatures. The country's June anomaly of +2.9°C was notably higher than the overall European group average of +2.56°C for the same month, placing Czechia 39th out of 234 regions globally for its 1-month anomaly. The previous year, 2025, was the warmest on record for Czechia, with an average temperature of 10.55°C.

What’s driving change?

June 2026 was marked by an unprecedented and severe heatwave across Central Europe, including Czechia. On June 29, Czechia recorded an all-time high temperature of 41.9°C in Doksany, breaking the previous record by an "unprecedented" 1.5°C. This extreme heat was driven by a powerful heat dome that trapped hot air over the region, leading to dangerously high daytime temperatures and tropical nights that prevented overnight cooling. The heatwave also led to a smog alert in Prague due to high concentrations of ground-level ozone. Towards the end of June, severe thunderstorms, large hail, heavy rain, and destructive winds swept across several regions of Czechia, causing damage to gardens and infrastructure. More information on extreme weather events can be found at Extreme Weather tracker.

Looking ahead

The ongoing heatwave across Europe suggests that warmer-than-average conditions are likely to persist in the coming weeks and potentially months.

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 Czechia come from?

Climate data for Czechia 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 Czechia climate data cover?

The Czechia climate profile covers Prague, Brno, Ostrava, Plzeň and surrounding areas. Temperature, rainfall and emissions data for Czechia

How often is the Czechia climate update refreshed?
