Poland Climate – June 2026 Update
Top 5 Cities: Warsaw, Kraków, Łódź, Wrocław, and Poznań
This month in numbers
Poland experienced a significantly warmer June, with an average temperature of 17.75°C, an anomaly of +1.6°C compared to the 1961–1990 baseline. This ranked as the 19th 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 period of April–June 2026 saw an average temperature of 13.2°C, marking an anomaly of +1.1°C and ranking as the 18th warmest such period on record. This trend aligns with the broader European picture, as the average temperature over European land in June 2026 was the second-highest on record for the month. Poland's 1-month anomaly was 0.94°C cooler than the European group average.
What’s driving change?
Poland experienced an extreme heatwave towards the end of June, with temperatures reaching a record-breaking 40.5°C in Słubice on June 28, surpassing the previous all-time high of 40.2°C. This heatwave was part of a larger pattern across Europe, with many countries breaking temperature records. The extreme heat led to a tragic spike in drownings, with at least 70 people losing their lives in Polish waters since the beginning of June as they sought to cool off. Following the heat, severe thunderstorms, heavy rainfall, and strong winds swept across much of the country. This extreme weather is consistent with seasonal shifts and the broader trend of a warming climate, which is making such events more frequent and intense.
Looking ahead
Forecasters have indicated that while extremely high temperatures were expected to continue into early July, the weather would begin to cool thereafter.

FAQs
FAQs
How is the climate in Poland changing?
Poland 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 Poland come from?
Climate data for Poland 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 Poland climate update refreshed?
The Poland 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.
