Czechia Climate – July 2026 Update
Top 5 Cities: Prague, Brno, Ostrava, Plzeň, and Liberec
Summary
Czechia experienced its 3rd warmest May to July on record, capping a period of intense heat and dry conditions across Central Europe that triggered severe wildfire warnings and health advisories. July itself delivered well-above-average warmth, keeping the country among the warmest regions globally relative to historic baselines. High temperatures and persistent sunshine continued to stress crops and water supplies, with elevated warmth projected to hold into late summer.
This month in numbers
The May to July period delivered an average temperature of 17.74°C, marking Czechia's 3rd warmest three-month start to summer on record since observations began in 1940 [May–Jul 2026]. That seasonal period sat 2.8°C above the 1961–1990 baseline, nearly touching the all-time period benchmark set in 2018 [May–Jul 2026]. For the single month of July 2026, the country recorded a mean temperature of 19.48°C, which was 2.5°C above the long-term baseline [Jul 2026]. This made it the 12th warmest July on record, driven by sustained tropical weather patterns across the region [Jul 2026].
What changed
The three-month thermal surge positioned Czechia 18th out of 232 tracked countries and territories globally for three-month temperature anomalies relative to historical baselines. This warmth ran ahead of the broader European average anomaly of 2.33°C (tracked at Europe) and aligned with planetary trends. Worldwide, global land temperatures recorded their 2nd warmest May to July period at 14.34°C, running 1.5°C above average, while single-month global temperatures ranked 3rd highest [Global May–Jul 2026, Global Jul 2026]. On a longer timeframe, Czechia continues its rapid warming trajectory, with a long-term trend running 1.86°C above the baseline following its hottest year on record in 2024.
What’s driving change?
The persistent warmth across Central Europe was primarily driven by recurring , where high-pressure systems trapped warm air masses over the continent. These atmospheric blockages were reinforced by that allowed weather patterns to stall, leading to reduced cloud cover, high evaporation rates, and drying soils. Furthermore, the broader European landmass exhibits how , causing inland regions to heat up more rapidly during continental warm spells than surrounding maritime areas.
Looking ahead
Extended seasonal forecasts indicate that above-average temperatures and drier-than-normal conditions are likely to persist across Central Europe through late summer and into early autumn.

Typical Climate – Czechia
Köppen Dfb · ContinentalCzechia has a continental climate (Köppen Dfb: Humid continental - warm summer), with distinct warm summers and cool-to-cold winters. July is typically the warmest month, averaging 19.1°C, while January is the coldest at -0.4°C. Annual precipitation averages around 667mm, spread fairly evenly across the year.

Shifting Seasons
Warm / cold seasonsKöppen Dfb · ContinentalHow spring and autumn have shifted in Czechia. Spring is defined as the date monthly temperatures first rise above the long-term annual mean (7.3°C, from 1940–1969); autumn is the date they fall back below it. Temperature swings 21.3°C peak-to-peak across the year - a classic four-seasons rhythm.

FAQs
FAQs
How is the climate in Czechia changing?
Czechia 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.
What is the climate like in Czechia?
Czechia has a continental climate (Köppen Dfb: Humid continental - warm summer), with distinct warm summers and cool-to-cold winters. July is typically the warmest month, averaging 19.1°C, while January is the coldest at -0.4°C. Annual precipitation averages around 667mm, spread fairly evenly across the year.
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?
The Czechia 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.
What counts as a Heatwave Day on the Czechia climate page?
Heatwave Days use the Warm Spell Duration Index (WSDI) - the WMO/ETCCDI-standard heatwave measure: days that are part of a run of 6 or more consecutive days above the local 90th-percentile temperature for that calendar day. The 90th-percentile threshold varies by time of year (a hot day in January is judged differently to one in July) but is fixed to the 1961-1990 baseline for every year shown - it does not shift as the climate warms, which is why Heatwave Days trend upward over time.
Does the Czechia climate page include frost and snow data?
Yes. Frost Days (days with a minimum temperature below 0°C, World Bank CCKP) and snow water-equivalent (GPCC) are shown alongside temperature and precipitation, each measured against the 1961-1990 baseline where a like-for-like historical comparison is available.
