Slovakia Climate
Top 5 Cities: Bratislava, Košice, Prešov, Žilina, and Nitra
This month in numbers
April 2026 in Slovakia was significantly warmer than average, ranking as the 6th warmest April in 86 years of records, with an average temperature of 10.59°C, an anomaly of +2.6°C compared to the 1961–1990 baseline. Globally, April 2026 was the 2nd warmest April on record for land temperatures, with an anomaly of +1.1°C. The three-month period from February to April 2026 also ranked as the 9th warmest on record for Slovakia, at 5.31°C, an anomaly of +2.4°C.
What changed
Slovakia has experienced a notably warm start to the year, with April's warmth following a March that was +3.6°C above average and a January that saw an even more striking +4.6°C anomaly. This consistently warmer trend for Slovakia contrasts with some other regions, as evidenced by 10 of the top 10 warmest 1-month anomalies globally being US states. Slovakia itself ranked 79th out of 234 regions for its April temperature anomaly. The country is also currently experiencing exceptional climatological and soil drought across its entire territory, with April marking the driest on record since 1881. This recent drought represents 100% of the drought events logged for Slovakia over the past 12 months, indicating an unusual concentration of dry conditions.
What’s driving change?
The persistent warmth and extreme dryness in Slovakia are influenced by several factors. The current ENSO state is Neutral, with a weekly Niño 3.4 SST anomaly of +0.9°C. However, a transition to El Niño conditions is likely by summer/autumn 2026, which typically brings warmer and drier winter conditions to the region, though its impact on summer temperatures is smaller. The () can also steer winter storms and affect temperature and precipitation patterns across Europe. The ongoing drought, which has seen precipitation totals drop below 50% of the long-term average in most areas, is causing underground water sources to dry up and raising concerns for agriculture and forestry.
Looking ahead
A transition to El Niño conditions is likely by fall 2026, with a 79% chance for June-August and an 87% chance for July-September, which could lead to warmer and drier than normal conditions for winter 2026-2027.

FAQs
FAQs
How is the climate in Slovakia changing?
Slovakia 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 trend rate is shown as °C per decade in the headline panel; you can also see the warmest and coolest years on file.
Where does the climate data for Slovakia come from?
Climate data for Slovakia 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 Slovakia climate update refreshed?
The Slovakia 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.
