Czech meteorologists are warning that an exceptionally strong El Niño, described in global reporting as potentially the strongest on record, will shape the country's winter weather. Measured conditions already lean that way: rainfall for 9 July–6 October 2026 came in about 32% below the 1991–2020 normal, and mean temperatures ran roughly 2.3°C above normal, even though that window is climatologically Czechia's dry season. The practical concern is therefore not the 2026 harvest, which finished on schedule, but whether the autumn and winter recharge rains arrive in time to refill soils and reservoirs.
138.3 mm vs 203.8 mm normal
Reanalysis shows rainfall for 9 July–6 October 2026 running about 32% below the 1991–2020 normal, though this window is climatologically Czechia's dry season, so the meaningful question is whether the autumn recharge rains arrive on time.
News source19.48°C mean vs 17.21°C normal
Mean temperature over the same window ran about 2.3°C above normal, consistent with the record-strength El Niño signal meteorologists describe for winter 2026/27.
News sourceSpring planting (Mar–May), the May–September growing season and the August–October harvest all proceeded on schedule, with the warm, dry signal mainly a concern for soil moisture recharge and winter wheat establishment rather than for the 2026 harvest itself.

Sector by sector
The 2026 harvest and growing season passed on schedule, but a warm, dry winter would leave soils short of moisture for spring planting and could stress winter cereals and oilseed rape.
With the July–October window already about 32% short of normal rainfall, reservoir and groundwater recharge depends on whether the coming autumn and winter precipitation arrives on time.
A milder, drier winter is expected to ease cold-related mortality but may extend the pollen and vector season and sustain heat-stress risk in summer.
Meteorologists quoted in the coverage play down a dramatic El Niño effect on Nordic and Central European power, though a milder winter would typically trim heating demand while low river levels can constrain hydro and cooling water.
Warmer winters and lower river flows can reduce oxygen levels in Czech ponds and streams, a particular risk for the country's extensive carp aquaculture.

2023-24
Strong El Niño conditions accompanied a record-warm global year and an unusually warm Czech winter, with above-normal temperatures and variable precipitation.
unsourced background2015-16
A very strong El Niño coincided with an exceptionally mild, dry Czech winter, contributing to early-season soil moisture deficits that persisted into spring.
unsourced background1997-98
One of the strongest El Niño events of the century, associated with a mild, precipitation-poor winter in Central Europe and below-average snowpack in Czechia's border mountains.
