Hungary's 2026 drought is the country's most severe in 126 years, data shows

What is a drought, and what does it mean to say that Hungary's 2026 drought was the most severe in 126 years?

A drought is a prolonged period when rainfall is far below normal, causing water shortages in soil, rivers, groundwater, and other supplies. It matters because dry conditions can damage crops, lower river levels, and weaken the water cycle. Hungary’s 2026 event was not just a brief dry spell.

HungaroMet ranked it as the country’s most severe drought in 126 years. The drought followed unusually low winter rainfall, very dry spring conditions, and heatwaves in June, July, and August. By late June, almost the entire country had a soil moisture deficit exceeding 100 millimetres in the top metre.

The record reflects both duration and intensity across the country. From 1 April to 2 September, at least 30% of Hungary experienced moderate or worse drought for nearly 84% of the period. By late August, severe agricultural drought covered half the country, while groundwater levels remained well below ideal.

How extreme were Hungary's weather conditions in 2026 compared with normal levels for rainfall and temperature?

Hungary’s 2026 weather was extreme because both rainfall and temperature moved far from normal at the same time. Low rainfall reduced available water, while unusual heat increased evaporation. Together, these pressures dried soils faster than ordinary seasonal conditions would.

Average summer rainfall was just 74.1 millimetres. That was 36% of the 1991–2020 mean. The country’s seasonal mean temperature reached 23.43°C, compared with a long-term norm of 20.84°C. The difference was 2.59°C, making the summer the second hottest on record.

HungaroMet also identified the summer as Hungary’s driest since 1901. The heat and lack of rain affected the wider water system, not only fields. Water levels in the Danube fell to record lows, and soil moisture declined sharply. These figures show why the drought became a national water shortage rather than an isolated dry period.

What sequence of dry and hot weather caused the drought to persist from late 2025 through the summer of 2026?

The drought developed through a sequence of weather stresses rather than one isolated event. A winter with lower-than-usual rainfall left Hungary with less water entering the soil and wider water system. The shortage then continued into spring, when temperatures and rainfall patterns failed to restore moisture.

January was cold and wet, but the following months brought severe rainfall shortages and above-normal temperatures. April was especially dry, receiving only 10% of its usual rainfall. May included wetter periods, yet soil moisture had not recovered by the end of spring. Heatwaves arrived in June, followed by further hot spells in July and August.

This sequence allowed the deficit to persist. Dry weather reduced replenishment, while heat increased evaporation from soil and water surfaces. By late June, almost the entire country had more than a 100-millimetre soil moisture deficit in the top metre. Summer then deepened the existing shortage instead of reversing it.

How do high temperatures and low rainfall reduce soil moisture and disrupt the water cycle?

Soil moisture depends on a balance between water arriving and water leaving. Rain replenishes soil, rivers, and groundwater. Heat increases evaporation from the ground and plants, so more water moves into the atmosphere. When rainfall stays low, that lost water is not replaced quickly enough.

HungaroMet reported that Hungary’s lack of rainfall, combined with temperatures far above average, increased evaporation losses. By late June, almost the entire country had a soil moisture deficit greater than 100 millimetres in the top metre of soil. April rainfall was only 10% of usual, and summer brought more dry spells.

This disrupts the water cycle by reducing water stored in the ground and increasing atmospheric losses from evaporation. Soil then holds less moisture for crops and ecosystems. The effects can persist because later rain first has to refill the depleted soil and groundwater. The article reports that soil moisture was already far below normal in 2025 and worsened in 2026.

What are agricultural drought and groundwater shortages, and why can they continue even after wetter weather arrives?

Agricultural drought occurs when dry soil and limited water make conditions increasingly difficult for farming. Groundwater shortages occur when underground water levels fall below healthy or ideal levels. They matter because a rainy day or short wet period may not restore the deeper stores that fields and water systems depend on.

In Hungary, agricultural drought had reached severe levels across half the country by the end of August. Groundwater was estimated to be 1.4 to 1.7 metres below what is considered ideal. Soil moisture was already far below normal in 2025, then deteriorated further during 2026’s dry and hot conditions.

Wetter autumn weather alone would not solve the shortage. Rain must first replenish severely depleted soil before more water can move underground. The article says Hungary needs to retain water rather than let it drain away quickly. Farming changes, structural reforms, and major investment would be needed to improve recovery and resilience.

What consequences can Hungary's drought have for farming, the Danube, ecosystems, and water supplies?

Hungary’s drought affects more than crops. Farms face severe agricultural drought when soils lack the moisture needed for production. Rivers and underground reserves also shrink, reducing water available to natural systems and communities. The article links the wider crisis to falling groundwater and record-low Danube levels.

By late June, almost the entire country had a soil moisture deficit exceeding 100 millimetres in the top metre. By late August, severe agricultural drought covered half the country. Unusually dry conditions also produced record-low water levels on the Danube. Groundwater levels were estimated at 1.4 to 1.7 metres below ideal, showing that the shortage reached below the surface.

These conditions can strain farming, ecosystems, rivers, and water supplies at the same time. The article does not quantify crop losses or specific ecological damage, but it shows broad water-system stress. Even wetter autumn weather would not be enough alone. Hungary needs better water retention, farming changes, structural reforms, and investment.

Why would retaining rainwater and river water, rather than allowing it to drain away quickly, help Hungary manage future water shortages?

Water retention means keeping more rainwater and river water in the landscape instead of allowing it to drain away quickly. This matters because stored water can help refill dry soils and support groundwater after rainfall stops. It can also reduce the gap between wet periods and later drought.

Hungary’s experts have warned for years that the country must retain water to tackle its crisis. The need is clear after the 2026 drought: soil moisture was severely depleted, the Danube reached record-low levels, and groundwater was estimated 1.4 to 1.7 metres below ideal. Fast drainage would not rebuild these reserves.

Retention would not remove the need for rain, but it could make rainfall more useful and improve recovery after dry spells. The article says this approach requires changes in farming practices, major structural reforms, and investment. Without those changes, even wetter autumn days would not be enough to solve the shortage.
