Budapest warming climate could redefine “extremes” in just a few decades

Budapest’s climate is set to undergo significant transformation in the coming decades, with hotter temperatures, drier summers and more intense weather extremes becoming the norm.

Budapest may witness a significant warming in the future

According to climate expert Márk Honti, speaking at a recent Earth Day conference in the capital, the Hungarian city could eventually experience conditions similar to parts of northern Iran if current global emission trends continue.

According to Telex’s report, winters will not disappear entirely, but the overall trajectory is clear: rising temperatures across most seasons and increasingly erratic weather patterns. In fact, the changes may feel as though Budapest is gradually shifting south-eastwards on the map rather than simply warming.

Climate models point to inevitable warming

Despite uncertainties in forecasting, one conclusion is consistent across all climate models: Budapest will warm. The extent of that warming, however, depends heavily on global efforts to reduce greenhouse gas emissions.

Under a more optimistic scenario, where emissions are curbed in the near future, most warming would occur by around 2050, followed by a slower increase. In contrast, a pessimistic outlook suggests that temperatures will continue rising steadily until the end of the century, leading to far more dramatic consequences.

Climate modelling has improved significantly over the past three decades, combining global and regional simulations. While global models capture large-scale trends, higher-resolution regional models allow scientists to better understand local impacts, including how Hungary’s terrain influences weather patterns.

Heatwaves intensify, rainfall becomes erratic

One of the most noticeable changes will be the sharp rise in extremely hot days. By mid-century, the number of days exceeding 35°C could increase by 85–110%, and potentially double or more by 2100 under worst-case scenarios. Heat alerts, once considered exceptional, may become routine.

At the same time, cold extremes will decline but not vanish. Frosty winter days will still occur, meaning Budapest will not turn into a subtropical city, despite the warming trend.

Rainfall patterns are also expected to shift. While total annual precipitation may not change dramatically, its distribution will. Fewer rainy days are likely, but when rain does fall, it will arrive in intense bursts, often following prolonged dry spells. This creates challenges for agriculture, water management and urban infrastructure.

Redefining the word “extreme”

As extreme weather events become more frequent, experts warn that society may need to rethink what qualifies as “extreme”. Events that once occurred every few decades could become commonplace.

The implications extend beyond temperature and rainfall. Changes across the Danube’s wider catchment area could lead to both higher average water levels and greater fluctuations, increasing the risk of both floods and droughts.

Adaptation is now unavoidable

While reducing emissions remains critical, experts say adaptation is equally urgent. Cities like Budapest must rethink infrastructure, water management and urban planning to cope with the unavoidable impacts of climate change. As Honti emphasised, the future will depend not only on global action but also on how effectively societies prepare for a rapidly changing environment.
