Millions of residents in Germany’s cities are being exposed to moderate or extreme heat stress caused by high temperatures, dense surface sealing and too little greenery, according to the
second "heat check"
of NGO Environmental Action Germany (DUH). Over 12 million people in 190 cities with over 50,000 residents live in high-heat areas, DUH said based on a so-called heat stress index developed analysing satellite imagery.
Thirty-one cities received a "red card" when the NGO used the index to analyse the percentage of the population exposed to high-heat areas. Most cities (131) received a "yellow card", and 28 a "green card". In
its previous "heat check"
, 24 cities had received a "red card".
Cities in southern Germany scored especially badly, with between 88 and 91 percent of residents affected by extreme heat in Mannheim, Ludwigshafen and Worms, DUH said. "From now on, greening cities and preserving trees must be given the same priority as housing …

“Most intensive care units in Germany are now air-conditioned, but that's about as far as it goes.”
Officials warned that Germany is “insufficiently prepared” for extreme heat, just weeks before a blistering heatwave brought roads and transport to a standstill.

Yesterday (Sunday, 28 June)
Germany
broke temperature records for the third consecutive day, as a high-pressure pattern that traps hot air over Europe began shifting east.
The DWD German Weather Service provisionally measured temperatures reaching 41.7°C in a small rural settlement in Brandenburg. Tropical nights, where the temperature never drops below 20°C during a 24-hour period, also swept across the country – offering little relief from the intense heat.
Across Europe, more than 1,300
excess deaths
linked to the heatwave have been recorded since 21 June, according to the World Health Organisation (WHO).

This report is a key input to a
Summary Report by the World Bank
highlighting the urgent need for Germany to better prepare for climate related risks.
Heat stress is a growing concern across Europe, and Germany is no exception. Germany is
already experiencing intensifying heat waves
, with temperatures in early July 2025 reaching up to 40°C in several locations across the country. Due to the ‘heat island effect’ as well as a higher population density, urban areas are particularly affected. In addition, the increasing frequency of compound climate extremes creates multiple dimensions of risk. While some recent advances in policy can be recognised through the development of local heat action and adaptation plans, further action is needed to prepare for rising heat risks.
The aim of
this report
is, first, to i…

Climate change: Heat wave costs the German economy billions
Climate change: Heat wave costs the German economy billions
Never before has a June been as hot in Germany as in 2026. This has consequences not only for people and nature, but also for businesses. Heat reduces productivity and causes illness, while cooling is expensive.

Extreme heat could cost Germany up to $131 billion by 2030 and shave up to 3% off economic output if recent heat wave patterns persist, an
analysis from Allianz Trade showed
on Thursday.
Germany faces losses of up to $131 billion between 2026 and 2030 if heat waves seen in the past decade recur, the study showed
Rising temperatures cut productivity and push up energy costs, weighing on companies and investment, it added
Output losses of up to 3% of GDP are possible by 2030, placing Germany in the middle of Europe but on the losing side
Southern Europe remains the hardest hit, while hotter regions outside Europe have adapted more to extreme heat
Hamburg-based Allianz Trade said productivity drops by about 3% for each degree above 30°C, while energy costs rise roughly 1.2% per degree due to cooling needs
Heat also strains public finances, lowering tax revenues by about 0.7% annually and worsening Germany’s fiscal balance by around 0.9% of GDP per year, the analysis showed
Allianz Trade said adapting economies to extreme heat will become a key competitiveness factor.

Germany has experienced a series of extreme heat-related conditions, which have significantly impacted public health, agriculture, and the environment.
These conditions include record-breaking temperatures, prolonged droughts, wildfires, and flooding.
“Temperatures that can harm health have become more common in Germany. Six out of the
eleven
most extreme heat waves between 1951 and 2015 occurred after 2000. Since 1990, what were previously considered hot summers have become normal, with mean temperatures across Germany now well above the average of 30 years ago.”
Moreover, Germany experienced several intense heatwaves over the last decade as well, particularly notable in 2018, 2020, 2022, and 2023, as can be seen in the graph below of Temperature Anomalies in Germany for every year since 1881—having as a reference time temperatures from 1981 until 2010—with data provided by Germany’s national meteorological service (

Abstract
Heat is a global public health risk, even in temperate climates like Europe, which has experienced an increasing number of intense heatwaves over the past decade. This study uses a unique dataset of more than 57,000 X (formerly Twitter) conversations from users in Germany about heatwaves between 2013 and 2022. We showed that, as heatwaves in Germany have become more frequent and intense, social media activity on this topic has also increased. Structural topic modelling revealed nine topics, with an increase in the number and diversity of topics since 2018, a year marked by unprecedented drought and heat in Europe, including Germany. Before 2018, German he…

The
heat wave hitting parts of Europe
is stifling countries where people are not used to these temperatures and often live without air conditioning, such as Germany, which is better prepared for extreme cold than extreme heat. For that reason, German authorities have spent days warning of the danger of heatstroke and urging people
to drink plenty of water
, stay well cooled and be careful when out in the sun.
According to the German Weather Service (DWD), temperatures well above 30 degrees Celsius (86ºF) will be reached widely over the course of the week. In the western and southern regions of the country, temperatures will climb to 39ºC (102ºF) and, on Thursday, even 40ºC (104ºF) in some areas.
The high temperatures are leading many citizens to plunge into one of the countless lakes and rivers across the country. However, last week the German Life Saving Association (DLRG) urged people …

Heat - Heat Wave Fallout: Swiss Push for National Work Stop, Austria Enforces 491 Violations, Germany Faces €112 Billion Bill 20.06.2026 - Bild: über boerse-global.de
The push for a unified heat-protection standard at construction sites has gained new urgency in Switzerland, as the Aargau Building Contractors' Association demands clear, nationally binding rules for shutting down work during extreme temperatures. Switzerland currently lacks enforceable criteria, though a political proposal won approval from the National Council in late 2024; the Council of States has yet to vote. The union Unia goes further, calling for an automatic work interruption on all building sites once the mercury hits 33 degrees Celsius. Recent heat waves in June drove peaks of 37 degrees, triggering level-3 and level-4 warnings across large parts of the country.
Germany, meanwhile, faces a staggering economic toll. Allianz Trade calculations project that heat waves could cost the German economy roughly €112 billion by 2030. Allianz economist Katharina Utermöhl warns the country is insufficiently prepared. Sickness absence data show…
