Allgäu in the heat record: temperatures over 32 degrees on the hottest day!

What a hot day! July 2, 2025 will go down in history as the hottest day of the year in Germany, with record-breaking temperatures of up to 39 degrees Celsius Allgäu newspaper reported. People were particularly challenged in the Allgäu, because here too the temperatures rose to over 30 degrees. The highest temperatures of 2025 were even recorded in Leutkirch, Memmingen and Kaufbeuren.

The reports from the weather services are alarming: 30.1 degrees were measured in Oberstdorf, 32.1 degrees in Kempten and 32.4 degrees in Sigmarszell. This is just a small part of the heat that Germany is currently experiencing. Experts predict that we are dealing with a massive heatwave that could potentially even exceed 40 degrees. In fact, it shows engineer, that Germany is experiencing the driest first half of the year since 1893 and the forecasts for the coming days promise little relief.

The health risks are increasing

So what does this mean for our health? In many regions of Europe there are health risks caused by the extreme heat. In cities like Athens, temperatures have even risen to 45 degrees, which has already led to deaths, such as ZDF reported. Older people and the chronically ill, among others, are particularly at risk here. At temperatures like this, even climbing to the Acropolis becomes a risk, as tourists are banned from 43 degrees in the shade.

The urbanization of cities is also particularly dangerous: the heat is increased by concrete and asphalt, which leads to a further accumulation of hot days. The German Weather Service defines a heat wave in Germany as at least three consecutive days above 30 degrees, which we can enjoy in the coming days. To counteract the health risks, there are a few simple recommendations: drink plenty of water, avoid direct sunlight and, above all, keep an eye on people at risk.

The causes of the heat wave

How does this extreme weather situation come about? Heat waves are caused by stable high pressure levels that block cool air masses. A high pressure area is expected over western Europe this week, bringing in hot air from North Africa. This not only leads to enormous temperatures, but also to a dramatic increase in water temperatures in the Mediterranean, which are above the long-term average. A term that is often used in this context is the “heat dome,” which describes blocking high pressure areas that trap heat like in a pot.

A look at historical heat waves shows that the intensity and frequency of such events are being increased by climate change. More than two-thirds of the most severe European heat waves since 1950 went unnoticed before 2000. Experts warn that by 2050, half of Europe's population could suffer from high levels of heat stress in summer.

With that in mind, stay cool and make sure you take care of yourself and others in this relentless heat!
