Heat shock in Freiburg: How to protect yourself from the strong sun!
On June 13, 2025, the residents of Freiburg im Breisgau can expect a really hot day. The Center for Medical-Meteorological Research is currently issuing a weather warning due to intense heat. This refers to the period from today, 11:00 a.m., to tomorrow, 7:00 p.m. The temperatures should fluctuate between 22 and 29 °C, so a cool place in the shady areas can be of good use.
It looks like the weather in Freiburg will be mostly clear with light to no wind. At night the temperature remains moderate and lies between 14°C and 24°C. This morning, the people of Freiburg were already expecting 21 °C, before temperatures rose to 28 °C in the afternoon. In the evening it cools down to a pleasant 24 °C.
Check your UV protection!
What is particularly alarming is the high UV index of 8.468, which means very strong UV exposure. Such high values do not occur often in Freiburg and require appropriate protective measures. According to the Weather Service, you should aim for a sun protection factor (SPF) of at least 30, especially if you have fair skin. Practical tips include wearing protective clothing, sunglasses and avoiding the bright midday sun between 10am and 4pm. You should also make sure to drink enough and apply cream regularly, even after swimming.
A hot day is also forecast for tomorrow, June 14th. Temperatures range from a morning high of 22°C to peaks of 29°C during the day. A light rain front could cool things down in the evening. If you keep a close eye on the forecast for the coming week, you will also find out that it will remain relatively hot at 28 °C on Friday, before rain could cool things down on Saturday and Sunday. The other highs are 29 °C on Saturday and 23 °C on Sunday.
Health dangers from heat
However, the persistent heat not only poses a challenge for leisure activities, but can also pose health risks. Heat warnings, which are issued by the German Weather Service, among others, also take night-time exposure into account. These warnings are important, especially for sensitive people. Even without explicit warning, people can suffer from the heat, so everyone should listen to their body and retreat if necessary.
Finally, it remains to be said that the people of Freiburg can prepare for an exciting but also strenuous weather period. Depending on the season and the upcoming temperatures, all preparations for sun protection and your own health should be made. Anyone who can prepare well in the heat will be able to enjoy the summer days in Freiburg.
