Weather forecast for NRW: What does Dormouse Day bring?
The dormouse, this charming little rodent, is not only an attraction in the wildlife world, but also a key player in weather forecasting. Today, onJune 21, 2025, all eyes are on the weather on June 27th, the traditional Dormouse Day. According to information published by wa.de, the weather on this day will be decisive for the next seven weeks. Whether the forecast comes true or not remains to be seen, as the current weather situation is rather uncertain.
Weather expert Bernd Hussing from the German Weather Service warned that there are different forecasts for June 27th. The temperatures could be between21 and 29 degreesfluctuate, but whether we have to prepare for bright days or rainy weeks remains unclear. Hussing recommends not putting too much faith in the farmer's rule and instead checking the current weather report a few days before planned trips.
The dormice and his legend
Dormouse Day gets its name not only from the animal, but also from an ancient story. The name could also go back to the seven sleeping youths who sought protection in Ephesus during the persecution of Christians in 251 and woke up on June 27, 446. This legend is underpinned by belief in the resurrection, as rp-online.de explains. Many farming rules, which mainly come from the Middle Ages, draw their wisdom from often inaccurate climatic conditions.
One of the most famous farming rules says: “Whatever the weather is on June 27th, so will it be for the next seven weeks.” But here too, skepticism is warranted, as any weather expert would advise taking modern meteorology into account. So it may be better to believe the weather report more than the old wisdom.
