Saturday was the hottest day of the year in NRW so far

It was already indicated by noon: the view of the thermometer showed 34 degrees Celsius. In the evening, the assumption was confirmed – Saturday was the hottest day of the year in North Rhine-Westphalia so far. And the hot weather continues.

The hot temperatures are not unusual for the time of year. “But it’s really special that the heat has lasted for seven or eight days,” says the weather expert. It is very exhausting for people.

According to the German Weather Service, the highest value in Germany was measured at the Trier-Petrisberg weather station (Rhineland-Palatinate) at 38.2 degrees. But that was not a new high for this year – it was on July 31st with 38.5 degrees in Rheinfelden in southern Baden. In Trier-Petrisberg, too, the maximum value that day was slightly higher at 38.4.

In the coming days, too, it should remain largely sunny and warm. In the mountains, however, there could be thunderstorms and local heavy rain on Sunday. According to the meteorologist, the Eifel and Rothaar Mountains are particularly affected. In the rest of the state it remains hot with temperatures above 30 degrees. Even in the nights there should be hardly any cooling because the heat builds up. “The problem is that you can hardly ventilate at night because it stays so warm,” said the weather expert. Instead, she advises ventilating early in the morning.

Despite the maximum temperature for 2020, the previous year’s record has not yet been reached. In 2019, peak temperatures over 41 degrees were reached in some places in North Rhine-Westphalia.

The hot, sunny weather has also increased the ozone concentration in the air we breathe. In Krefeld, a maximum value of 219 micrograms per cubic meter of air was measured on Saturday, as the State Office for Nature, Environment and Consumer Protection (LANUV) announced.

Ozone is a colorless and poisonous gas in the atmosphere. It can irritate the mucous membranes and cause respiratory problems and headaches. A natural ozone layer at a height of over 20 kilometers protects the earth from harmful UV radiation. Near the ground, when there is strong solar radiation, it is formed by chemical processes from pollutants such as nitrogen oxides. If the concentration exceeds 180 micrograms per cubic meter, the public must be informed. The warnings apply to all people from 240 micrograms.
