The people in Berlin and Brandenburg have to be prepared for hot days. On Tuesday, the temperatures will rise to highs of between 31 and 37 degrees, as the German Weather Service (DWD) announced on Tuesday morning. With a lot of sunshine, the day can also be physically demanding. During the night it usually stays warm with lows between 15 and 21 degrees.

According to the DWD, the preliminary peak of the heat wave will be reached on Wednesday, when the 40-degree mark can also be cracked. With temperatures between 34 and 40 degrees and lots of sunshine, places in the outdoor pool or at the bathing lake should be in demand.

According to the forecast, it can also rain or thunderstorm in places during the night. With lows between 18 and 23 degrees at night, there is no sign of cooling down.

According to the DWD, the weather will be changeable and cloudy on Thursday. Accordingly, showers and sometimes thunderstorms are to be expected, especially in the north. According to the forecast, areas in the south may remain dry. With highs between 26 and 31 degrees, it will be a little less hot.

Because of the high temperatures and persistent drought, the highest forest fire hazard level 5 was proclaimed for almost all Brandenburg districts on Tuesday. According to the state environment ministry, level 4 only applied in the district of Oberhavel. In the forest fire control center there are always new alarms for smaller fires, the state’s forest fire protection officer, Raimund Engel, reported to the German Press Agency. He assumed that the highest level of forest fire danger would be declared nationwide on Wednesday.

Because of the “very high risk of fire”, everything that could lead to a fire in the forest and in the fields should be avoided, according to an official hazard notification. “The smallest spark can trigger a disaster. Human activity causes more than 90 percent of all forest fires.”

In particular, no smoking and no fire should be lit, not even in the vicinity of forests, it said. Nor should smoldering cigarettes be thrown out of the car. Fires should be reported immediately to the fire department or police. Of course, all of this also applies elsewhere, where the highest level of forest fire danger does not apply.

The Berlin Senate Department for Health provides tips for correct behavior at high temperatures on its website. She recommends, among other things, the continuous drinking of non-alcoholic beverages and the enjoyment of light food such as fruit and vegetables rich in water.

Physical stress such as sport should also be avoided. “If you have to do physical work, pay attention to your fluid intake and drink enough,” advises the health administration. Outdoor activities should be shifted to the morning and evening hours. Direct sunlight should be avoided; the authority advises sunscreen, air-permeable clothing, hats and sunglasses.

Rooms should be ventilated as early as possible in the morning, in the evening or at night when the air outside is cooler than inside. “Darken the rooms with shutters, awnings and curtains during the day,” the health administration website also says.
