The weather in the heart of Berlin is strongly influenced by the urban heat island effect. The dense construction at Alexanderplatz and around Potsdamer Platz stores solar energy, leading to higher temperatures than in the outer districts. An hourly forecast is essential for planning a day between Museum Island, Tiergarten, and shopping on Friedrichstraße.
In spring, the city center warms up quickly. The hourly forecast helps find the perfect time for a photo at the Brandenburg Gate in the best light. In summer, the heat in the street canyons can be intense. The cooling effect of the Spree River and the vast green space of the Tiergarten then become important refuges. The hourly forecast for thunderstorms is crucial to avoid getting wet at an open-air event.
In autumn, the wind can whistle through wide avenues like Straße des 17. Juni, lowering the feels-like temperature. The hourly wind forecast is useful here. In winter, temperatures are often one or two degrees milder than on the outskirts, but the tall buildings can create frosty shadow areas. An hourly forecast helps to assess the risk of icy sidewalks and squares while visiting the many Christmas markets, such as the one at Gendarmenmarkt.
