12/28/2022 0 Comments April weather in vienna![]() ![]() In Waidhofen an der Ybbs (Lower Austria), a new Austrian record was set on April 28 with 32 degrees. Air from the Sahara drove temperatures above 30 degrees in almost all federal states. In 20 there were 30 degreesĪpril 2012 was as hot as the middle of summer. Nevertheless, summer was also a short guest, on the 1st of the month it was 26.9 degrees in Güssing (Burgenland). April 2021 was colder than it had been in 24 years. Even individual cold records were set, for example in Windischgarsten in Upper Austria with minus 9.9 degrees and at the airport in Graz with minus seven degrees. Farmers tried to prevent the worst with frost candles and smokers and to protect and warm flowers and plants from the cold. Last year there were an unusually large number of frosty nights in April. Especially on Monday night there is a widespread threat of frost. However, the cold nights can be problematic in the orchards and vegetable gardens. However, the recent rainfall was very important for further growth. The extreme drought had no effect on the apricot blossom, for example, because this is only controlled by the temperature. “Due to the cold first half of March, this lead has reduced to around a week,” says Thomas Hübner from ZAMG. In this extremely warm February, the development of nature was around two weeks above the long-term average. In addition to several frosty nights, it also snowed heavily: 15 centimeters in Klagenfurt and even 31 centimeters in Bad Eisenkappel. In 2016, the annual production of dessert fruit was only a third of a normal year, due to a late onset of winter at the end of April with polar cold air. Climate change is making frost in April more dangerous and damage to crops more likely. The reason: it gets warmer earlier and earlier in February and March, so the plants sprout earlier and the growing season is longer. “Apricots, apples and cherries are now flowering an average of ten days earlier than 30 years ago,” says Thomas Hübner, phenologist at the Central Institute for Meteorology and Geodynamics (ZAMG). Major frost damage in recent yearsĪlthough frost in April is nothing unusual, minus temperatures have repeatedly caused major damage in agriculture in recent years, especially in 2016, 2017, 20. As soon as the current wet and cold weather period ends, the loads will increase again very quickly and herald the main load phase of the birch season, writes the pollen warning service. Some of it has already started this year. Pollen allergy sufferers fear the blossom of the birch. After the apricot blossom, cherries, peach, pear and plum blossom one after the other, and we experience “full spring” with the blossoming of the apple trees and lilacs.įrom one day to the next, trees bloom, here a cherry The trees are getting their leaves and the stone fruit are blooming. And often the weather changes several times within a day, that is the classic April weather. The range of weather in April is not as wide as the whole year: snow, sleet, frost, thunderstorms, but also bright sunshine and real summer heat are in its repertoire. Depending on the direction of the air flow, we can enjoy the warmth once again, and the weather shows its icy shoulder again. ![]() We in Central Europe and thus in Austria are the main arena of this weather dispute between the South and the North. Water is inert and cannot heat up as quickly as land. The North and Baltic Seas have also saved the winter cold. But in the far north the fierce winter still lurks, in the Arctic there is still permafrost. In southern Europe, the summer high is usually already building up in April, from Spain to Sicily to Cyprus the weather is becoming more stable, sunnier and the number of summer days is slowly increasing. This is how the whole continent is heating up – but at an unequal rate, so the contrasts are increasing. The sun, the engine of the weather, shines longer and provides more and more energy, already as much as at the end of August. In Europe, the switchover from winter mode to summer mode takes place in April. From snowfall to permafrost to summer heat and even the first days of swimming, everything is possible in Austria in April, almost every year. The return of winter in some parts of the country over the weekend is a reminder that even in April the weather can be quite cold and unpredictable. ![]()
