Temperatures between 29 and 36 degrees are expected in the coming days, according to meteorologists at weather forecasting service UBIMET.
The expected temperatures are well above the average for this season but UBIMET meteorologist Martin Schreiter said that with the sun now lower in the sky than in July and August, the climate should be more bearable.
“In contrast to the hot periods in July and early August the sun is already somewhat lower and the air now cools down at night much more. This makes the temperatures a lot more bearable,” he said.
Sun worshippers have been told to enjoy as much of the last of the summer sun as they can in the next few days as temperatures are expected to drop again by the end of the week, with potentially even autumnal weather conditions during the first weekend of September.
Warmest July since records began
Summer 2015 saw the warmest July since records began, with August also experiencing over two weeks of undisrupted heat.
"Between the 6th and 14th of August Vienna experienced temperatures above 35 degrees no fewer than nine days in a row. This is remarkable since the previous record of days with these temperatures was just five for the whole summer of 2003,” says meteorologist Josef Lukas.
The highest temperature in August was 38.2 degrees Celsius, recorded in Wolkersdorf in Upper Austria.
Over in Germany, an equally sizzling heatwave is taking place today with some areas experiencing what has been described as "tropical conditions" extending from the Niederrhein (Lower Rhine) region, over Hamburg and Berlin and to eastern Saxony.
