Austria will enjoy a typical summer weekend coming up in the next few days, with temperatures above 30C, sunny days and afternoon thunderstorms, according to the forecast by the country’s weather agency, ZAMG.

The volatile weather will last throughout the Donauinselfest weekend, with visitors to Austria’s largest free open-air festival having to prepare for hot sunny days and storms in Vienna.

On Friday afternoon, most of the country will see high temperatures reaching 30C and thunderstorms during the evening and night, including in the city capital.

Saturday morning will still be a bit rainy in the east of the country but only overcast in the south and west. Temperatures will reach 28C. During the afternoon, only Vienna and Burgenland should see rainfall, but temperatures continue high, with thermometers marking from 25C to 28C.

Sunday will be sunny and hot all over Austria, with some residual clouds during the day. In Vienna, temperatures will pass 30C, so festival-goers beware of the heat. Local showers are not excluded in the mountain, but should be an exception.

A heatwave should hit Austria, especially in the east, on Monday. Temperatures will reach 36C degrees on the day in Vienna and should be over 30C everywhere in Austria. Rain is only expected by the Alps, though, and very little wind should ease the hot day.

Tuesday is also hot throughout the country, with the east seeing up to 36C degrees during the day. Thunderstorms are expected in the West and north of Austria in the afternoon.

Extreme weather warning

Austria’s ZAMG has issued an extreme weather warning for Vienna and the surrounding region on Saturday when thunderstorms are expected.

On Sunday, the weather warning is for extreme heat and covers the east of Austria, including Vienna, Burgenland, and Graz.

On Monday and Tuesday, the entire country is under extreme weather warning for heat, according to ZAMG.

MAP: Where will storms hit Austria this weekend?

After five people died in severe storms on Thursday August 18th, Austria's meteorologists warn of more rainfall and strong winds over the weekend. Here's what you need to know.

MAP: Where will storms hit Austria this weekend?

Five people died when strong winds uprooted several trees in the southern states of Austria, and storms are forecast to hit the country this Friday (August 19th) and Saturday (20th), according to weather agency ZAMG.

This Friday, there are warnings for thunderstorms, rain, and heat in most of the country – especially the east and south. You can check ZAMG’s warning map here:

Weather warnings for Friday, August 19th (ZAMG)

The highest alert now in place is in the orange areas (close attention warning), where the “current weather can lead to risks, disturbances to everyday life and damage. Pay close attention to the ongoing weather forecasts”.

The yellow areas (caution warning) are places where “caution in the current weather circumstances is urged, but only isolated weather-related risks and/or damages are expected”, according to ZAMG.

It should continue to rain during the night in the west of Austria, especially near the Alps. In the rest of the country, the weather is also temporarily unstable and some rain, showers and thunderstorms are expected at night – reaching the far east then.

Rain but fewer thunderstorms on Saturday

On Saturday, the weather forecast is still for rain in most parts of the country, especially on the northern side of the Alps between Vorarlberg and Salzburg.

Later in the day, the rain should affect the eastern part of Austria, where it will be warmest, with temperatures of up to 28C expected.

Extreme weather alerts (attention warnings) are in place for the east of Austria, including Vienna and surroundings and Burgenland and the Innsbruck and Salzburg regions.

On Sunday, there are still some residual clouds – and, therefore, possibly some rain, but no forecast for thunderstorms or any extreme weather warning by the ZAMG.

What to do in case of severe storms?

According to Die Helfer Wiens (The Helpers of Vienna), one of the most significant risks during a storm is being hit by a falling tree or flying debris.

For this reason, they advise people (and pets) to stay indoors during a storm as well as to close all windows and doors.

If staying in a tent or campervan, it’s also advisable to seek shelter in a building (if possible) until the storm has passed.

The same goes for those walking or driving, and authorities say the best advice is to stay away from the forest or areas with lots of trees during a storm.

Don’t underestimate the risks. The recent deadly storm lasted only for ten minutes but caused destruction in valleys and just a few (but strong) gusts of wind had fatal consequences.

Even if there was no extreme weather warning for your region, take the necessary care – Thursday’s thunderstorm in Carinthia came with no warning due to an extremely rare mixture of factors. The atypical heat led to even stronger winds.

“To a certain extent, thunderstorms are unpredictable”, said ZAMG Klagenfurt head Christian Stefan. As a result, the weather institute had only a yellow warning for the southern Carinthia region early on Thursday.
