Extreme Weather In Southern Germany June 2021

Peter Engelmann, July 3, 2021

2021: A cold spring with temperatures in May below average. Luckily there was lot of rain in parts of Germany after a drought since 2018 in some areas which damaged trees and raised serious concerns for example about the future of the water balance and water supply. In June a heat wave followed. However unlike in previous years there were no long lasting high pressure systems. The weather situation wasn’t so far stable for a long time. The heat wave ended with some extreme weather events. And again, we had situations for example in South-West-Germany or in Landshut, lower Bavaria, which were unprecedented. There are a lot of discussions now going on if this is climate-change related or if it is another rare weather pattern.

Things began to change in Bavaria June 20, 2021. The days before had been mostly dry except first thunderstorms in the Southwest and in the Alps. On June 20 there were some rumble and not so intense lightning in the region west of lake Ammersee. As usual there are huge local differences: There were soon stronger thunderstorm whereas a few kilometres apart from that place nothing or little happened. That’s very usual and always challenges weather forecasters.

The next days there was a much different weather situation: In the late afternoon or evening real strong thunderstorms occurred. Rotating supercell storms were also reported in the Southern Germany. Even more extreme weather happened in France where an air mass boundary created havoc. In France huge clusters of thunderstorms formed repeatedly and moved to Belgium and North-West Germany.

The extreme weather with strong thunderstorms, flash-floods, even extreme hail with enormous hailstones and masses of hail lasted for a couple of days. The reason: The air mass boundary moved only slowly in Europe. It worked like a machine charging up the atmosphere and creating new thunderstorms. A time-lapse video from June 21, 2021 late afternoon gives you some idea how quickly the storms formed:

It was interesting that there were very different types of thunderstorms. The location southwest of the Ammersee experience short-lived thunderstorms, a thunderstorm which arrived very quickly as the next day there was slow movement and plenty of time to take pictures. In the night there was also one of the “stroboscope”-like thunderstorms, where you hear not much loud thunder but you see an incredible light show with high rates of flashes. There were both thunderstorms without wind and thunderstorms with very strong wind.

The thunderstorm on June 24 created some great lightning:

The storm below occurred June 28, 2021 and brought intense lightning. However it was completely different as the “strobe-storm” the night before before. The lightning was also better visible. After one of the storms there was also a thick mist around sunset. Later the mist vanished and another thunderstorm with strong lightning occurred. The stronger storms came mostly from the Alps.

Flash Floods and Super Cell Storms

Finally there was an exchange of air mass. The hot humid air was replaced by colder air. June 29 was the climax of the series of thunderstorms in Germany: In Bavaria, a super-cell coming from Baden-Württemberg, intensified and brought an incredibly flash flood in Landshut Lower Bavaria. The days before a deadly tornado happened in the Czech republic. The video shows the aftermath of the big storm on June 29 which was accompanied by very strong winds.

Here is also an interesting thing for photographers and videographers: Usually most people are interested to catch a storm coming to them or before it happens. But there is a lot of possibilities to get interesting moods and pictures when the storm passed. The video belows shows what was going on in the atmosphere after this huge thunderstorm on June 29.

Thunderstorms before Sunset

In Upper Bavaria weather changed Sunday, June 28. Along the Allgäu Mountains, intense rainfall began in the afternoon. Thunderstorms with hail occurred in the south-east of Bavaria. The hailstorm pilots near Chiemsee started four times theses days. Clouds and rain created a magical atmosphere around Weissensee not far from the famous Neuschwanstein castle.

Three days later an impressing thunderstorm happened in the early evening hours in South-Bavaria. It was before sunset. Thus there were interesting effects with a colored sky. There were some intense local rainshowers and the weather lasted for more days.

On July 2 a supercell-storm devastated an area around Murnau, which is not far from Garmisch Partenkirchen. Witnesses reported that there was both hail and a flashflood rain at the same time. They could not remember a similar phenomenon happened before. Within 15 minutes streets were flooded and cows had to be rescued from a farm.

Later the week the weather calmed down. This kind of weather is very typical for the season in Bavaria. There is always a change between warm summer days and rain except the last years when a drought happened. Most of the severe storms in Germany happen in July. In 1984 an unparalleled hailstorm led to incredible destruction in Bavaria’s capital Munich.

Intense supercell-storms, hail and flash floods can, however, occur any time between May and September. In June 2019 a hailstorm led to a lot of destruction in the Northern-Ammersee region. In some years there were storms with flooding in May. Storms happen also in August, usually in September heavy thunderstorms are not so often because the days are getting shorter. There is less energy from the sunlight to generate these type of storms however there are weather patterns which could also lead to strong storms in October. In September 2017 lightning hit the Munich Octoberfest.

Thunderstorms with devastating hail happen more often in the south-east of Upper Bavaria rather than in the Allgäu. Usually, the storms develop over the hills and mountains in the West and move to the East. A squadron of Hailstorm pilots, “Hagelflieger” from Vogtareuth protects the area around lake Chiemsee efficiently and gather important scientific information.

A miracle of Nature: Pink Sandstone in the Northern Vosges

Bizarrely shaped sandstone cliffs illuminated by the sun in pink and orange: This is something which you usually expect in the US in national parks in Arizona or Colorado. However, in the middle of Europe located on the Franco-German border, there is a unique landscape with low mountain range forests, rivers, 100 castles and impressive sandstone cliffs. A landscape which was formed by wind and weather and 200 million years old: The UNESCO Biosphere Reserve Palatinate Forest (Pfälzerwald) and Northern Vosges.

The Northern Vosges area is located west of the Rhine in northeastern France. It is not the same as the Vosges mountains or the Haute Vosges. It is the foothills just north of them in Alsace. The regional nature park of the Northern Vosges exists since 1976. It is an extraordinary region with an incredible variety of wildlife. 65% of the area is covered by forest.

A big attraction is the castles which are often located on view-points. These are hills where you have an impressing look and here you often find this intense red-brown coloured sandstone in the French Vosges. It is a mid-grained and pebble bound sandstone which was also important for many buildings as chateaus and cathedrals. The material was formed by wind and weather. The interesting thing is that it looks always different depending on the sun and the conditions of light. It makes a great motive for any photographer. It is also of great interest for anybody interested in geology and history of the Earth. The park was winner 2009 of the Eden competition.

Chateau du Falkenstein: Medieval heritage and a great viewpoint

The chateau du Falkenstein is a great location: It is a ruined castle on top of a hill in the commune of Philippsborg in the Mosélle department. After a walk of 20 minutes from the parking spot, there is great view, the ruins of a once huge medieval castle and very impressing sandstone formations.

The sandstone was indeed part of the castle: The builders carved some caves and rooms in the sandstone rock. The castle was built in 1127 and destroyed in the Thirty Year’s War. However, there is still a lot to see there.

In the Northern Vosges, there is also a place they call “Little Colorado”: This is the Altschloßfelsen in Poppeviller in the Pays de Bitche, a long sandstone Riff. The German pendant of the Northern Vosges is the “Dahner Felsenland” in the Rhineland Palatinate. Tourists visiting France and this region can get information in the “Maison du Parc” in Little Pierre, a cosy village with an impressing chateau. Tourism is important here: Both the communities and other institutions like the Club Vosgien did a lot of work to inform and guide interested visitors:

Train stops are in Sarrebourg and Saverne (TGV Paris-Strasbourg). Important centres are Bitche and Sarreguemines. The Northern Vosges area is also not far from Saarbrücken. The area is great for hiking and offers long-distance trails. It is also a popular region for cycling.

The climate is semi-continental with dry and hot summers and cold winters with a lot of snow. Like many other areas, the region suffered from the heatwaves and drought 2018 and 2019.

The Magic Pools Of Oberstaufen: Buchenegger Wasserfälle

In the South-West of Bavaria is one of the most spectacular places of the Northern Alps located: The Buchenegger Wasserfälle with two huge turquoise pools of water and a strong waterfall of crystal clear water. It is really an impressing sight and an unforgettable experience.

The Buchenegger Waterfall is a wonderful motive for any photographer. Of course, on weekends during summer there are a lot of people around. This is because it’s not only something to watch but there is a five-meters deep pool where people can swim. Most of them, however, leave quickly since even in July and August the water is pretty cold. Furthermore, there are courageous young people who do a 30metre high jump from above the waterfall. It is a bit like Acapulco.

The Buchenegger Wasserfälle is part of an impressing canyon of the river Weissach. The Weissach river is coming from the Hochgrat-Mountain and cascades between two villages Buchenegg and Steibis. Further down the river reaches Oberstaufen, which is a famous and excellent tourist location. There are many hotels and attractions there. The landscape isn’t usually as dramatic as in other parts of the Bavarian Alps. Therefore the canyon of the Weissach and the Buchenegger Wasserfälle is an extreme contrast adding to an unforgettable experience.

Oberstaufen can be reached by train or by car. The trains commute frequently. Oberstaufen is located in the West of the Allgäu not far from Kempten and the Bodensee. It is also close to the Austrian border.




There are two paths leading to the Buchenegger Wasserfälle. One path begins near the parking-space in Buchenegg (a very narrow mountain road is leading there and it is crowded on some days – thus it is not recommended particularly for drivers who are not experienced to drive in mountain areas. Better use the parking spots in Steibis on the other side). There is another reason for this particularly for people who are not experienced hikers. The path is in very good shape but it is very steep. If you are afraid of heights or don’t feel safe walking in such rocky areas use the path coming from Steibis. This is much shorter and is most of the time an easy walk.

You can also use the bus from Oberstaufen to Steibis. The path begins near the stop “Berggaststätte Hirsch”. Before the path enters the canyon, there are two lovely farmed alps. One of them is the Alm Neugreuth, the other is the Alpe Neugschwend. These are very good places to rest and grab some tasty food before hiking down the canyon.

 


Entering the canyon is deeply impressing from the first moment. It is not only the white waters, the cliffs and the waterfall: There is a primaeval forest growing inside the canyon with a huge variety of trees and plants. This adds to the scenery and offers much more attractive motives.

The best time for catching the fantastic atmosphere is during summer even there are a lot of people around. The morning hours are a convenient time to do pictures because it isn’t so much crowded early in the day.

There are a few things to keep in mind when you want to do pictures of the waterfall and the pool: Your camera will often pointing southwards. Thus, in the middle of the day there is backlighting and strong contrast. Furthermore if you get closer to the waterfall or the wind gets stronger there is a misty spray of the waterfall. It happens easily that there are tiny droplets on the lens. Therefore it is good to always check the camera and clean the lens. Of course be careful because the terrain can be slippery.
