Traunstein starts the weekend with extreme heat – but the situation is likely to change significantly at the beginning of the week.

For Saturday and Sunday, the 7-day forecast predicts up to 35 degrees each day; from Monday, the probability of showers and thunderstorms increases sharply. By midweek, longer periods of rain are possible – with noticeably lower temperatures.

Noticeable change in the weather follows the heat

On Saturday (27.06.), the forecast for Traunstein shows summer peak values: sunny, 35 degrees during the day and 18 degrees at night. 16 hours of sunshine are expected, precipitation is not anticipated (0 percent risk, 0 l/m²). The day thus marks the peak of the current heatwave.

Sunday (28.06.) will also remain very hot at first: again 35 degrees during the day, 21 degrees at night. Unlike Saturday, however, the forecast already indicates a change. It is expected to be partly sunny, with occasional light rain possible. The precipitation risk is 90 percent, the expected amount is 1.1 l/m²; 11 hours of sunshine are planned. For the region, this is a typical warning signal: If the air remains very warm and humidity increases at the same time, the risk of thunderstorms can quickly build up locally.

From Monday (29.06.), the change becomes clear: The forecast mentions occasional showers and thunderstorms, the maximum temperature drops to 26 degrees (20 degrees at night). At the same time, the predicted rainfall increases to 15.8 l/m² with a 90 percent precipitation risk – and only three hours of sunshine remain. The German Weather Service (DWD) regularly points out an increased risk of thunderstorms in Upper Bavaria in its situation assessments for Bavaria during such weather conditions, sometimes with heavy rainfall in a short period. Whether and where there will actually be severe weather is often decided on a very small scale, according to experience.

Heavy rain moves into focus by midweek

On Tuesday (30.06.), the forecast says it will remain heavily overcast, with occasional rain. Temperatures will be 27 degrees during the day and 19 degrees at night. The precipitation risk is 80 percent, 3.5 l/m² is expected; one hour of sunshine is planned.

Particularly striking is the outlook for Wednesday (01.07.): Persistent heavy rain and thunderstorms are possible in Traunstein. The temperature drops to 19 degrees, with 17 degrees expected at night. With 37.1 l/m², it would be by far the wettest day of the forecast, and no hours of sunshine are indicated. Such amounts are especially relevant in everyday life if they fall in a short time: Then streets can be flooded at short notice, underpasses and lower-lying areas fill up more quickly, and thunderstorm gusts can also cause branches to fall. Anyone traveling in the region or working outdoors should therefore especially keep an eye on the short-term DWD warnings around midweek – they are usually more meaningful for specific locations than a general daily forecast.

Likely calmer towards the end of the week

From Thursday (02.07.), the forecast appears more stable again: cloudy but dry with 23 degrees during the day and 15 degrees at night (0 percent precipitation risk, 0 l/m²), plus seven hours of sunshine.

Friday (03.07.) is also expected to remain cloudy and dry – 22 degrees during the day, 16 degrees at night, also 0 percent precipitation risk and seven hours of sunshine.

In summary, Traunstein faces a clear break: after a very hot, sunny weekend, a noticeably cooler and wetter phase follows within a few days, with the focus on showers, thunderstorms, and heavy rain around Wednesday.
