Heatwave Alerts Across Germany: What Expats Need to Know

Introduction

Germany is bracing for a spell of intense summer heat, with official heat alerts issued by the German Weather Service (Deutscher Wetterdienst, DWD) for large parts of the country. Millions of residents are affected, and thunderstorms are forecast to accompany the high temperatures in some regions. For expats — especially those new to Germany or not yet used to navigating public systems during emergencies — it helps to know where to get reliable information and how to protect yourself and your household.

What the Heat Alerts Mean

The DWD issues heat warnings on a colour-coded scale. When a warning is in place, it means temperatures are expected to reach levels that pose a genuine health risk, particularly for older people, young children, people with chronic illness, and those who work outdoors.

During a heatwave alert:

• Avoid strenuous outdoor activity during peak hours, typically between 11:00 and 17:00.
• Keep your home cool: close shutters and curtains on sun-facing windows during the day, open windows at night.
• Stay hydrated: drink water regularly even if you do not feel thirsty.
• Check on neighbours, especially elderly ones — Germany has a strong culture of community support during heat events.

If you work outdoors or in an environment without air conditioning, German labour law gives you rights: employers are required to take protective measures during extreme heat, which can include providing water, adjusting working hours, or — in severe cases — stopping work. If you have concerns, contact your employer or the relevant trade union (Gewerkschaft).

Thunderstorms Alongside the Heat

A common pattern in German summers is that intense heat is followed by strong thunderstorms. The DWD may issue separate warnings for severe storms, including heavy rain, hail, and strong winds. These can disrupt public transport and cause localised flooding.

It is worth downloading the Warnwetter app (free, from DWD) or the NINA app (Germany's official civil protection warning app, available in multiple languages) to receive real-time alerts for your location. Both apps are available in the Apple App Store and Google Play.

Bonn North Bridge Repairs: Two More Years of Disruption

In separate infrastructure news, repairs on the Bonn North Bridge (Bonner Nordbrücke) will take at least another two years to complete. This is significant for anyone commuting into or through Bonn, as the bridge is a major crossing point over the Rhine. Alternative routes are in use but add considerable travel time. If you live or work in the Bonn–Cologne area, plan extra time for road journeys and consider public transport options where possible.

Frequently Asked Questions

Where can I find official heat warnings in English?

The DWD website (dwd.de) publishes warnings primarily in German, but the NINA app offers alerts in several languages. You can also check English-language German news outlets for daily weather summaries. For health guidance in multiple languages, the Robert Koch Institute (RKI) and your local public health office (Gesundheitsamt) are reliable sources.

What are my rights as a worker during a heatwave in Germany?

German occupational health and safety rules require employers to ensure safe working conditions during extreme temperatures. This includes providing sufficient drinking water, offering shaded rest areas for outdoor workers, and adapting work schedules where possible. There is no fixed legal maximum indoor workplace temperature, but the technical guidelines (ASR A3.5) recommend action once temperatures exceed 26°C indoors and mandate measures above 30°C. If you feel your workplace is unsafe, you can contact the relevant state authority (Gewerbeaufsichtsamt) or your union.

Conclusion and Next Steps

Heatwaves in Germany are becoming more frequent and more intense. Knowing how to access official warnings, protect your health, and understand your workplace rights is practical knowledge every expat should have. Download the NINA or Warnwetter app now — before the next alert — and make sure your household is prepared with water, window covers, and a plan for the hottest hours of the day.
