Surviving Germany's Heatwave: Practical Tips for City Life

Introduction

Germany is currently experiencing an intense heatwave, with thermometers potentially climbing to around 40°C in some regions. For anyone living in a German city — whether long-term resident or newly arrived expat — this kind of heat presents real challenges. Unlike many countries, Germany's urban infrastructure was not built with extreme heat in mind: older apartment buildings rarely have air conditioning, public transport can feel suffocating, and asphalt-heavy city centres trap warmth long into the night. Knowing how to navigate these conditions safely is important for everyone, but especially for those unfamiliar with German summers.

Navigating the City Safely in the Heat

The most important principle during a heatwave is to reduce your exposure to direct sunlight wherever possible. Plan your outdoor routes to take advantage of shaded streets, parks with tree cover, and the cooler sides of buildings. Many German cities have old town centres with narrow streets that receive less direct sun — these can be significantly cooler than wide, open boulevards.

Timing matters enormously. If you need to commute or run errands, aim to do so in the early morning (before 10:00) or in the evening (after 19:00). Midday to mid-afternoon — roughly 12:00 to 16:00 — is when UV radiation and air temperature peak. If your employer allows flexible working hours (Gleitzeit), this is a good week to use that flexibility.

Public transport during peak heat can be uncomfortable, particularly older U-Bahn and S-Bahn carriages without climate control. If possible, choose cycling on shaded routes or walking over enclosed underground transport during the hottest hours. Many German cities also have public drinking water fountains — check your city's map or app to locate them in advance.

Staying Cool at Home

Most German apartments — particularly in older buildings — do not have air conditioning. Managing indoor temperature requires a different approach than many expats may be used to. The key technique is cross-ventilation at night: open windows on opposite sides of your apartment after sunset to draw in cooler air, then close shutters (Rollläden) and windows in the morning before the outside temperature rises. This traps the cooler night air inside.

Avoid cooking with the oven or stove during the day, as this raises indoor temperatures significantly. Cold meals, salads, and no-cook options are practical choices. Wet towels on your neck or wrists, cool (not ice-cold) showers, and staying on lower floors — where heat rises more slowly — all help.

If your apartment has no Rollläden, improvising with blackout curtains or even sheets hung inside the window can reduce solar heat gain noticeably.

Health Risks to Know

Extreme heat is a genuine health risk, not just a discomfort. Heat exhaustion and, in severe cases, heatstroke can occur quickly — particularly in the elderly, young children, people with chronic conditions, and those doing physical work outdoors. Symptoms of heat exhaustion include heavy sweating, dizziness, nausea, and fatigue. If these appear, move to a cool place immediately, drink water, and rest.

Germany's public health system (Krankenversicherung) covers treatment for heat-related illness. If you or someone around you shows signs of confusion, stops sweating despite the heat, or loses consciousness, call 112 immediately — these are signs of heatstroke, which is a medical emergency.

Stay well hydrated throughout the day. Aim for at least 2–3 litres of water, and be cautious with alcohol, which accelerates dehydration.

Frequently Asked Questions

Does Germany have official heat warnings, and where can I find them?

Yes. The Deutscher Wetterdienst (DWD), Germany's national weather service, issues official heat warnings (Hitzewarnung) at two levels: a standard heat warning and a strong heat warning. These are published on the DWD website (dwd.de) and through most German news apps. Many city governments also activate heat action plans, opening cooling centres in public buildings such as libraries and community centres.

Am I entitled to work from home or adjusted hours during a heatwave?

German labour law does not automatically grant the right to work from home during heat, but the Arbeitsstättenverordnung (Workplace Ordinance) does require employers to take measures when indoor workplace temperatures exceed 26°C, and to take further action above 30°C and 35°C. This can include providing fans, adjusted break schedules, or allowing flexible hours. If you work in an office that regularly exceeds these thresholds, speak to your employer or your Betriebsrat (works council) if one exists.

Conclusion and Next Steps

Germany's current heatwave is expected to last several days. Taking simple, practical steps — planning shaded routes, adjusting your schedule to cooler hours, managing your apartment temperature with ventilation rather than cooling — can make a significant difference to your comfort and safety. Check the DWD website for daily heat warnings in your region, keep water with you at all times, and check on elderly neighbours or family members who may be more vulnerable.
