Overview
- The German weather service (DWD) warns daytime highs will commonly reach 30–36°C and locally up to about 37°C, with the hottest areas in the southwest and Rhine valley and a likely peak early next week.
- Night‑time temperatures are expected to stay high in parts of the southwest with repeated tropical nights that reduce nocturnal cooling and raise health strain in cities.
- The DWD fire‑danger index is at level 4 across wide areas and reaches level 5 locally, prompting regional measures such as ordered aerial forest observation and local bans or limits on open fires and grilling.
- Health authorities note the previous mid‑June heat phase led to roughly 5,100 excess deaths, and officials are urging extra protection for the elderly, chronically ill, and outdoor workers.
- Models point to growing low‑pressure influence and a rise in thunderstorms and humidity toward the end of next week, but the timing and strength of any cooling remain uncertain so authorities urge cautions now.
