Overview
- After a short cooldown, forecasts show rising temperatures from about July 8 with heat spreading from the southwest toward the rest of the country.
- The German Weather Service's 10‑day outlook points to highs near 35°C in affected areas while some models allow local peaks higher than that.
- The European ECMWF model projects a blocking 'Omega' high holding through roughly July 14 that would bring widespread 27–35°C across Germany and occasional tropical nights in the south.
- The American GFS model depicts a more unstable pattern with repeated disturbances that still permit local spikes up to about 38°C but raise the risk of strong, sometimes stationary, summer storms.
- Meteorologists say the greatest uncertainty starts after July 14–15, and they warn that repeated hot spells would worsen drought, threaten forests and crops, and could make new temperature records possible.
