Overview
- The German Weather Service forecasts clear, dry nights with local lows near −1 °C in eastern areas and close to the Alps.
- Daytime temperatures are set to jump, with some forecasts pointing to highs around 26 °C in the coming days.
- Meteorologists say an early polar vortex breakdown likely shifted any late cold spells forward this year, and they expect the current warm phase to hold into early next week.
- Medium‑range models point to a broader temperature rise from the second week of May, which lowers the chance of a major cold snap then.
- Gardeners are advised to wait on frost‑sensitive plants or protect them overnight, since the traditional Eisheiligen dates are imprecise guides and local microclimates can still trigger frost.
