Overview

• The DWD has issued warnings for up to 70 liters per square meter and potentially life-threatening rain in regions north of Hamburg and along the coast.
• July’s precipitation totaled 114 l/m², 47% above the 1961–1990 average, and mean temperatures were 1.5 °C above long-term norms while sunshine hours fell below typical July levels.
• Forecasters project showers and thunderstorms to persist through at least August 6, with only tentative prospects for summer warmth around August 8–9.
• A stationary low-pressure system over Scandinavia, reinforced by successive Atlantic troughs, is blocking the high-pressure ridges needed for sustained summer heat.
• Climate researchers attribute recent heavy rainfall and prolonged wet spells to a warmer atmosphere’s increased capacity to hold moisture.
