Recent ensemble forecasts from the ECMWF and GFS models indicate a maximum temperature of 19–20°C in Munich on May 18, driven by a weak high-pressure ridge promoting modest diurnal heating under partly cloudy skies and light westerly flow. This places the market-implied odds tightly clustered around those brackets, reflecting the narrow uncertainty range typical for a near-term spring forecast. Mid-May climatological normals for the region hover near 18°C, so the current setup sits slightly above average but remains sensitive to afternoon boundary-layer mixing and any increase in low-level cloud cover that could cap the peak. The Deutscher Wetterdienst will issue its final guidance within 24 hours, offering the last model refinement before resolution based on the official Munich Airport observation.
