Recent forecasts from agencies including the German Weather Service and ECMWF models indicate a daytime maximum near 21–22°C in Munich under partly cloudy skies with moderate westerly winds, creating tight uncertainty between those two bins. Primary drivers include surface solar insolation modulated by variable cloud cover, which limits peak radiative heating, alongside advection of cooler maritime air that caps afternoon temperatures. Light winds reduce boundary-layer mixing while urban heat-island effects in the city center add a small positive bias. Model runs show minor spread in timing of any afternoon clearing, directly explaining why trader-implied odds remain nearly even between 21°C and 22°C rather than favoring a clearer outcome. Updated observations through the afternoon will determine final resolution.
