Forecast models from sources including GFS indicate Munich will reach a daily maximum of 19–21°C on October 3 under high pressure near 1030 hPa, light northeast winds, and a mix of morning overcast transitioning to partly cloudy skies that permit modest solar heating. This exceeds the early-October climatological average high of roughly 14–16°C, supporting market-implied probabilities concentrated on 20°C and 21°C. Afternoon observations and short-range updates showing temperatures climbing through the upper teens have reinforced trader focus on this narrow band, while limited model spread and absence of stronger warming or cooling signals keep the 22°C outcome as a secondary possibility.
