Forecast models from sources such as the Global Forecast System indicate a daytime maximum near 22°C in Munich on October 4, driven by partly cloudy conditions, light northeasterly winds, and daytime heating under high pressure. This exceeds the 1991–2020 climatological average high of 16.7°C for the date, reflecting a warmer-than-normal air mass. Real-time observations through the afternoon have tracked closely with these projections, reinforcing trader consensus around the 22°C threshold. Late-day cooling or minor model adjustments from updated runs could still shift the official recorded high, particularly if increased cloud cover or localized effects alter peak readings before sunset.
