Current forecast models indicate an overnight low near 10–11°C for Amsterdam on September 25 under clear to partly cloudy skies, light southerly winds, and high pressure favoring moderate radiative cooling after a daytime high around 20°C. This aligns with the recent September pattern of above-average temperatures and typical early-autumn minima, though small shifts in cloud cover, wind speed, or advection could alter the exact low by 1–2°C. The closely matched market odds on the 5°C-or-below and 15°C-or-higher brackets reflect residual uncertainty in model runs two days out, while the clustered probabilities around 9–11°C capture the most likely range based on ensemble consensus and historical climatology for the date.
