Forecasts from sources including the Met Office, BBC, and timeanddate.com indicate Amsterdam's overnight low on August 25 will likely fall between 12–15°C, driven by moderate easterly winds, limited cloud cover overnight, and radiative cooling under clearing skies that allow surface heat loss. Model consensus shows modest variability in exact minimum timing and strength, with urban heat-island effects and precise wind speeds differentiating outcomes near 11–13°C from slightly warmer readings. Traders assign the highest implied probabilities to 11–13°C because recent ensemble runs favor stronger nocturnal cooling than seasonal averages, though small shifts in cloud timing or wind could push the low above 14°C or below 10°C. Updated model guidance expected in the next 24–48 hours will likely refine these narrow ranges ahead of market resolution.
