**Forecast models from sources like the GFS and European centers indicate a minimum temperature in Amsterdam on September 1 likely between 12–14°C overnight into early morning, driven by partly cloudy skies, light westerly winds, and building high pressure that limits strong radiative cooling but allows gradual heat loss under clear spells.** This aligns with current ensemble guidance showing overnight lows near 13°C after daytime highs of 18–21°C, consistent with early-September climatology for the region. Trader emphasis on the 10°C-or-below outcome at 45% implied probability, alongside elevated odds around 14–15°C, reflects uncertainty in exact minimum timing and potential model spread from variable cloud cover or wind shifts, though official forecasts favor the mid-teens range with low precipitation risk. Updated model runs and local observations in the next 12–24 hours will refine these probabilities ahead of market resolution.
