**Market-implied odds heavily favor a 13°C daily minimum in Amsterdam on October 13, reflecting consensus from numerical weather prediction models such as GFS and ECMWF runs.** These indicate mild autumn conditions with light westerly to southwesterly winds, persistent cloud cover, and limited radiative cooling overnight, keeping the lowest temperatures near 12–13°C after daytime highs around 18–19°C. Official observations and short-range guidance align with this range, consistent with climatological norms for mid-October in the region. Traders’ strong positioning incorporates the high implied probability from these stable forecasts. A realistic shift could occur with unexpected clearing skies enhancing nocturnal cooling or revisions in boundary-layer parameterization that lower the minimum below 12°C before resolution.
