**Persistent mild maritime airflow, extensive cloud cover, and ongoing precipitation are keeping overnight radiative cooling minimal, supporting trader consensus around higher minimum temperatures for September 4 in Amsterdam.** Forecasts from multiple models show daytime highs near 19–21°C under westerly winds of 8–12 m/s, with dew points holding at 15–17°C and relative humidity often above 80–90%. These conditions limit temperature drops overnight, with most guidance pointing to lows of roughly 15–18°C rather than the long-term average near 12°C. Model differences center on the exact timing and extent of any partial clearing late in the period, wind mixing, and rainfall intensity, which could allow slightly more cooling if skies break earlier or less if showers persist. Historical September 4 lows range from 5.5°C (record) to recent values near 13–15°C, but current synoptic setup favors the warmer end of the distribution. With the market showing closely matched probabilities for 17°C (27%), 18°C (33.5%), and 22°C or higher (38%), traders appear to be pricing in this forecast uncertainty around modest overnight cooling under a stable, moist airmass.
