Official observations from Dutch meteorological authorities recorded a daily maximum of 28°C in Amsterdam on May 23, driving the market’s near-certain outcome for that threshold. Late-spring atmospheric patterns featured moderate westerly flow with limited warm-air advection from southern Europe, keeping readings below the levels needed for 29°C or higher. Climatological baselines place typical May highs near 18–20°C, so 28°C represented an above-average but not exceptional peak. Multiple station reports showed no upward revisions, and forecast models from the prior days converged on similar values. Only an improbable data correction or station-specific anomaly could realistically shift the result at this stage.
