Official KNMI observations from Amsterdam Airport Schiphol—the market's authoritative measurement station—confirm the highest temperature on April 14, 2026, peaked at precisely 15°C around mid-afternoon, driving the 100% market-implied probability for this outcome. Morning dense fog under a code yellow advisory delayed warming, while intermittent clouds and light southwest winds capped daytime heating under high-pressure influence, aligning with ensemble model guidance from the prior 48 hours projecting 14–16°C maxima. This trader consensus, backed by real capital, reflects verified in-situ data with minimal uncertainty; realistic challenges would require rare post hoc revisions from instrument calibration errors or quality control anomalies, as per KNMI protocols.
