Recent forecast updates from the Royal Netherlands Meteorological Institute and European Centre for Medium-Range Weather Forecasts models show a daytime maximum near 19°C for Amsterdam on May 21, supported by southerly airflow and mostly clear conditions that limit overnight cooling. This consensus, consistent with late-May climatology where average highs reach 18–19°C, positions 19°C as the leading outcome while keeping 20°C close behind if insolation strengthens slightly. Short-range observations through midday confirm temperatures climbing toward these thresholds without exceeding them yet, and any late-afternoon sea-breeze moderation could cap the peak below 21°C. Traders are weighting these model runs heavily ahead of final official readings.
