Recent forecast runs from the European Centre for Medium-Range Weather Forecasts and the Royal Netherlands Meteorological Institute indicate a daytime maximum of 19°C in Amsterdam on May 21, driven by a stable high-pressure system and northeasterly flow that limits warming. These models show strong consensus on this value, with minimal spread in ensemble outputs and no significant diurnal heating expected under partly cloudy skies. Trader positioning at 100 percent for 19°C reflects this high-confidence guidance, though an unexpected shift in cloud cover or wind direction could allow readings to reach 20°C before markets resolve at midnight local time.
