Trader consensus on Polymarket closely splits between 20°C (37%) and 21°C (31.5%) for Amsterdam's highest temperature on May 2, reflecting divergent short-range forecast models amid inherent uncertainty two days out. The Royal Netherlands Meteorological Institute (KNMI) latest outlook as of April 30 morning projects a 23°C peak under variable conditions—40% sunshine interspersed with 60% chance of showers or thunderstorms, mainly south and east—with southwest winds at Beaufort 3 potentially aiding warm advection. However, U.S. models like GFS and ensemble spreads indicate 3-4°C divergence, as incoming frontal clouds could reduce insolation and cap highs below 22°C. Above seasonal norms (historical May 2 average ~16°C), key differentiators include precise timing of precipitation and cloud cover; monitor today's 12Z ECMWF update for shifts before official Schiphol Airport measurement resolves the market.
