**Forecast consensus from major models points to a daytime maximum near 21°C in Amsterdam on August 30, aligning with the market’s heaviest weighting on that outcome and the secondary probability on 22°C.** Persistent southwesterly flow, extensive cloud cover, and scattered showers are expected to limit solar heating under a maritime regime typical of late summer in the region. Official guidance from sources such as the Met Office and Yr.no shows afternoon highs of 20–21°C after overnight lows near 16–18°C, consistent with climatological norms for the date (historical average high ~21°C). Recent model runs have converged on modest warming potential only if breaks in cloud develop, keeping the chance of 23°C or higher low while rendering sub-20°C readings unlikely absent an unforecasted surge of cooler air. Traders are pricing the narrow 21–22°C window heavily because any last-minute clearing or timing shifts in the frontal passage could nudge the peak by 1°C either way before resolution.
