Forecast consensus from meteorological agencies, including the Met Office, points to a daytime maximum of 21–22°C in Amsterdam on August 18 under overcast skies, light rain, and moderate westerly flow that suppresses solar heating and aligns with typical mid-August baselines. Numerical weather models show consistent steering patterns and cloud cover capping daytime warming, which explains the near-even market-implied odds for those two outcomes while holding 23°C or higher below 5%. Minor differences in precipitation timing or localized clearing could shift the exact peak between 21°C and 22°C, with updated model runs and real-time observations near the daily maximum likely to resolve remaining uncertainty before settlement.
