Recent observations at Circuit Zandvoort confirm light rain and damp track conditions immediately before and during the August 23 race start, aligning with the coastal North Sea climate's tendency for sudden showers despite pre-weekend forecasts showing only a 10-30% chance on Sunday. Trader consensus at 99.6% Yes reflects verified precipitation reports from sessions, overriding earlier dry predictions and highlighting how Zandvoort's variable winds and cloud cover often deliver late changes. Even with such high implied probability, resolution could shift if official data shows rain confined strictly outside the 72-lap window or if measurement criteria exclude light drizzle.
