Trader consensus on Polymarket assigns a 100% implied probability to a highest temperature of 16°C at Wellington International Airport on April 25, driven by official hourly observations from the automated weather station, which peaked at this mark midday under mostly sunny skies and developing northerly winds advecting mild maritime air. This aligns precisely with MetService's extended forecast issued April 22, projecting a 16°C maximum amid stable autumn conditions consistent with NIWA's near-average seasonal outlook for April highs around 15–17°C. Historical climatology supports this, as Wellington's April average daily maximum is approximately 16°C. Realistic challenges include an improbable late-afternoon clear-sky heating spike or northerly surge before sunset, but declining solar angles and model consensus indicate low risk, with final daily summaries expected from MetService shortly after midnight.
