Trader consensus on Polymarket has locked in a 100% implied probability for a highest temperature of 20°C at Wellington International Airport on April 12, driven by MetService's 9:21 a.m. forecast update confirming this maximum amid persistent light rain, extensive cloud cover, and easterly winds suppressing daytime heating. Observational data from early morning shows temperatures hovering around 17°C with high humidity and fog, aligning with model consensus from global forecasts like those from the World Meteorological Organization, which project a 15–20°C range under these autumnal conditions typical for Wellington's maritime climate. Historical April averages sit at 15.5°C maximum, making 20°C plausible but not extreme. Realistic challenges would require sudden clearing skies for enhanced solar insolation or a southerly wind shift boosting advection, though low-level moisture limits such upside; final observations expected by evening from the airport station will resolve the market.
