Trader consensus on Polymarket assigns 100% implied probability to a highest temperature of 20°C in Wellington on April 11, 2026, driven by official observations from Wellington International Airport (NZWN station), the market's resolution source via Weather Underground finalized data. Late-afternoon readings peaked at 19-20°C under high cloud cover and light northerlies, aligning with MetService and NIWA model consensus that capped intensification amid diminishing sunlight; earlier forecasts of 22°C proved optimistic as cooler sea breezes moderated peaks. This reflects skin-in-the-game assessment of real-time METAR reports and hourly data, consistent with April climatology averaging 17°C highs. Realistic challenges include rare post-sunset measurement revisions or overlooked microsite warming, though improbable given current cooling to 16°C and market nearing resolution.
