Official MetService observations from Wellington International Airport station—the market's resolution source—confirm a peak temperature of 16°C reached around midday on April 27, under fine skies with light northeasterly winds, solidifying trader consensus at a 100% implied probability for this outcome. Updated hourly data shows temperatures declining since early afternoon amid rising cloud cover and sea breeze influences, aligning with forecast model consensus projecting minimal daytime heating in this near-average autumn air mass (historical April highs average 17°C per NIWA records). A realistic challenge would require an improbable late surge from sudden downslope föhn winds clearing skies before sunset at 5:36pm NZST, though current trajectories preclude this; final daily maximum posts after midnight NZST.
