Official hourly observations from Wellington International Airport (station NZWN), the market's resolution source via Weather Underground, confirm the highest temperature reached 21°C this afternoon around 2:00 pm local time, with subsequent readings cooling to 17–19°C amid thickening cloud cover, fresh northerlies, and isolated showers per MetService updates. This peak aligns with model consensus from NIWA and MetService, reflecting warmer-than-average April conditions (historical highs typically 16–18°C) driven by northerly flow ahead of a frontal system. Trader sentiment reflects this skin-in-the-game certainty, as the sun sets with no realistic window for exceeding 21°C barring an extraordinary late-day heat burst or rare data revision—both highly improbable given current atmospheric stability and diurnal cycle. Final daily history expected on Weather Underground within 24 hours.
