MetService observations at Wellington International Airport (NZWN) confirm the highest temperature on March 28, 2026, peaked at 22°C during the afternoon, aligning with the agency's morning forecast of 21-22°C under cloudy conditions with patchy drizzle and gusty northerlies (35 km/h, gusts to 44 km/h). Partial cloud cover and onshore flow limited solar heating, preventing stronger convective warming despite brief fine breaks. This observed maximum, coupled with historical March averages around 20°C, drives near-unanimous trader consensus, as real-money positions price in the data's reliability. A late-evening surge to 23°C+ would require unforecast rapid clearing and föhn-like downslope acceleration, improbable given current pressure gradients (1015 hPa) and low solar angle. Final hourly data expected by midnight.
