Trader sentiment clusters tightly around 18–20°C for Wellington's highest temperature on March 26, reflecting MetService's latest short-range forecast pinpointing a maximum near 19°C amid a high-pressure ridge fostering mild autumn conditions. Ensemble models like GFS and ECMWF diverge modestly—some projecting enhanced insolation for 20°C+ under clearer skies, others cooler advection from southerlies capping at 18°C—yielding market-implied odds of 35.5% for 19°C, 29.5% for 18°C, and 18.5% for 20°C or higher. Historical March maxima average 19.5°C, but diurnal variability and coastal fog introduce uncertainty, with key resolution hinging on morning cloud burn-off observed in prior similar setups.
