Trader consensus on Polymarket heavily favors a Wellington high of 21°C (33%) or 20°C (28%) for March 24, driven by MetService New Zealand's latest forecast projecting a maximum around 20-21°C under fine spells with southerly breezes moderating warmth from high pressure. Ensemble models like ECMWF and GFS show tight clustering in this range, with slight bullish tilt toward 21°C from urban heat island effects and potential afternoon clearing, versus 20°C if persistent cloud or sea breezes prevail—historical March averages sit at 20.1°C, amplifying model divergence. Lower odds for 22°C+ reflect low risk of northerly föhn winds, while sub-19°C outcomes hinge on unexpected southerly intensification; watch evening updates for refined probabilities ahead of measurement at Wellington Airport.
