Trader consensus on Polymarket heavily favors a high of 20°C or above in Wellington at 38.5%, driven by MetService's latest forecasts projecting a maximum of 21-22°C on March 26 under a stable high-pressure ridge promoting clear skies and light northerly winds. Historical March data from NIWA shows average maxima of 19.5°C, with 20+°C occurring in 45% of recent years during similar synoptic patterns. Recent developments include yesterday's 21°C reading and GFS/ECWMF models converging on mild warmth, though southerly shifts could cap it at 19°C (23.5% odds), introducing uncertainty as ensemble spreads widen toward evening. Lower outcomes reflect rare cool spells from frontal activity.
