Trader consensus on Polymarket favors a Wellington high of 21°C at 45.5% implied probability, driven by MetService's latest forecast models projecting mild autumn conditions under a high-pressure ridge suppressing temperatures. Recent observations show daily highs averaging 20-22°C over the past week, with no significant warm air advection or frontal activity to push toward 23°C or higher (just 6.4%). The 22°C outcome at 23.5% reflects potential for slight model upside from northerly winds, while 20°C (16.5%) accounts for possible cloud cover. Ensemble forecasts indicate low volatility, but a fresh model run expected tomorrow could refine these odds as March 28 nears. Historical March norms (average 20.5°C) align with this clustering around 21°C.
