Trader consensus heavily favors 21°C (43%) as Wellington's high on March 23, driven by MetService's latest forecast predicting a maximum of 21°C under partly cloudy conditions with moderating southerlies following recent warmer spells. This aligns with March climatology—historical averages hover around 20.6°C at Wellington Airport, the market's resolution station—while ensemble models from NIWA show tight clustering between 20-22°C amid neutral ENSO influences. Recent developments include a downward revision from 22°C earlier in the week due to a cool front, tempering odds for 23°C+ (3.8%) and boosting 20-22°C probabilities; traders eye tomorrow's 1200 UTC update for potential shifts before official observations.
