Trader sentiment for Wellington's March 27 high temperature clusters evenly around 16-22°C due to persistent forecast uncertainty from ensemble models like ECMWF and GFS, which show a mean projection of 19-20°C but with spreads exceeding 4°C amid variable southerly winds and sea breeze effects. MetService's latest outlook favors 20-21°C under a high-pressure ridge enhancing solar insolation, yet historical March data from NIWA reveals a standard deviation of 2.7°C for late-summer highs, often differentiated by cloud cover variability and coastal moderation. Lower odds for extremes reflect climatological baselines, with 15°C or below rare (5% historical frequency) absent cold fronts, while 25°C+ requires unusual northerlies. Upcoming 12-hour updates will likely sharpen consensus.
