Trader consensus pins a 100% implied probability on Wellington's highest temperature reaching exactly 23°C on March 27, aligned with MetService New Zealand's official forecast and ensemble model consensus showing a daytime peak under a stable high-pressure ridge delivering mild autumn air, light southerly winds, and partial cloud cover that caps warming. Recent 12Z GFS and NZLAM model runs confirm no intensification of onshore flow or clearing skies to enable higher temps, with historical March averages around 21°C providing climatological context for this positioning. Realistic challenges include an unforeseen surge in downslope föhn winds or rapid cloud dissipation, potentially nudging to 24°C, though current atmospheric stability makes this unlikely; final observations from Kelburn station will resolve the market.
