Official forecasts from MetService and aligned models project a maximum of 18°C for Wellington on September 29 under a ridge of high pressure bringing fine, clear conditions with light variable winds shifting southerly. Current observations show temperatures climbing steadily through the afternoon toward this threshold, consistent with spring climatology and recent northerly flow easing. The 99.5% market-implied odds on 18°C reflect trader alignment with these verified guidance products and minimal model spread. An unexpected late surge in northerlies or measurement variance at the official site could still shift the recorded high.
