Traders have overwhelmingly priced the 9°C outcome at 99.7% implied probability because official MetService and NIWA forecasts for Wellington on August 5 project a daytime maximum near that level under southerly flow, persistent cloud, and temperatures suppressed below the August climatological average of 12–14°C. Real-time observations and model consensus through the morning show readings climbing to but not exceeding 9°C, with wind chill and marine influence limiting further warming. This skin-in-the-game consensus reflects high confidence in the resolution criteria based on verified station data. A realistic challenge would require an unexpected late-day shift in steering patterns or model error allowing readings to reach 10°C or higher before the observation window closes.
