**Forecast models and recent observations position a 12–13°C high as the dominant outcome for Wellington on September 8.** Southern Hemisphere spring conditions, combined with a stable high-pressure ridge and light northwesterly winds, support modest daytime warming moderated by the cool Tasman Sea. Official guidance from MetService-aligned sources and international models (including GFS and ECMWF runs) consistently project a maximum near 12–13°C under partly cloudy skies, with minimal rain risk and temperatures peaking in the early afternoon. Recent days have featured cooler readings around 10°C amid stronger southeasterlies, but the shift to calmer flow has allowed the market-implied probabilities to concentrate on these values. Historical September averages near 14–15°C provide context, yet current steering patterns and sea-surface temperatures limit upside potential. Updated model runs and any late wind shifts remain the key variables before resolution.

The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=nzwn
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
