Recent forecast consensus from models including ECMWF and MetService indicates a maximum of 15–16°C for Wellington on September 14 under partly cloudy skies, light northerly winds, and negligible precipitation risk. Stable high-pressure influence and typical spring insolation support modest daytime warming above the long-term September average near 13°C, with limited model spread reducing upside potential for 17°C or higher. Official observations from stations such as Kelburn will resolve the market, and traders have priced the 16°C outcome as the clear leader at 53% implied probability given the current guidance.

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.
