Recent northwesterly flow and associated warm advection have positioned Wellington for a September 6 maximum near 15°C, with ensemble guidance from sources including MetService and international models showing afternoon peaks of 14–17°C under partly to mostly cloudy skies. Strong winds gusting above 30 knots may enhance mixing and limit further warming, while a 50% rain chance could cap the high if showers arrive earlier than anticipated. Historical September averages near 14–15°C provide context, and traders appear to weight the 15–16°C outcomes most heavily given stable model agreement through the latest runs, with resolution depending on the precise daily maximum recorded at official stations.

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.
