Recent forecasts from agencies including MetService and international models indicate a high-pressure ridge building over New Zealand, favoring mostly clear skies and light northerly or variable winds for Wellington on September 24. This setup supports a daytime maximum near 12–13 °C, consistent with late-spring climatology but tempered by residual cool air from preceding southerlies. Trader emphasis on 13 °C (34 %) and 14 °C (22.5 %) reflects model consensus on modest warming under sunny conditions, while the broad distribution across 10–14 °C captures remaining uncertainty from exact wind shifts, boundary-layer mixing, and localized sea-breeze effects. Updated model runs over the next 24–48 hours will likely narrow the range ahead of 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.
