Recent MetService forecasts and supporting model guidance point to a maximum of 13–14°C in Wellington on September 9 under a building high-pressure ridge, with light variable winds shifting to northerlies by afternoon and mostly clear skies. Spring climatology for the region centers on 13–15°C daytime highs, and current ensemble runs show limited spread around these values, with minimal risk of stronger warming or cooling advection. The 65.5% market-implied probability on 14°C reflects trader weighting of the upper end of this narrow forecast range, while the combined 34% on 13°C and 15°C captures residual uncertainty in boundary-layer mixing and exact wind timing ahead of the next front. Updated model runs tomorrow morning will refine the final observed maximum.

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.
