Official forecasts from MetService and supporting models indicate a daytime maximum near 14–15°C for Wellington on September 17, driven by a northerly flow shifting to southerly winds amid widespread cloud cover and periods of rain that suppress solar heating. This setup produces conditions close to or slightly above the September climatological average of roughly 12.5–14°C, with precipitation probabilities exceeding 70% limiting further warming. Model consensus shows modest spread around these values, and any late revisions to wind direction or cloud timing could nudge the observed high by 1°C either way before market 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.
