Current forecasts from multiple models indicate a daytime high of 13–14°C for Wellington on September 17 amid persistent northerly flow, extensive cloud cover, and periods of rain that limit solar heating and cap temperatures. These conditions align with typical spring patterns where frontal systems and orographic effects from surrounding hills moderate extremes, keeping peaks near the seasonal average of roughly 13–15°C. The close market split between 14°C and 15°C reflects uncertainty in the precise timing of any temporary clearing or wind shifts that could allow brief warming, with official guidance from agencies like MetService emphasizing steady precipitation through the afternoon. Updated model runs overnight will provide the key data for traders assessing whether resolution lands at the lower or upper end of the favored range.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Wellington Intl Airport Station in degrees Celsius on 17 Sep '26.
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.Current forecasts from multiple models indicate a daytime high of 13–14°C for Wellington on September 17 amid persistent northerly flow, extensive cloud cover, and periods of rain that limit solar heating and cap temperatures.
