Recent model consensus from agencies like MetService and ECMWF points to a daytime high near 11°C in Wellington on September 23, driven by persistent southerly winds behind a passing front that advect cooler maritime air and increase cloud cover with scattered showers. These conditions suppress maximum temperatures below the long-term September average of around 13–14°C, as southerlies enhance mixing and limit solar heating under the region's typical westerly regime. Ensemble spreads remain modest but highlight sensitivity to exact frontal timing and any brief northerly shift, with official updates expected in the next 24–48 hours to refine the peak reading used for market resolution. Trader positioning around 11–12°C reflects this data-driven outlook amid inherent forecast uncertainty.

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 23 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.Recent model consensus from agencies like MetService and ECMWF points to a daytime high near 11°C in Wellington on September 23, driven by persistent southerly winds behind a passing front that advect cooler maritime air and increase cloud cover with scattered showers.
