**Forecast consensus from MetService and global models (GFS, ECMWF) supports a maximum of 15°C in Wellington on September 19, 2026.** Northwesterly winds of 20–35 km/h, mostly cloudy skies, and stable synoptic conditions have kept temperatures aligned with the seasonal average near 12–14°C while preventing significant warming. Official outlooks list a daytime high of 15°C with minimal precipitation risk, producing tight market-implied odds at that exact threshold. Late-day observations or minor steering adjustments could push readings to 16°C, but current model runs and station data show little divergence, reinforcing the dominant trader positioning.

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 19 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.**Forecast consensus from MetService and global models (GFS, ECMWF) supports a maximum of 15°C in Wellington on September 19, 2026.** Northwesterly winds of 20–35 km/h, mostly cloudy skies, and stable synoptic conditions have kept temperatures aligned with the seasonal average near 12–14°C while preventing significant warming.
