**Latest official forecasts from MetService and aligned models indicate a maximum of 14–15°C for Wellington on September 21, 2026, under partly cloudy skies with strong northerly to northwesterly winds.** These conditions favor the market’s leading outcomes at 15°C (66.5%) and 16°C (25.5%), as northerlies often advect milder air across the region while Cook Strait winds limit extreme warming or cooling. Recent model consensus shows stable springtime temperatures a few degrees above the September average high of ~13–14°C, with minimal precipitation risk and no major frontal passages expected to alter the peak. Traders appear to weight the upper end of the forecast envelope, reflecting typical model spread in windy coastal environments and the narrow 1°C resolution bands. The market will resolve on official observations once the day concludes.

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 21 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.**Latest official forecasts from MetService and aligned models indicate a maximum of 14–15°C for Wellington on September 21, 2026, under partly cloudy skies with strong northerly to northwesterly winds.** These conditions favor the market’s leading outcomes at 15°C (66.5%) and 16°C (25.5%), as northerlies often advect milder air across the region while Cook Strait winds limit extreme warming or cooling.
