Recent official forecasts from MetService and international models indicate a mild spring day for Wellington on September 18, with maximum temperatures most likely reaching 14–15°C amid northwest winds and partly cloudy skies. This aligns with the historical September average high of roughly 13–15°C and current conditions featuring moderating temperatures after earlier rain and stronger northerlies. Model consensus shows limited variability, with minimal risk of cooler southeasterly flow or significant cloud cover suppressing the peak. Trader positioning reflects this narrow range, as the 15°C and 14°C outcomes together exceed 80% implied probability, while outliers above 16°C or below 13°C remain improbable absent a sharp forecast shift in the final 48 hours.

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 18 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 official forecasts from MetService and international models indicate a mild spring day for Wellington on September 18, with maximum temperatures most likely reaching 14–15°C amid northwest winds and partly cloudy skies.
