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 2 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 which 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 can not resolve until the first data point for the following date has been published on the resolution source. 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 forecast guidance from Met Office and WeatherBug points to a maximum of 14–15 °C in Wellington on September 2, consistent with early-spring climatology where daily highs average near 13–14 °C. Moderate northwest winds ahead of a weak front are expected to limit daytime warming despite mostly sunny conditions, while overnight lows near 10–11 °C keep the diurnal range typical for the season. Model consensus shows no significant warm advection or blocking high that would push readings toward 17 °C or higher. Trader emphasis on 16 °C therefore reflects residual uncertainty around exact station readings and wind effects rather than a strong signal for warmer outcomes, with resolution dependent on official MetService data.
