Recent short-range forecast models from agencies including MetService and international ensembles indicate Wellington will experience a mild early-spring day on September 1, with daytime highs most likely reaching 12–13 °C under northwest winds and mostly clear to partly cloudy skies. This consensus, supported by current surface observations showing temperatures climbing from overnight lows near 7–9 °C, positions 14 °C as the modal outcome while leaving room for 13 °C if mixing remains limited or cloud cover increases. Historical September averages near 15 °C provide context, yet the specific synoptic pattern favors values clustered around the market’s leading 14 °C (63.5 %) and 13 °C (15 %) bins, with only modest upside risk to 15 °C. Updated model runs tomorrow morning will refine the exact maximum before resolution.

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 1 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.
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.Recent short-range forecast models from agencies including MetService and international ensembles indicate Wellington will experience a mild early-spring day on September 1, with daytime highs most likely reaching 12–13 °C under northwest winds and mostly clear to partly cloudy skies.
