Forecast models from agencies including MetService and international ensembles indicate Wellington's overnight minimum on September 14 will likely settle near 7–8 °C under a high-pressure ridge promoting clear to partly cloudy skies and light northerly winds. Radiative cooling overnight, modulated by dew points around 6–8 °C and modest humidity, drives the tight spread between these thresholds; slightly stronger winds or residual cloud could limit cooling to 8 °C while calmer, clearer conditions favor 7 °C. Historical September climatology shows typical lows near 8–9 °C, but current stable high pressure supports values at or below that baseline. Updated model runs and local observations tonight will refine the precise minimum before market resolution.

The resolution source for this market will be information from NOAA, specifically the lowest 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.
