Recent ensemble forecasts from models including ECMWF and GFS show variable overnight conditions for Wellington on September 14, with predicted lows clustering around 7–9°C amid northerly winds and partial cloud cover that limit radiative cooling. These align closely with long-term September climatology, where average minimums reach about 8°C, yet small shifts in wind direction, humidity, or clearing skies could push readings lower or sustain milder values near 10°C. Trader consensus across tightly bunched outcomes reflects this genuine forecast spread and the limited time until resolution, with fresh model runs and official MetService updates expected to refine probabilities ahead of the overnight minimum.

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.
