**Trader sentiment for Wellington's September 19 minimum temperature centers on model consensus around 7–9 °C amid a transitional spring pattern.** A recent cold front delivered cooler air and South Island snow before yielding to strong northwesterlies and variable cloud cover over the North Island. Overnight lows will hinge on radiative cooling under partly cloudy skies, modulated by wind-driven mixing from brisk northerly flows and any lingering moisture that limits clear-sky heat loss. Ensemble guidance shows modest spread in boundary-layer temperatures, with slight differences in frontal timing or wind gusts separating the leading 9 °C (30 %), 8 °C (26.5 %), and 7 °C (20 %) outcomes. Historical September minima near 8–9 °C provide context, while updated MetService and global model runs through the weekend remain the key near-term catalysts.

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.
