Wellington's overnight low on August 31 is expected to hinge on a shift to strong northwesterly winds and variable cloud cover, which models indicate will limit radiative cooling compared to calmer conditions. Current forecasts from MetService and international agencies point to a minimum near 5–8°C, with partly cloudy skies and possible showers reducing the chance of deeper drops below typical late-winter baselines around 9°C. Trader sentiment clusters around 9–11°C because small changes in wind timing or cloud persistence—common in Wellington's exposed coastal setting—can shift the exact hourly minimum by 2–3°C, while the modest probability on extremes reflects limited historical precedent for outliers this late in August. Updated model runs and local observations over the next 48 hours will likely tighten the range.

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.
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.
