Current forecast guidance from MetService and global models points to a minimum near 11–12°C in Wellington on August 28, driven by strengthening northerly winds ahead of an approaching frontal system that will bring cloud, showers, and mild maritime air. Recent days have featured above-average temperatures (daily means 1–3°C warmer than the 10.3°C August norm), limiting radiative cooling overnight despite the winter season. Key variables differentiating the closely matched 12°C and 13°C outcomes include exact timing of cloud cover and precipitation, wind gust strength (which can suppress or enhance mixing), and any late clearing that allows brief additional cooling. Updated model runs and official observations through August 27 will narrow the range ahead of 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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary 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.
