Forecast consensus from MetService and international models, backed by high-pressure ridging and northwest advection of milder maritime air, has locked trader sentiment on a 15°C maximum at Wellington International Airport on August 29. Real-time observations and hourly guidance show daytime peaks stabilizing near 13–14°C under mostly sunny to partly cloudy skies with 20–30 km/h winds, aligning closely with late-winter climatology while the ridge suppresses cloud cover that would otherwise limit solar warming. This produces the market’s overwhelming 100% weighting on 15°C, as the resolution criteria hinge on the single highest NOAA station reading. Only an unexpected late-day surge from stronger insolation or a model shift introducing warmer advection could realistically push the peak to 16°C or higher before resolution.

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