Recent MetService forecasts for Wellington on August 30 indicate a mainly fine day with northwesterly winds and a daytime high near 16°C, aligning with the market's leading 17°C and 16°C outcomes at combined implied probabilities exceeding 70%. Northwesterlies often advect milder Tasman air masses, while clearing skies after recent showers support greater insolation and surface warming in late winter. August 2026 observations already show a modest +0.5°C departure from the 10.3°C monthly normal, with recent maxima reaching 17°C, reinforcing trader focus on the 16–18°C band. Model consensus from sources like Ventusky and international guidance remains tightly clustered around these values, though minor forecast revisions or local topographic effects could shift the official Kelburn reading.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Wellington Intl Airport Station in degrees Celsius on 30 Aug '26.
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 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.Recent MetService forecasts for Wellington on August 30 indicate a mainly fine day with northwesterly winds and a daytime high near 16°C, aligning with the market's leading 17°C and 16°C outcomes at combined implied probabilities exceeding 70%.
