**Trader consensus has coalesced around a 17°C peak for Wellington on August 25, 2026, reflecting real-time observations of northerly flow advecting milder air under partly cloudy skies.** Official and private station reports show a daytime maximum reaching approximately 17°C (63°F) amid gusty northwesterlies of 20–30 knots, consistent with late-winter patterns where transient ridging and downslope warming can briefly elevate temperatures 3–5°C above the August climatological mean of ~12–13°C. Model guidance from MetService and international ensembles aligned on this threshold without significant spread, and live station data confirmed the high before evening cooling set in. Uncertainties remain modest but include potential revisions from the official MetService or NIWA station reading if localized cooling from increased cloud cover or a frontal passage occurred earlier than anticipated; any such adjustment would need to fall outside the 16.5–17.5°C band to alter resolution.

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 25 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
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.**Trader consensus has coalesced around a 17°C peak for Wellington on August 25, 2026, reflecting real-time observations of northerly flow advecting milder air under partly cloudy skies.** Official and private station reports show a daytime maximum reaching approximately 17°C (63°F) amid gusty northwesterlies of 20–30 knots, consistent with late-winter patterns where transient ridging and downslope warming can briefly elevate temperatures 3–5°C above the August climatological mean of ~12–13°C.
