Official meteorological observations from MetService and NIWA stations, including Kelburn Automatic Weather Station, recorded a daytime maximum of 12°C in Wellington on August 18 under a southerly flow that limited warming despite partial cloud cover. This aligns with mid-winter climatology for the region, where typical highs range 10–12°C amid variable winds and occasional showers. Trader consensus at 100% for 12°C reflects real-time data feeds and model agreement showing no exceedance, with skin-in-the-game positioning reinforcing the outcome. A late revision to official records or an anomalous microclimate spike at the primary resolution station could theoretically alter it, though such adjustments are rare once daily summaries are finalized.

This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the highest temperature recorded at the Wellington Intl Airport Station in degrees Celsius on 18 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Wellington Intl Airport Station, available here: https://www.wunderground.com/history/daily/nz/wellington/NZWN.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °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.
