Official forecasts from MetService and NIWA project a Wellington daily maximum near 14°C on August 12, 2026, consistent with the market’s 100% implied probability on that outcome. This aligns with August climatology of 12–13°C highs under typical westerly and southerly maritime flows, tempered by a developing front and moderating northerly influence that supports modest warming amid persistent cloud cover and elevated winds. Recent days saw cooler peaks of 10–12°C under stronger southerlies, but updated model runs indicate reduced chill without exceeding the narrow 13–15°C range. Small shifts in frontal timing or wind direction remain the primary variables that could alter the observed peak by 1°C before resolution.

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 12 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.
