Current forecast models from MetService and international agencies project Wellington’s daily minimum temperature on August 21 to reach 8°C, consistent with seasonal norms for late winter in the region. Northerly airflow and partly cloudy skies are limiting overnight radiative cooling while keeping conditions near the long-term average low of approximately 8–9°C. Recent NIWA outlooks note near-average temperatures overall for August, with no strong cold-air advection expected today. Trader consensus at 98% for 8°C reflects this model agreement and real-time observational data. A stronger southerly shift or clearer nocturnal skies could allow brief drops toward 7°C, though current guidance shows low probability of such changes before resolution.

This market will resolve based on the lowest 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 lowest temperature recorded at the Wellington Intl Airport Station in degrees Celsius on 21 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the lowest 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.
