Wellington's minimum temperature on August 22 is expected near 10–12°C as strong northwesterly winds and mild advection from a high-pressure ridge suppress radiative cooling under partly cloudy skies. Official forecasts from MetService, ECMWF, and GFS consensus show overnight lows of 51–54°F (10.6–12.2°C), slightly above the August climatological average of ~9–10°C, with limited model spread on wind gusts exceeding 40–50 km/h that mix warmer air. Traders price 11°C highest because ensemble runs cluster there, while 10°C and 12°C reflect uncertainty in exact cloud timing and any brief clearing that could allow an extra degree of cooling before dawn. Lower outcomes below 9°C remain improbable without an unexpected southerly shift.

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 22 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.
