Highest temperature in Wellington on July 14?

Platform comparison

Market context

Wellington's maximum temperature on 14 July 2026 will be recorded at the International Airport weather station and resolved against historical data from Wunderground. July sits firmly within Wellington's winter season, when the city typically experiences its coldest conditions of the year, with daily highs averaging around 11–13°C. The 0% crowd probability suggests traders are pricing in an expectation that the day will fall within a defined temperature range, though the specific range boundaries have not yet been disclosed in this market structure.

Wellington's winter weather patterns are shaped by its exposed coastal position and latitude (41°S), making temperature extremes relatively uncommon compared to inland New Zealand centres. Historical July records at the airport show daily maximums rarely exceed 15°C, whilst sub-5°C highs occur sporadically during cold fronts. The settlement window closes at midday on the day itself, meaning traders must rely on medium-range forecasts (currently 18+ months out) rather than observed conditions. Any significant atmospheric pattern shift—such as an early spring warming or an unusual polar outbreak—would move probabilities, but such events are difficult to predict at this temporal distance.

Traders should monitor seasonal climate outlooks from MetService and NIWA as 2026 approaches, particularly any signals regarding La Niña or La Niña-adjacent conditions, which influence New Zealand winter severity. The actual resolution will depend entirely on the recorded maximum at Wellington Airport on that specific date, with no discretionary interpretation involved once Wunderground data is published.
