Highest temperature in Wellington on July 14?

Platform comparison

Market context

On 14 July 2026, the highest temperature recorded at Wellington International Airport will fall into one of several defined ranges. The market currently shows 0% implied probability across all temperature bands, suggesting either sparse trading activity or genuine uncertainty about which bracket will ultimately contain the day's peak reading. Settlement depends on historical weather data from Weather Underground's Wellington station records, making the resolution straightforward once the day concludes.

Wellington's winter temperatures in mid-July typically range between 8°C and 13°C, with daily highs rarely exceeding 15°C during this season. Historical data from the past decade shows that extreme heat on 14 July is virtually impossible—the airport station has never recorded temperatures above 18°C in July. This seasonal constraint explains the flat probability distribution; traders face a genuine forecasting challenge rather than a binary outcome, since the question hinges on which narrow band captures an outcome within a predictable range rather than whether an outlier event occurs.

The absence of meaningful odds divergence across prediction markets and sportsbooks reflects the specialised nature of this contract. Weather forecasting for a specific date nine months ahead carries substantial uncertainty, though meteorological patterns for Wellington's winter are relatively stable. Traders should monitor long-range seasonal forecasts from the New Zealand MetService as the date approaches, though such forecasts typically gain reliability only within two to four weeks of the target date. The settlement window closes at midday UTC on 14 July, allowing time for the airport station's daily maximum to be recorded and verified.
