Pronóstico: Highest temperature in Wellington on July 25?

Platform comparison

Market context

Wellington's highest temperature on 25 July 2026 will be recorded at the airport weather station and resolved against historical data from Wunderground. The market currently prices all temperature ranges at 0% on Polygon, reflecting the distance of the event and the difficulty in pricing weather outcomes nearly two years forward. Traders settling conditional tokens on this contract will need USDC to enter positions, with resolution tied directly to the official station reading at Wellington International Airport.

July is Wellington's coldest month, with historical highs typically ranging between 11–13°C. The city's southerly latitude (41°S) and maritime exposure create consistent winter conditions, though occasional föhn winds from the north can drive temperatures several degrees above seasonal norms. A review of Wunderground's historical records shows July highs have occasionally reached 16–17°C during warm spells, though readings above 14°C remain uncommon. These patterns establish the baseline against which the market's temperature brackets should be evaluated.

The New Zealand MetService publishes seasonal outlooks and long-range forecasts that traders should monitor as 2026 approaches. El Niño or La Niña conditions, typically announced by NIWA (National Institute of Water and Atmospheric Research) in the months preceding winter, influence whether July temperatures skew warmer or cooler than the 30-year average. Any significant climate pattern shift announced in late 2025 or early 2026 would provide material information for position-building, though the settlement window's specificity to a single day limits the utility of broad seasonal predictions.
