Highest temperature in Wellington on July 14?

Platform comparison

Market context

On 14 July 2026, Wellington International Airport will record its highest temperature for that calendar day, measured in Celsius. Polymarket currently prices all temperature bands at 0%, reflecting the settlement window's distance and the inherent uncertainty in long-range weather forecasting. The contract resolves based on historical data logged at the airport's official weather station, accessible through Wunderground's archives.

Wellington's mid-winter climate in July presents a constrained range for maximum temperatures. Historical records show July highs at the airport typically fall between 10°C and 14°C, with extremes rarely exceeding 16°C or dropping below 8°C. The city's maritime location and southern hemisphere positioning mean winter temperatures remain relatively stable compared to continental locations. Traders should reference the past five years of July data at Wellington Intl Airport to calibrate expectations; the 2025 July maximum, once recorded, will provide the most recent comparable baseline.

The primary catalyst affecting this market's resolution is the Southern Oscillation Index and broader atmospheric patterns developing through early 2026. A strengthening La Niña or persistent high-pressure system could elevate winter temperatures above the historical median, whilst a deep Antarctic polar vortex incursion could suppress them. New Zealand's MetService publishes seasonal outlooks quarterly; the February 2026 outlook will be the final major forecast update before the settlement window closes at midday on 14 July 2026.

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.
