Highest temperature in Wellington on August 15?

Platform comparison

Market context

Wellington International Airport will record a maximum temperature on 15 August 2026, measured in the Daily Observations table on Weather Underground rather than summary forecasts. The settlement window closes at 12:00 UTC that day, meaning the highest reading captured at the station by that time determines the outcome. August is Wellington's winter month, with typical highs around 11–13 °C, though extremes occasionally reach 16–18 °C on warmer days.

The 0% crowd probability reflects the market's nascent state rather than meteorological certainty. Historical August maxima at Wellington Airport span a narrow band; the station's 30-year average high sits near 12 °C, with recorded extremes rarely exceeding 17 °C. Comparable winter-month temperature markets in Southern Hemisphere cities show similar clustering around seasonal norms, with outlier temperatures (above 18 °C) occurring in roughly 5–10% of cases depending on the specific threshold band. The current implied odds suggest traders have not yet priced in the full distribution of possible outcomes.

Traders should monitor the MetService 10-day forecast issued in early August 2026, which will clarify whether anticyclonic systems or warm northerly flows are likely to affect the region. The National Institute of Water and Atmospheric Research (NIWA) seasonal outlook, typically released in late July, may signal whether August 2026 is tracking warmer or cooler than the 30-year mean. Weather Underground's data feed occasionally experiences minor delays or corrections; resolvers should verify the Daily Observations table directly rather than relying on cached summary figures. No KYC requirements apply to positions under NZD 1,500 equivalent on most jurisdictions' prediction platforms, though German GlüStV and US CFTC oversight may impose reporting thresholds for larger traders.

FAQ

Do I need to KYC for Is Polymarket Legal in Canada?
