Highest temperature in Wellington on July 14?

Platform comparison

Market context

Wellington Airport's daily maximum temperature on 14 July 2026 will be recorded and bracketed into a range by Wunderground's historical database. July is mid-winter in New Zealand's capital, where typical maxima hover between 11–13°C. The settlement mechanism relies on a single authoritative source—Wunderground's Wellington Intl Airport Station record—making this a straightforward instrumental reading with no discretionary interpretation required.

The 0% crowd probability reflects the market's early stage and thin liquidity rather than a genuine consensus that temperatures will fall outside measurable bounds. Historical July data from Wellington shows maxima rarely exceed 15°C and seldom drop below 8°C, establishing a practical range of 7–16°C across most plausible outcomes. Comparable winter-month temperature markets on Kalshi and Betfair have typically seen tighter clustering around seasonal norms, with outlier ranges trading at decimal odds reflecting genuine tail-risk pricing rather than zero probability.

Traders monitoring this market should note that New Zealand's MetService issues forecasts five to ten days ahead, with updates available through their public portal and via Wunderground's integration. A significant weather system—rare for mid-winter but not unprecedented—could shift expectations materially. The settlement window closes at 12:00 UTC on 14 July, which corresponds to early evening in Wellington; traders should verify whether Wunderground's historical data captures the full calendar day or truncates at a specific local time, as this affects which temperature observation counts for resolution.
