Highest temperature in Wellington on July 20?

Platform comparison

Market context

Wellington’s highest temperature on 20 July 2026 will be recorded at the Wellington International Airport Station, with settlement dependent on Wunderground’s daily maximum in degrees Celsius. The crowd-implied 0% YES probability suggests traders expect the peak to fall outside the specific range offered, likely due to Wellington’s typical mid-July climate, which averages 8–12°C with frequent cloud cover and rain.

Historically, Wellington rarely exceeds 15°C in July; the last day above 18°C in mid-July occurred in 2019, and temperatures above 20°C are exceptional, usually tied to rare southeasterly ridging events. Given the settlement window ends at 12:00 UTC on 20 July 2026—just two minutes before the current time—the outcome is effectively determined, and the 0% probability aligns with the near-certain expectation that the recorded maximum will not reach the threshold implied by the YES side.

Traders should monitor Wunderground’s real-time update for NZWN, which will publish the final daily maximum shortly after midnight local time. No further catalysts exist, as the observation period has closed; the only dependency is the official data release from the resolution source. With the settlement moment imminent and historical patterns strongly favouring cooler conditions, the market reflects a high-confidence assessment of typical winter weather in the capital.

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

How fast do sports winnings settle?

Can I import form data and lineups?
