Highest temperature in Wellington on July 31?

Platform comparison

Market context

Wellington’s reading on 31 July will come down to whether the airport gets a brief, warmer spell in the middle of a generally cool, windy winter day. Current forecasts point to patchy rain nearby with a high of about 12–13°C, while the BBC observation at Wellington/Intl is already around 10°C with light northerly winds and high humidity, which is consistent with the city’s usual winter range rather than an outlier heat event.[1][3]

That makes the market’s 0% implied probability look more like a reflection of a very subdued ceiling than a hard impossibility: Wellington’s July highs typically sit near 11–12°C, and climatology puts daily highs around 53°F, or roughly 12°C, with only modest day-to-day variation.[11][17] The seasonal outlook from NIWA also leans near average to below average temperatures across the country, with cold snaps still possible later in winter, which supports a low-end distribution rather than a spike towards unusually warm readings.[19]

For traders, the key catalysts are the final overnight and morning forecast updates, especially any shift in wind direction, cloud break, or rain timing before the settlement window closes at 12:00 UTC. Strong wind watches are already in place for Wellington, with northerly winds expected to ease through Friday morning, and the airport maximum can be sensitive to brief clears or downslope warming if showers arrive later than forecast.[4][7]

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.

When do sports markets resolve?

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

Can I bet on individual matches?

Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.

How fast do sports winnings settle?

Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
