Highest temperature in Wellington on July 31?

Platform comparison

Market context

Wellington’s 31 July temperature is shaping up as a cool, damp winter reading rather than a warm outlier, with forecasts pointing to a high of about 12°C and patchy rain nearby at Wellington Airport. That sits close to the city’s late-July norms, where average daytime highs are around 11–12°C and July is typically wet and breezy rather than mild or settled.[1][11][19]

That context helps explain why the market’s 0% YES price is not really about heat, but about whether the airport can deliver a genuinely exceptional daily maximum. Historical July data for Wellington shows highs usually in the low teens, with daily highs rarely pushing beyond the mid-to-high teens, so a higher temperature band would require a clear deviation from seasonal pattern. Forecast services are already clustering around a low-teens outcome, which makes the upper temperature ranges less plausible unless the forecast shifts materially overnight.[2][7][11]

The main catalysts are straightforward: a late change in the Wellington Airport forecast, especially cloud break-up, wind easing, or a warmer northerly flow, could lift the day’s maximum; conversely, rain and stronger southerlies would cap upside. AccuWeather has also highlighted a Strong Winds Watch for Wellington running into Friday morning, with northerly winds potentially approaching severe gale in exposed places, while local sources describe windy, showery conditions easing later.[4][6][13] For traders, the key dependency is whether the airport records an early warm spike before cloud and rain dominate the rest of the day.[3][14]

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.

Which sports markets are available?

How fast do sports winnings settle?

What's the difference between match odds and outright odds?

Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.
