Highest temperature in Wellington on July 20?

Platform comparison

Market context

Wellington is experiencing a cool, south-south-westerly flow on 20 July 2026, with current readings at Wellington International Airport showing 15°C, 72% humidity, and winds of 24 mph from the south-south-west [2]. This live data reflects the day’s conditions as the settlement window closes, yet the market currently assigns 0% probability to any outcome above the frontrunner range, which is 12°C at 100% probability [1]. The discrepancy between the observed 15°C and the market’s 12°C frontrunner suggests either a lag in resolution data ingestion or a misalignment between real-time weather and the Wunderground historical record that will determine settlement.

Historically, mid-July in Wellington typically sees maximum temperatures between 10°C and 14°C, with extremes rarely exceeding 16°C due to the city’s maritime climate and frequent southerly winds. The current 100% probability assigned to 12°C aligns with this long-term median, making the 0% probability for higher ranges consistent with seasonal norms rather than an anomaly [1]. Traders should monitor the official Wunderground daily history page for NZWN, as the market resolves solely on its recorded maximum for the day, not on live BBC or other third-party feeds [1]. Any delay in Wunderground updating the daily maximum could temporarily distort perceived probabilities before final settlement.

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.

What are live sports odds on Polymarket?

Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.

Which sports markets are available?

Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.

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.
