Market context
Wellington's maximum temperature on 14 July 2026 will be measured at the International Airport weather station, with settlement determined by historical records from Wunderground. July falls within Wellington's winter season in the Southern Hemisphere, when daytime highs typically range between 8–13°C, though the city's exposed coastal location and variable weather patterns mean conditions can shift considerably within a single day.
Historical July records for Wellington show maximum temperatures rarely exceed 15°C, with the airport station recording extremes between 5°C and 18°C across the past three decades. Cold fronts moving across the Cook Strait can suppress temperatures into single figures, whilst sheltered northerly flow occasionally pushes readings toward the upper teens. The 0% crowd probability suggests traders expect a relatively cool day, consistent with mid-winter norms for the region. Comparable July dates from recent years provide the most reliable baseline: the airport's records indicate roughly 60% of July days peak below 11°C, with only occasional outliers above 14°C driven by unusual high-pressure systems.
Traders should monitor MetService forecasts released in the week preceding 14 July, as these will clarify whether high-pressure systems or frontal activity dominates the forecast period. The settlement window closes at midday UTC (midnight Wellington time), meaning the final temperature reading will capture the full daylight heating window. Any significant departure from typical winter patterns—such as an early spring warm spell or an unusually deep low-pressure system—would shift probability distributions materially, though such events remain statistically uncommon for mid-July in Wellington.

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.
- 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.
- 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.
