Market context
The highest temperature recorded at Minister Pistarini International Airport in Buenos Aires on 18 July 2026 will determine this market's resolution. July falls within Buenos Aires' winter season in the Southern Hemisphere, when daytime highs typically range between 13–16°C, though occasional warm fronts can push readings into the low 20s. The airport station, located in Ezeiza roughly 35 kilometres south-west of the city centre, sits on the Río de la Plata's western bank and experiences slightly cooler conditions than central Buenos Aires due to its proximity to water and lower urban heat island effect.
Historical July data from the same station shows maximum temperatures rarely exceed 22°C during the month, with most days settling in the 12–17°C band. Extreme outliers—readings above 25°C in July—occur roughly once per decade when subtropical air masses push southward, displacing the typical cold fronts that dominate winter. The 0% crowd probability suggests traders expect a standard winter day rather than an anomalous warm event.
Traders should monitor long-range forecasts from Argentina's Servicio Meteorológico Nacional from mid-July onwards, as these will clarify whether high-pressure systems or warm northerly flows develop. Southern Hemisphere winter patterns typically stabilise by late June, making dramatic departures from seasonal norms increasingly unlikely as July progresses. Real-time Wunderground data will be the sole settlement source, requiring verification of the specific airport station's readings rather than central city observations.

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?
- 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.
