Pronóstico: Highest temperature in London on July 17?

Platform comparison

Market context

London City Airport is currently recording 13°C with southerly winds and high humidity, a stark contrast to the scorching conditions required for a positive outcome in this weather prediction market. The settlement window closes at noon UTC on 17 July 2026, meaning the market will resolve based on the peak temperature reached before that deadline. With the crowd-implied probability for a "YES" result sitting at 0%, traders are effectively betting that temperatures will fail to breach the threshold defined for a winning outcome, likely due to the prevailing cool and damp atmospheric conditions observed this morning.

Historical data for mid-July in London typically sees highs between 20°C and 25°C, yet extreme heatwaves can push readings above 30°C, as seen during the 2022 heat event. However, the current 0% probability suggests the market perceives the specific range required for a "YES" as virtually unattainable under the forecast, possibly because the threshold is set significantly higher than typical July averages or because the immediate forecast predicts a continued cool spell. Comparable cases from recent years show that while London experiences warm days, the specific combination of high humidity and falling pressure observed today often suppresses peak temperatures, making extreme highs less likely.

Traders should monitor real-time updates from Wunderground and BBC Weather for any sudden shifts in the forecast, particularly changes in wind direction or cloud cover that could alter the day’s peak temperature. A key catalyst is the 12:00 UTC settlement deadline; any temperature spike occurring after this time will not count. Additionally, watch for official meteorological announcements regarding heat advisories, as these could signal a rapid change in conditions. Given the current 13°C reading and falling pressure, the immediate outlook suggests temperatures will remain well below the levels needed to trigger a positive resolution, reinforcing the market’s current stance.

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.

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.

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.

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.
