Highest temperature in Madrid on August 7?

Platform comparison

Market context

Madrid is set up for another very hot August afternoon, with private and mainstream forecasts clustering around a high in the mid-to-upper 30s Celsius and some models nudging close to 38°C for the city on 7 August.[3][4][5][14] That matters for this market because the settlement source is the Airport Station’s *Daily Observations* table, not the summary tile, so the relevant number is the observed peak at Adolfo Suárez Madrid-Barajas rather than any headline forecast or citywide estimate.[2]

The 0% crowd price leaves little room for an upside surprise, but Madrid’s recent warm-season history shows that very high readings are plausible when a heat pattern locks in. Reuters reported Spain’s first official heatwave of 2026 pushed Madrid to 40°C in June, while climate records for Madrid include summer maxima above 40°C at other stations, underlining that the city can overshoot average August norms when hot continental air dominates.[15][17] By comparison, long-run August averages are far lower, around the low 30s Celsius for daytime highs, so a settled day in the high 30s still sits in a broadly familiar hot-season band rather than an exceptional outlier.[1][11][12]

The main catalysts are the day’s actual airport observations, not new team-news style inputs, and the key dependency is whether the peak is logged before the 12:00 UTC settlement cut-off and whether the station records materially differ from nearby city forecasts.[2] Traders should watch the hourly Met Office-style trace and any late-morning AEMET updates, because a final push in the early afternoon could shift the reading into a higher bracket if the local heat intensifies as forecast.[9][14]

FAQ

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.

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.

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.
