Highest temperature in Madrid on August 16?

Platform comparison

Market context

Madrid's weather on 16 August 2026 will be measured at Adolfo Suárez Madrid-Barajas Airport, with resolution determined by the Daily Observations table on Weather Underground rather than summary figures. The market currently shows 0% implied probability, suggesting traders expect temperatures to fall outside whatever range this particular option represents—likely an extreme threshold set well above typical August conditions in the Spanish capital.

August temperatures in Madrid historically peak between 35°C and 40°C, with daily highs regularly exceeding 38°C during mid-month heat waves. The city's continental climate and inland location produce consistent summer heat, though specific daily maxima vary considerably year to year. Weather Underground's station data from previous Augusts shows readings typically cluster in the 36–39°C band, with occasional spikes above 40°C during exceptional heat events. The 0% probability suggests this market option may be pitched at an outlier threshold—either an unusually low range or an extreme high that defies recent climatological patterns.

Traders monitoring this market should track European weather forecasting updates from mid-August 2025 onwards, particularly from ECMWF and Météo-France models that influence Spanish conditions. Any significant heat dome or Atlantic pressure system affecting the Iberian Peninsula in the weeks preceding 16 August could shift expectations materially. Airport station readings can differ from city-centre measurements due to elevation and local geography, so familiarity with Barajas's specific microclimate—situated on Madrid's eastern outskirts at approximately 600 metres elevation—matters for calibrating realistic temperature ranges against the current zero-probability assessment.

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.

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.

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.
