Highest temperature in Madrid on August 16?

Platform comparison

Market context

Madrid's peak temperature on 16 August 2026 will be measured at Adolfo Suárez Madrid-Barajas Airport and recorded in Weather Underground's Daily Observations table. The settlement hinges on this specific data source rather than the Day High & Low summary, which occasionally diverges from granular station readings. Current crowd pricing sits at 0% YES across all temperature bands, suggesting either extreme confidence in a narrow range or insufficient liquidity to establish meaningful odds.

August temperatures in Madrid historically cluster between 32–38°C, with extremes occasionally breaching 40°C during heat waves. The 2022 European summer saw Madrid record 40.5°C on multiple days; the 2003 heat wave pushed readings to 40.8°C. These precedents frame the probability distribution—most outcomes fall within the 33–37°C band, whilst readings above 39°C remain plausible but less frequent. The 0% crowd probability suggests traders are either waiting for deposit settlement or treating this as a placeholder market pending deeper book formation.

Traders should monitor European weather forecasts from mid-August 2026, particularly Atlantic pressure systems and Saharan air mass movements that drive Madrid's summer extremes. The Spanish meteorological agency (AEMET) publishes detailed forecasts ten days ahead; significant deviations from seasonal norms typically emerge by early August. Liquidity on this market will likely depend on deposit rails—SEPA transfers and Klarna's payment infrastructure determine how quickly capital flows into the book once forecasts crystallise, directly affecting spread tightness and resolution certainty.
