Madrid's peak temperature on August 9 is projected to reach 37°C under a strong high-pressure ridge promoting subsidence and clear skies, consistent with National Weather Service and European Centre for Medium-Range Weather Forecasts guidance. Recent model runs show minimal spread around this value, aligning with climatological August norms of 32–34°C highs while reflecting the current heat dome's intensification. Trader consensus at 100% for 37°C reflects real-time skin-in-the-game assessment of observational data and short-range forecasts. A sudden increase in boundary-layer moisture, unexpected convective development, or a sharper steering flow shift could alter the maximum by 1–2°C before evening observations finalize the market resolution.

This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the highest temperature recorded at the Adolfo Suárez Madrid-Barajas Airport Station in degrees Celsius on 9 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Adolfo Suárez Madrid-Barajas Airport Station, available here: https://www.wunderground.com/history/daily/es/madrid/LEMD.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
