Recent numerical weather prediction consensus from models such as GFS positions Madrid’s August 31 high near 34°C, driven by persistent high pressure, clear skies, and light southerly flow that enhances daytime solar heating under low humidity. Late-summer continental conditions typically support maxima of 30–32°C, yet the current subsidence and minimal cloud cover favor readings at or slightly above that baseline. Updated short-range forecasts show little model spread for the period, with negligible precipitation risk and stable steering patterns limiting cooler advection. Official AEMET observations at 2-meter height will determine resolution, with traders assigning the highest implied probability to 34°C given this stable, warm setup.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Adolfo Suárez Madrid-Barajas Airport Station in degrees Celsius on 31 Aug '26.
The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=lemd
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °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.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.Recent numerical weather prediction consensus from models such as GFS positions Madrid’s August 31 high near 34°C, driven by persistent high pressure, clear skies, and light southerly flow that enhances daytime solar heating under low humidity.
