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.
Clear skies and light southerly winds under high pressure are positioning Madrid for a daily maximum near 33–34°C on August 31, aligning with the dominant market-implied probabilities. Official AEMET guidance and ensemble forecasts emphasize strong daytime insolation with minimal cloud cover and dew points around 10–12°C, supporting efficient surface heating in the city’s continental-Mediterranean setting. Recent model runs show tight consensus around these values, consistent with late-August climatology where highs average near 30–31°C but frequently reach the mid-30s under anticyclonic conditions. No significant advection of cooler air or convective development is expected today, keeping the distribution narrow; later updates from surface observations will determine whether the peak edges toward 35°C.
