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 25 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 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 forecasts from multiple numerical weather models converge on a daytime high of 27–28 °C in Madrid on August 25, driven by moderate southwest flow, increasing afternoon cloud cover, and the absence of strong high-pressure ridging that produced hotter conditions earlier in August. This places the market’s heaviest volume on 28 °C (47 %) and 29 °C (36.5 %), with 27 °C a distant third, reflecting both the central tendency of ensemble guidance and residual uncertainty in boundary-layer mixing and exact cloud timing. The cooling trend relative to mid-August climatology (typical highs near 31 °C) has been evident in successive model runs over the past 48 hours and is expected to hold through the final verification period.
