Current forecasts from agencies and models indicate a daily maximum in Madrid near the September climatological average of 26.2°C, driven by stable high pressure, light northeasterly winds, and partly cloudy skies that limit extreme solar heating. Real-time observations on September 17 show temperatures climbing through the mid-20s under dry conditions with low precipitation probability. This positioning supports the market's strong weighting toward 26–27°C outcomes, as deviations would require unexpected shifts in cloud cover or wind patterns. Upcoming afternoon readings and official AEMET verification will determine final resolution.

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 17 Sep '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.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.Current forecasts from agencies and models indicate a daily maximum in Madrid near the September climatological average of 26.2°C, driven by stable high pressure, light northeasterly winds, and partly cloudy skies that limit extreme solar heating.
