Recent forecasts from multiple models point to a high in Madrid on September 18 in the mid-to-upper 20s °C under clear skies and light northeasterly winds, consistent with a cooling trend after early-September warmth exceeding 34 °C. Trader positioning remains diffuse because small differences in peak afternoon heating, boundary-layer mixing, or slight model disagreements on wind speed can shift the daily maximum across the 27–30 °C range. Historical climatology shows late-September averages near 26 °C, but persistent high pressure and minimal cloud cover support the modest premium on 32 °C or higher. Updated runs from the European and global ensembles over the next 48 hours will likely narrow the spread ahead of resolution.

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.
