**Clear skies under persistent high pressure are driving trader expectations for a notably cool overnight minimum in Madrid on September 11.** Recent GFS and other model runs indicate radiative cooling under dry, calm conditions will push the daily low into the low-to-mid teens °C, with several forecasts centering around 12–14 °C—well below the 16.2 °C climatological average for the date. This aligns with the market-implied 70 % probability on 11 °C or below, as the current synoptic pattern favors efficient nocturnal heat loss without cloud cover or significant wind to moderate temperatures. Warmer outcomes (21 °C+) remain possible only if models shift toward increased moisture or a stronger southerly flow, but consensus currently supports the cooler scenario ahead of the next major forecast updates.

The resolution source for this market will be information from NOAA, specifically the lowest 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.
