**Stable high-pressure conditions and clear skies are positioning Madrid’s overnight low on September 13 near 15–17 °C, supporting the market’s heaviest volume on 15 °C or below (54 % implied probability).** Official forecasts from multiple models show radiative cooling under dry, calm nights with minimal cloud cover, producing minimum temperatures in that range after daytime highs reach 30–33 °C. Historical September climatology for central Spain places typical overnight lows around 15–18 °C, and current guidance aligns closely without indications of stronger advection or moisture that would raise minima. Updated model runs through early September 12 reinforce this consensus, with limited spread among ensembles. The next key update will come from overnight observations and morning verification data that directly determine the recorded daily minimum.

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.
