Trader consensus around 13–16°C for Madrid’s September 17 minimum reflects model agreement on moderate overnight radiative cooling under partly cloudy skies and light northeast winds. High pressure maintains dry, stable conditions with dew points near 5–8°C, limiting extreme drops while allowing temperatures to reach the mid-teens in urban stations before sunrise. Ensemble forecasts show limited spread due to consistent steering patterns and absence of frontal systems, keeping resolution sensitive to exact station readings and timing. Updated AEMET observations and next model runs will refine the final value within the narrow implied-probability band.

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.
