Recent forecasts indicate a cooler air mass advecting into central Spain, driving the tight clustering of market-implied probabilities around 17–19°C minima for Madrid on August 27. Model consensus from sources such as the Met Office and BBC points to overnight lows near 12–13°C under partly cloudy skies with light winds and possible early sprinkles, though ensemble spreads reflect uncertainty in exact cloud cover and boundary-layer mixing that modulates radiative cooling rates. Climatologically, late-August Madrid lows average 16–17°C, so this setup represents a modest negative anomaly; traders weigh these dynamics against urban heat-island effects and resolution based on official station readings, with fresh model runs expected to refine the range before market close.

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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.
