Ensemble forecasts from leading numerical weather prediction models like ECMWF and GFS drive trader sentiment toward mild highs of 15-18°C in Madrid on March 26, with implied probabilities clustering tightly around these outcomes at 17-26%. Current synoptic patterns feature a weak Atlantic ridge allowing variable cloud cover and light southerly winds, tempering diurnal heating while urban heat island effects add 1-2°C locally. Model spread of ±2-3°C reflects uncertainty from potential cold front timing, differentiating lower odds for 15°C or below (26%) from 19-21°C (15-17%), against March climatology averaging 16-17°C highs; extremes like 25°C+ (11%) remain unlikely without föhn-like downslope flow. AEMET updates tomorrow could shift odds further.

The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Adolfo Suárez Madrid-Barajas Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/es/madrid/LEMD.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market can not resolve to "Yes" until all data for this date has been finalized.
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.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
