Latest ECMWF and AEMET ensemble forecasts drive trader consensus toward a Madrid high temperature of 18-20°C on March 27, with model means clustering near 19°C amid a high-pressure ridge promoting mild, sunny conditions and southerly flows advecting warmer air from the Mediterranean. Historical March maxima at Barajas Airport average 17°C but vary ±3°C due to diurnal cycles and urban heat islands, explaining the tight odds spread; recent GFS updates nudged probabilities upward from cooler 17°C outlooks by reducing cloud cover risks. Low precipitation odds (under 10%) minimize cooling effects, though minor ensemble divergences on peak-hour insolation differentiate 18°C (shaded biases) from 20°C (clear-sky peaks). Traders eye tomorrow's 12Z model runs for resolution shifts.

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.
