Latest numerical weather prediction models and AEMET guidance indicate clear to partly cloudy skies over Madrid on September 18 under a stable high-pressure regime, with light northeasterly flow limiting moisture and cloud cover. This setup supports efficient daytime heating on the meseta, positioning the maximum near 27–28 °C—values that align with the market’s leading implied probabilities. Ensemble consensus shows minimal spread, with only modest uncertainty from boundary-layer mixing and exact wind direction; historical September 18 averages hover around 26 °C, but recent dry, sunny conditions have pushed daily maxima 1–2 °C above normal. Final AEMET updates and the 00 UTC model runs tomorrow morning remain the key near-term catalysts that could refine these odds.

The resolution source for this market will be information from NOAA, specifically the highest 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.
