Recent official forecasts from AEMET and supporting ECMWF/GFS model consensus point to a peak of 33–34°C in Madrid on August 31 under clear skies, high pressure, and light winds that favor strong daytime heating without significant mixing or cloud cover. This setup aligns with the market’s heavy weighting toward 34°C (52.5%) and 35°C (26.0%), as current runs show afternoon maxima near or slightly above the 32–33°C climatological norm for late August while ruling out cooler outcomes. Low humidity and minimal precipitation risk further support these levels, though any late-model shift in steering flow or added moisture could trim the high end before resolution.

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.
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.
