Forecast models from agencies like the European Centre for Medium-Range Weather Forecasts show Madrid under a persistent high-pressure ridge with light winds and clear skies through mid-August, supporting daily maxima near 34–36 °C on the 15th. Ensemble spreads remain wide because small shifts in the position of an approaching Atlantic trough or local boundary-layer mixing can add or subtract 2–3 °C. Historical August climatology places the long-term average high at 33 °C, so current guidance sits slightly above normal yet within the typical interannual range. Traders therefore price the 32–38 °C outcomes near even money while assigning minimal probability to 39 °C-plus readings, reflecting both the consensus forecast envelope and the limited time remaining for major pattern changes before resolution.
