Recent short-range forecasts from agencies like AEMET and the Met Office indicate Madrid highs near 35°C on August 5 amid post-heatwave moderation after Spain’s intense July conditions. Ensemble model spreads from ECMWF highlight uncertainty in peak daytime heating driven by subtle variations in surface pressure gradients, northerly wind advection, and urban heat island effects, which explain why traders assign roughly equal weight to 35°C and 36°C outcomes. Historical August baselines near 33°C and ongoing dry soils that enhance sensible heat flux further support the tight clustering around these values while limiting upside risk for 37°C or higher. Updated model runs in the next 48 hours will likely refine the market-implied odds.
