Recent meteorological model consensus from sources like the European Centre for Medium-Range Weather Forecasts indicates a daytime maximum in Madrid on May 18 near 23–24°C under stable high-pressure conditions with light southerly flow and minimal cloud cover. This setup limits significant warm advection or radiative heating spikes, aligning with climatological norms for mid-May when average highs hover around 22–24°C. Minor forecast revisions over the past 24 hours have reinforced this range, with ensemble spreads narrowing around these values and little evidence of outlier warming from upstream Atlantic patterns. Traders appear to weigh these stable atmospheric conditions heavily, as final official readings from the Spanish State Meteorological Agency will resolve the market based on precise maximum observations.
