Madrid is bracing for a weekend surge in temperatures, with the State Meteorological Agency (AEMET) issuing a yellow alert for high temperatures on Saturday. After a brief respite, the region is set for some of its hottest days so far this summer. Maximums are expected to reach 37°C, and could hit 38°C in southern areas such as Aranjuez. The warning covers the central hours of Saturday, when the risk of heat-related incidents is highest. AEMET operates Meteoalerta, Spain’s national system for forecasting and monitoring adverse weather. The plan provides detailed warnings up to 72 hours ahead and tracks conditions as an event develops.
Forecasts show highs around 34°C in the Sierra, while much of the rest of the region will hover between 36°C and 37°C. In Aranjuez and other southern municipalities, the mercury could climb to 38°C. Although the alert does not extend to Sunday, elevated temperatures are expected to persist, putting continued pressure on local residents and services. Forecasts and measured temperatures are separate products: AEMET’s station service publishes hourly observations for the previous 24 hours and daily summaries for the preceding seven days. Its Puerto de Navacerrada record provides a reference for higher-elevation conditions, which can differ substantially from temperatures in the southern lowlands.
Saturday is forecast to bring mostly clear or slightly cloudy skies, with some high-altitude clouds possible. Minimum temperatures in Madrid city are expected to range from 16°C to 22°C, a slight rise from previous days. Winds will be light and variable at the start and end of the day, shifting to a moderate southwesterly in the Sierra during the afternoon.
On Sunday, conditions will remain stable, with little change in temperature or sky cover. Highs will again exceed 34°C in the lower Sierra and could reach 38°C in Aranjuez. Winds are expected to be light and variable overnight and in the evening, turning southwesterly during the morning hours.
Heatwaves and extreme weather have become a recurring challenge for Spain in recent years, often straining emergency services and prompting health advisories. The current alert in Madrid follows a pattern across the country, where authorities are increasingly vigilant about the risks of prolonged high temperatures. Severe weather has also affected other parts of Spain. A major wildfire in Guadalajara forced hundreds to evacuate amid intense heat and wind.
Spain’s approach to managing heat risks includes public information campaigns and temporary cooling centers, alongside targeted alerts for vulnerable populations. The yellow alert in Madrid is a reminder to take precautions during extreme weather, especially for people with health conditions, including the elderly and children. Residents are advised to stay hydrated and avoid outdoor activity during peak heat, while monitoring updates from AEMET and local authorities. As climate patterns shift, these episodes are likely to remain a basic concern for city officials and the wider public.
