Zaragoza is under a yellow alert for storms and rain this Sunday, issued by the Agencia Estatal de Meteorología (AEMET). The warning covers the Ribera del Ebro area, where conditions are expected to change quickly throughout the day. Skies will be mostly clear early in the morning, but cloud cover is forecast to increase from 06:00, bringing light drizzle that could intensify as the day progresses.
AEMET forecasts the heaviest rain and storm activity between late morning and 18:00. Initial precipitation around midday is expected to be minimal, barely 0.1 liters per square meter, but showers may grow heavier and more persistent later. Thunderstorms are probable during the morning and could return in the afternoon. Storms are expected to ease by early evening, though clouds will linger.
Temperatures in Zaragoza will also shift, with maximums dropping to around 35°C by 16:00, below recent highs. Minimum temperatures will remain above 22°C, while the lowest perceived temperature will be near 21°C. Light easterly breezes are forecast for Sunday.
On Monday, intervals of cloudiness are expected from the early hours until midday, followed by gradually clearing skies. Temperatures will change only slightly, with highs near 34°C and lows around 20°C. Winds will shift to a light northwesterly direction. Tuesday is forecast to be clear, with no precipitation; maximum temperatures will again exceed 34°C, while minimums will change only slightly. Light northwesterly breezes will continue.
This unsettled weather in Zaragoza comes amid changing summer conditions across Spain. The Madrid region recently experienced a sharp drop in daytime temperatures after a prolonged heatwave, as detailed in a recent report on the sudden cooldown in Madrid. Such swings make official weather updates especially impressive during periods of heightened alert.
AEMET’s Meteoalerta system is Spain’s official structure for forecasting and communicating hazardous weather, including rain and thunderstorms, as well as hail or strong winds. It provides detailed information up to 72 hours ahead and updates warnings as conditions evolve. A yellow alert signals a potentially hazardous situation that calls for caution; it does not automatically suspend public activity. Storm development can change warning areas and the timing or severity of conditions, so check the latest warning close to the event.
Forecasts for Zaragoza use time-specific probabilities and do not guarantee rain at every location. Conditions in the Ebro Valley can change quickly, and gusts may strengthen abruptly around storm cells even when the general wind forecast is light. Residents planning outdoor activities should consider rainfall intensity, while also watching for lightning and sudden gusts.
