According to meteorologists tracking the system, this weekend marks a decisive turning point as extreme thermal values retreat toward seasonal averages, making way for an approaching upper-level trough laden with widespread rain and thunderstorms across northern regions.
Saying Goodbye to Brutal Temperatures and the Guadalquivir Valley Furnace
For days, residents across southern Spain and inland valleys endured punishing conditions, with the Guadalquivir Valley routinely punching past the 40 ºC mark. Sunday morning breaks with low clouds and coastal mists shrouding Galicia, the Cantabrian coast, the Alboran Sea, and the Balearic Islands, offering an immediate visual cue that the atmospheric lid is lifting. While the southern half, the northeast, interior Mallorca, and the Canary Islands will still log maximums exceeding 35 ºC, the blanket of relentless heat is fracturing.
Nighttime conditions are also beginning to transform. Tropical nights—where temperatures refuse to drop below 20 ºC—remain entrenched across the Canary Islands, broad stretches of the southern mainland, the Ebro Valley, and the Mediterranean coast. However, daytime airmasses are cooling across the Atlantic slope, bringing welcome relief to regions that bore the brunt of the week’s thermal peak.
The Atlantic Front and the Onset of Northern Storms
The weather pattern evolution accelerates by Sunday afternoon as cloud cover thickens over mountainous regions in the eastern third and extreme northern territories. Isolated downpours are slated to strike the Cantabrian Mountains, the Pyrenees, and the Iberian System. Simultaneously, a frontal system approaches Galicia, introducing the first meaningful precipitation of the cycle.
Meanwhile, the Canary Islands experience their own micro-climate friction. Low clouds threaten mountain zones with damp weather, while a stubborn layer of calima haze lingers over southeastern districts and the islands, creating hazy skies and strained air quality for outdoor workers and tourists alike.
A Deepening Trough Ignites Severe Weather on Monday and Tuesday
This dynamic feature destabilizes the atmosphere, touching off intense thunderstorms across Galicia, Asturias, Cantabria, and the northwest of Castile and León. By nightfall, these cells march eastward toward Aragon.
By Tuesday, the focus of stormy activity shifts squarely onto the Pyrenees, the Cantabrian Cordillera, and the southern Iberian range. Mountainous pockets throughout the central and eastern peninsula face isolated but potentially sharp convective outbreaks.
Regional Breakdown: Sun, Mist, and Rising Storm Risks
Across the autonomous communities, the forecast reflects a patchwork transition from coastal mist to inland heat and eventual mountain storms:
- Galicia: Morning mists give way to mixed clouds and incoming precipitation along the coast, with maximum temperatures dipping notably.
- Asturias and Cantabria: High-altitude morning fog clears into developing clouds over the mountain ranges, with scattered light showers expected.
- Basque Country and La Rioja: Skies remain partly cloudy with high intervals, while maximum temperatures climb toward the mid-30s before the atmospheric shift takes hold.
- Aragon and Catalonia: Clear skies during the early hours will rapidly yield to heavy, storm-accompanied downpours, particularly near high terrain and the Ampurdán region.
- Madrid and Castilla-La Mancha: Mostly clear conditions persist initially, though maximums will still test thresholds, touching 36 ºC in the capital region and up to 39 ºC in specific southeastern corridors like Campo de Hellín.
- Andalusia and Extremadura: Temperatures drop noticeably across the Atlantic slope, though western winds bring strong gusts and occasional roughness to the Strait of Gibraltar and the Mediterranean littoral.
- Canary Islands: High temperatures dominate the lower elevations, peaking above 39 ºC on southern and western slopes of Gran Canaria, accompanied by strong wind gusts and localized minimums staying stubbornly above 28 ºC.
