Spain Portugal Weather Heatwave – Maps, Records and 2025 Updates

The Iberian Peninsula has experienced a series of extreme heatwaves in recent years, with 2025 emerging as the most severe season on record. Spain and Portugal have shattered temperature records, with the mercury climbing past 46°C in multiple locations during the summer months. These events have prompted emergency responses, renewed climate debates, and increased public attention on heat safety across southwestern Europe.

Authorities including Spain’s AEMET and Portugal’s IPMA have documented the progression of these heat events, linking them to broader patterns of rising global temperatures. The summer of 2025 brought multiple consecutive heatwaves, with peak temperatures exceeding 44°C across large swaths of both countries. Climate scientists have pointed to these events as evidence of the intensifying impact of global warming on Mediterranean regions.

For travelers and residents alike, understanding the scope and timing of these heatwaves has become essential for planning. Interactive mapping tools and data from monitoring agencies now provide detailed views of temperature anomalies across the peninsula, offering insights into both past events and ongoing conditions.

Heatwave Snapshot Facts

Spain Portugal Weather Heatwave 2023

The April 2023 heatwave that struck Spain, Portugal, Morocco, and Algeria represented a landmark event in Mediterranean climate history. A comprehensive study published by MedECC concluded that this extreme heat event was made 100 times more likely due to human-induced climate change. The research marked one of the earliest formal climate attribution analyses for the region.

2022 Heatwave Context

Preceding the 2023 event, the summer of 2022 brought severe heatwaves that pushed temperatures above 45°C across both Spain and Portugal. Excess mortality data mapped by the European Environment Agency documented the human cost of these extremes, with the Iberian Peninsula experiencing significant death tolls attributed to heat stress. That year’s events established a new benchmark for European heat, with the United Kingdom recording its first 40°C temperature of 40.2°C.

Long-Term Pattern Recognition

The sequence of extreme heat events from 2022 through 2025 demonstrates an escalating pattern of temperature records being broken with increasing frequency. While the 2023 event was notable for its unusual timing in April, the subsequent years have shown summer peaks climbing ever higher. August 2023 ranked among the two warmest months on record globally, a distinction shared with August 2024, underscoring the broader trend of accelerating heat extremes.

Highest Temperature in Spain 2025

Spain’s temperature records for 2025 reflect unprecedented heat intensity across the country. The most significant reading came from El Granado in the province of Huelva, where 46°C was recorded during the intense early-season heatwave. This surpassed earlier May readings of 39.1°C at the same location and established a new benchmark for the country’s 2025 thermal extremes.

Spain’s AEMET weather service confirmed temperatures exceeding 44°C on 16 August 2025, during the third major heatwave of the summer. The June-through-August period delivered Spain’s hottest summer on record, with an average temperature of 24.2°C across the mainland and islands. Early warnings issued for Andalusia and Catalonia in May had already signaled the severity of the developing conditions.

These extreme readings align with broader European patterns documented during the August 2025 southwestern Europe heatwave. Maximum temperatures of 40°C to 45°C were recorded across the Iberian Peninsula, with feels-like temperatures reaching into the mid-40s in southern Spain and Portugal. The concentration of extreme heat events throughout the 2025 calendar year underscores a pattern of prolonged and intensified thermal stress.

Portugal Heatwave

Portugal’s IPMA meteorological institute documented multiple heatwave events throughout 2025, culminating in a record-breaking June that saw the nation’s all-time high for that month set in Mora at 46.6°C. This temperature marked a significant departure from historical norms and represented the most extreme reading recorded in Portugal during the year.

May 2025 Records

May 2025 brought preliminary extreme heat to Portugal before the summer season officially began. On 28 May, Beja recorded 37.4°C, followed two days later by Amareleja reaching 39.8°C on 30 May. These early-season readings provided an ominous indicator of the heat intensity that would characterize the remainder of the year. The rapid progression from spring warmth to extreme heat illustrated the accelerated thermal buildup characteristic of 2025 conditions.

Late-Year Conditions

Available records show no November-specific highest temperature data for Portugal or Spain in the research examined. Heatwave activity during the final months of the year remains outside the documented patterns, with all major extreme temperature events concentrated in the spring and summer periods. This seasonal limitation means November queries regarding Iberian heatwaves typically relate to travel planning for the following year or reflections on the preceding summer’s conditions.

Spain Portugal Heatwave Timeline

Understanding the chronological progression of heat events helps contextualize the escalating nature of Iberian heatwaves. The following timeline documents key moments from 2022 through 2025, drawing from official weather services and climate monitoring agencies.

1. July 2022: Early heatwave queries emerge as temperatures exceed 45°C across Spain and Portugal, marking one of the first summers where 45-degree thresholds became regularly discussed
2. April 2023: Extreme event strikes Spain, Portugal, Morocco, and Algeria; MedECC study attributes the event as 100x more likely due to climate change
3. May 2025: Late spring heatwave forecast arrives early, with Portugal’s Beja reaching 37.4°C on 28 May and Amareleja hitting 39.8°C on 30 May
4. June 2025: National records shattered as Portugal’s Mora records 46.6°C and Spain’s El Granado reaches 46°C
5. August 2025: Southwestern Europe heatwave (8-18 August) brings 40-45°C maximums; AEMET confirms 44°C+ on 16 August; August ranks as third warmest on record globally

The progression from 2022 through 2025 illustrates not only increasing frequency but also escalating intensity, with each successive year bringing new temperature records that push the boundaries of what was previously considered extreme for the region.

Heatwave Forecasts: Facts vs Projections

Distinguishing between verified temperature records and model-based projections remains essential for accurate reporting on heatwave conditions. The following comparison clarifies what is established fact versus ongoing uncertainty in the current data.

Analysis: Why These Heatwaves Matter

The recurrence of extreme heat events across Spain and Portugal carries implications extending far beyond temperature records. Public health systems face mounting pressure during peak summer months, with excess mortality data demonstrating the direct human cost of heat exposure. The European Environment Agency’s mapping of deaths during the 2022 heatwaves revealed thousands of preventable fatalities correlated with temperature extremes.

The tourism and agriculture sectors must increasingly factor heat risk into seasonal planning. For travelers, understanding when extreme conditions are most likely supports better decision-making around travel dates and activity scheduling. Agricultural operations face crop risks and water scarcity challenges intensified by repeated heat exposure.

Climate science continues to strengthen the connection between these events and broader warming trends. The MedECC attribution study demonstrating the 100-fold increase in likelihood for the April 2023 event provides a scientific framework for understanding these extremes as indicators of systemic change rather than isolated anomalies.
