Summer Heat and Calima Alert for Spain in April

by Chief Editor

Spain has experienced a weekend of clear skies and favorable weather, with temperatures mirroring those typically seen in the summer. This warming trend is expected to persist through the beginning of the coming week.

Extreme Warmth and Historical Records

The State Meteorological Agency (AEMET) has warned that the air masses currently situated over Spain are “extremely warm.” This atmospheric condition may lead to temperatures that exceed the highest values recorded between 1991 and 2020 for this time of year.

According to AEMET, this represents another “episode with summer heat in April,” following a similar occurrence in 2023.

Did You Know? This current weather pattern is being compared to a previous “summer heat in April” episode that took place in 2023.

Monday: Calima and Regional Heat Peaks

The start of the week will be characterized by the arrival of calima across the Peninsula. This dust haze is expected to advance from the west while receding in the Canary Islands.

Maximum temperatures could reach 30 degrees in several cities, including Madrid, Toledo, Murcia, Albacete, Córdoba, Jaén, Guadalajara, Huelva, Logroño and Zaragoza. Across most of the territory, values are likely to remain above 20 degrees, with minimums generally staying above 10 degrees.

Regional Instability and Storms

While many areas face high heat, instability may affect the Ebro Valley, Navarra, the Iberian System, and the Pyrenees. This could result in hail and storms, with the possibility of strong showers in the eastern Pyrenees.

In contrast to the 30-degree peaks, AEMET predicts a drop in maximum temperatures along the Galician coast and in the Ampurdán region.

Expert Insight: The coexistence of subtropical heat and regional instability suggests a highly volatile atmospheric transition. The entry of calima combined with extreme warmth creates a complex weather scenario where summer-like peaks and severe spring storms occur simultaneously across different zones of the Peninsula.

Tuesday Outlook: Wind and Subtropical Air

Storms may continue into Tuesday, potentially accompanied by extremely strong wind gusts in the Pyrenees, the Cantabrian Range, Galicia, and various interior points.

AEMET indicates that the formation of a low-pressure system to the west of the Peninsula may facilitate the entry of a warm air mass of subtropical origin. Calima could continue to enter the Peninsula from the south.

Temperatures are expected to follow a similar pattern to Monday, with potential peaks of 30 degrees in cities such as Palencia, and Murcia.
