Seville starts summer under heat alerts as Spain’s first heat wave builds

Seville entered the astronomical summer on Sunday under heat warnings as Spain’s first major hot spell of the season began to intensify across Andalusia.

AEMET alerts were in place for several provinces, including Almería, Córdoba, Jaén, Granada and Seville. Córdoba and Jaén were at orange level, while the Sevillian countryside and the Capital and Montes area of Jaén were under yellow warning between 1 p.m. and 9 p.m.

A heat episode building across Andalusia

Forecasts pointed to highs of around 39C to 40C in the warned areas, with temperatures expected to climb above 40C by midweek. That is when the episode is expected to deepen into what meteorologists describe as the first heat wave of the summer.

The local reporting that prompted the alert package said Seville was starting summer with heat warnings already in force, rather than waiting for the season to settle in.

Health protocol remains active

The Andalusian regional government keeps its protocol for reducing the health impact of excessive temperatures active until September 30. The plan is designed to coordinate prevention and response during summer heat episodes.

Regional minister Antonio Sanz said the device is meant to reduce the impact of heat and protect the most vulnerable groups, especially older adults, children and people with chronic illnesses.

What to watch next

The next key check is whether AEMET expands or raises warnings in Seville and other Andalusian provinces as the week progresses. Officials are also watching for further health guidance or support measures from the Junta de Andalucía if the forecast heat becomes more severe.

For now, the confirmed picture is clear: summer has begun in southern Spain with warnings already in place, and the first significant heat event of the season is only expected to strengthen.
