Euskadi logs its first four straight days under red heat alert

The Basque Country is on track to complete an unprecedented four straight days under AEMET’s maximum red heat alert, with authorities warning that the situation could still worsen.

The alert is centered on the interior of Bizkaia and Gipuzkoa, where temperatures have been exceeding 40C in parts of the territory. Cadena SER reported that this would be the first time Euskadi has logged four consecutive days under a red heat warning since the current AEMET alert system began in 2007.

A rare run of red alerts

According to the reporting, the red alert has run from Sunday through Wednesday. AEMET delegate Enric Armengol said there was no previous precedent in Euskadi for this sequence of maximum-level warnings.

The episode is notable not only for the temperature peaks, but for its duration. Officials have warned repeatedly that prolonged extreme heat raises health risks, especially when nights stay hot and people do not get enough recovery time between days.

The wider weather pattern is part of a broader early-summer heatwave across Spain. El País reported that the country was facing widespread heat conditions, with Euskadi under red alert and temperatures around 42C in other regions.

Public services are already changing

The heat has already started to affect everyday services. The Basque public childcare network Haurreskolak moved its closing time up to 13:00 while the alert remains in force, according to Cadena SER.

That change shows how the alert is cascading into family routines and municipal operations. Schools, childcare centers and outdoor activities are among the first services to adjust when extreme heat persists for several days in a row.

The Basque Labor Inspection also notified 3,063 companies about their obligations to protect workers from heat exposure. That warning is especially relevant for outdoor jobs, where exposure can become dangerous quickly during a sustained heat episode.

Officials are still monitoring the situation

Basque emergency chief Joseba Zorrilla said authorities were continuously monitoring conditions and did not rule out additional restrictions if the weather worsens. The emergency response also said it was evaluating whether to limit or relocate San Juan bonfire-related activities and other outdoor events, especially those involving children.

That leaves organizers of public celebrations and festivals in a state of uncertainty as the alert continues. The possibility of new limits is part of the broader public-safety response now unfolding around the heatwave.

Officials have also emphasized the health risks for older adults, children, pregnant people, people with chronic illness and outdoor workers. The danger is greatest when high daytime temperatures are paired with hot nights, which can make consecutive heat days more dangerous than a single peak.

What comes next

The main question now is whether the red alert will continue beyond Wednesday and whether the Basque Government adds new restrictions. Authorities are also watching for any official temperature records or fresh updates from AEMET and regional emergency services.

For now, Euskadi’s first four-day red-alert run has become a public-health, workplace and event-planning issue at the same time. The developing story now depends on whether the heat breaks or whether officials are forced to tighten measures further.
