AEMET, Spain’s national meteorological agency, issued its first special heatwave advisory of the year on 20 June 2026, warning that from Sunday 21 June highs could reach 44 °C in the Guadalquivir and Ebro valleys, interior Catalonia and parts of Extremadura. Some airports—Seville, Córdoba and Zaragoza—have already placed apron-work restrictions after 13:00 to protect ground staff, potentially lengthening turnaround times for domestic and Schengen flights. Rail operator Renfe indicated that high-speed AVE services may impose temporary speed reductions on exposed stretches, adding up to 15 minutes to Barcelona-Madrid journeys. Car-rental firms are bracing for last-minute cancellations as regional authorities consider limiting private vehicle access to natural parks with extreme fire risk. From a duty-of-care standpoint, companies should update travel policies to include mandatory hydration breaks for mobile employees and encourage use of municipal “refugios climáticos” (air-conditioned public buildings) during daytime appointments. The heatwave coincides with record tourist arrivals and with large-scale rail engineering works on the Valencia-Gandia line, raising the likelihood of missed connections. Health insurers that underwrite expatriate and digital-nomad policies point out that power prices generally spike during Spanish heatwaves, so serviced-apartment contracts with utilities included may offer better cost predictability for short-term assignees.
