The State Meteorological Agency (AEMET) has placed 27 Spanish provinces under orange or red alert as the second heatwave of summer 2026 sweeps the peninsula between Sunday 5 July and Tuesday 7 July. Forecasts suggest temperatures could hit 44 °C in the Guadalquivir and Guadiana valleys—levels that trigger mandatory contingency measures at airports, rail operators and motorway concessions. Euronews reports that railway company Renfe has activated “hot-weather protocols”, including speed restrictions on lines where rail buckling risks rise above 40 °C. Madrid-based infrastructure manager Adif has also adjusted catenary tension and scheduled additional patrols along the high-speed AVE corridor to Seville.

If the extreme temperatures force you to change travel dates or extend your stay, VisaHQ can simplify the paperwork by providing real-time entry requirements, online visa applications and expert support for Spain and other destinations. Visit to review your options and submit documents quickly—particularly useful when transport disruptions make last-minute itinerary shifts inevitable.
At airports, Aena has issued NOTAMs allowing carriers to request ground-handling delays of up to 30 minutes so that staff can take hydration breaks. Airlines including Iberia and Vueling are waiving change fees for flights to Seville, Córdoba and Badajoz during the alert window. Road authorities have banned heavy goods vehicles from vulnerable stretches of the A-4 and A-66 in the afternoons, while ride-sharing firms Cabify and Uber have capped surge pricing in affected cities to prevent profiteering. For global mobility managers, the practical advice is to schedule site visits and client meetings for early morning, ensure employees carry written evidence of air-conditioned accommodation (required for some occupational-health insurance policies) and to remind assignees that heat-related sick leave is now explicitly covered under Spain’s labour-risk prevention law. The heatwave coincides with the “Operación Retorno” weekend when Spanish families drive back from coastal resorts, adding pressure to transport networks. AEMET warns that further heat episodes are likely in late July, meaning contingency planning should remain in force all month.
