President Pedro Sánchez visited the Vall d'Uixó wildfire command post on Monday to warn that a heat wave is complicating firefighting efforts [1].

The visit highlights the escalating danger of Spain's summer fire season, as extreme weather threatens to expand the blaze and endanger more residents in the Castellón province [2].

Sánchez arrived at the advanced command post in the Serra d'Espadà region to coordinate with emergency services [2]. He said that "quedan horas difíciles, horas complejas" — difficult and complex hours remain — as the government battles the flames [3]. The president called for extreme precaution across the entire country to prevent further ignitions during the incoming heat wave [5].

The fire has already forced the evacuation of more than 16,000 people [4]. Emergency services are currently managing a fire perimeter of 48 kilometres [6].

Reports on the total area affected vary between sources. El Periódico reported that the fire has burned 7,200 hectares [2], while Cadena SER cited a figure of 6,500 hectares [6].

Sánchez announced that the government would declare the area as gravely affected to facilitate recovery and support for the impacted communities [7]. The president said that the coordination between national and regional authorities remains the priority as temperatures rise [5].

Firefighters continue to work in the Serra d'Espadà region, where the rugged terrain and dry conditions have hindered containment efforts [2]. The president said that the coming days will be critical for the safety of the region [3].

"Quedan horas difíciles, horas complejas"

The intersection of a massive wildfire and an incoming heat wave creates a feedback loop that increases fire volatility and complicates evacuation logistics. By declaring the area gravely affected, the Spanish government is triggering specific legal and financial mechanisms to expedite aid, signaling that the economic and environmental damage in Castellón is expected to be severe.
