Sagunto activates orange alert for extreme heat on 8 September
Valencia's 112 emergency service and Spain's national weather agency AEMET issued an orange heat alert for the northern coast of Valencia province on Tuesday, 8 September, with temperatures up to 39°C forecast for Sagunto between noon and 8pm.
The most intense heat episode of this part of September in Sagunto came on Tuesday 8 September, when Valencia's 112 emergency service, together with AEMET (Spain's national weather agency), raised the heat warning to orange level for the northern coast of Valencia province. The alert was active from noon until 7:59pm that day, with forecast temperatures reaching as high as 39°C.
An orange warning, as AEMET explains on its own official alert scale, means "significant risk": vulnerable people and property, or those in exposed areas, could suffer serious harm if precautions are not taken. It is not simply an informational notice, then, but a call to step up protective measures for as long as the heatwave lasts. AEMET's own scale includes three other levels: green, meaning no significant weather risk; yellow, a low risk affecting only certain activities; and red, reserved for the most extreme episodes, when the danger is no longer limited to vulnerable groups but extends to the population as a whole.
This alert system is not exclusive to Sagunto: Valencia's 112 emergency service coordinates the same protocol along the entire Mediterranean coast of the Valencian Community, divided into different warning zones that can reach different levels depending on the intensity of the heatwave at each point — a coordination system that allows emergency protocols to be activated uniformly across the region even though the effects of the heat vary from one district to another. The orange level on 8 September applied specifically to the northern coast of Valencia province, the zone that includes Sagunto.
Given this situation, Sagunto City Council reminded residents of the standard advice for extreme heat episodes: stay informed through official sources — the council itself, AEMET and the 112 CV emergency line — take shelter during the hottest hours of the day, and pay special attention to the most vulnerable groups, particularly children under 5 and people over 65, as well as anyone who is very overweight, chronically ill or taking certain medication. The municipal notice also stressed never leaving anyone inside a closed vehicle and keeping an eye on fluid intake for both young children and older people.
Among the practical tips, the council asked residents to limit sun exposure as much as possible and, when unavoidable, to wear light, pale-coloured clothing covering most of the body, especially the head, as well as using sun protection. It also recommended light meals rich in water and mineral salts — fruit and vegetables — drinking plenty of water, and avoiding prolonged physical exercise during the hottest hours.
For anyone needing a cool place to shelter, the council pointed again to its network of "climate shelters" — public spaces set up months ago and expanded further this summer. In total, the municipal network now includes 24 air-conditioned indoor spaces and 7 shaded parks spread across Sagunto, Puerto de Sagunto (the coastal district) and Almardà, two more locations than in 2025, widening coverage for heat episodes like this orange alert. The full list, with addresses for each location, remains available as a downloadable PDF on the council website, so any resident can find the shelter closest to home or work. This kind of facility gives residents a free, accessible space to shelter from the heat during the riskiest hours, without needing air conditioning at home — something not every household in the municipality can afford. The network was launched in June 2026, right at the start of the hot season, as the council's direct response to a string of high-temperature episodes already affecting the district at the time, and it has remained operational, with occasional additions, throughout the summer.
The 8 September warning was not an isolated event this summer in Sagunto: a combination of above-average seasonal temperatures and heat lasting for much of the day has led to similar alerts being issued several times in the district this year, which has ended up turning the shelter network into a structural response, not just a one-off measure, against heatwaves in the municipality. For the council, combining early information, clear advice and a physical network of cool spaces is the formula it is using to reduce the impact of a phenomenon that, according to weather services themselves, tends to repeat every summer with greater frequency and intensity.
