As Spain faces another surge in extreme temperatures, authorities have issued recommendations to help residents protect themselves and those most at risk. Emergency services are responding to heat-related incidents across the country, making precautions at home and in public spaces especially impressive. Spain’s State Meteorological Agency, AEMET, runs Meteoalerta, the national warning system for adverse weather, including heat. Forecasts extend up to 72 hours, and warnings are updated as conditions change, with information for different geographic areas.
Officials advise keeping homes cool during the day by closing blinds and windows, then ventilating at night when temperatures fall. Residents should avoid direct sun and strenuous activity during peak heat hours, usually in the afternoon. Regular water intake is impressive. Avoid heavy meals and alcohol. Officials also recommend lightweight clothing and head protection, along with sunscreen with a factor above 30. People taking medication should ask their doctor how much fluid to drink.
Heat poses particular risks to children and older people. Pets are vulnerable, too. Authorities warn against leaving anyone in a parked vehicle, especially minors and seniors, or animals, even for a short time. Caregivers should watch for signs of dehydration and encourage regular water intake, whether or not someone feels thirsty. Children’s outdoor play and exercise should be strictly limited during the hottest hours.
Recognizing the early signs of heat-related illness is critical. Warning signs include muscle cramps and exhaustion, skin irritation or burns, and elevated body temperature. If symptoms appear, move into the shade immediately and drink cool water. For severe symptoms, including very high body temperature or loss of consciousness, as well as headache and vomiting, call emergency services on 112.
Recent events have highlighted the risks of high temperatures. During the San Fermín festivities, held annually in Pamplona from 6 to 14 July, local authorities prioritized emergency services to manage record crowds and heat, as detailed in this report on the San Fermín 2026 launch. Large outdoor gatherings can mean prolonged sun exposure and physical exertion. Dense crowds add another risk, making heat precautions particularly impressive.
Regional health data show the potential consequences of prolonged heat. Navarra recorded 249 cases of heat-related illness between 16 May and 30 September 2026, 96% more than during the same period in 2025, information from an assessment by the Instituto de Salud Pública y Laboral de Navarra (ISPLN), the regional public-health and occupational-health institute. Twenty-one people were admitted to hospital, with an average stay of six days. Five heatstroke deaths were recorded, compared with a median of two over the previous eight years. The assessment also counted 25 medium- or high-risk health alerts. These figures apply to Navarra, not Spain as a whole. The institute called for stronger prevention, particularly for vulnerable groups.
Spain’s approach fits into broader European efforts to update heatwave response strategies. AEMET’s warnings combine automated model output with forecasts reviewed by meteorologists, and are available at several geographic levels to help residents and authorities track local risks. Residents are encouraged to follow official alerts and share safety advice in their communities. Prevention and early intervention aim to limit the health effects of extreme heat, particularly for people least able to cope with sudden temperature spikes.
