The Canary Islands Government declares a heat alert for maximum temperatures in Fuerteventura, Gran Canaria, and Tenerife starting Thursday, July 23. Values of up to 37 degrees are expected in some areas.
The Canary Islands Government has activated the heat alert for maximum temperatures on three islands of the archipelago due to the forecast of an intense heat episode. The measure, which depends on the General Directorate of Emergencies, will begin at 11:00 hours on Thursday, July 23, 2026, and will affect Fuerteventura, Gran Canaria, and Tenerife.
The decision is based on data provided by the State Meteorological Agency (Aemet) and is part of the Specific Emergency Plan of the Canary Islands for Risks of Adverse Meteorological Phenomena (PEFMA). Authorities have focused on areas where temperatures could soar, especially in the interior and midlands.
In Fuerteventura, the maximum temperatures are expected to range between 30 and 32 degrees Celsius, particularly affecting interior and coastal areas of the southeast. Gran Canaria will be the island that could record the highest values, with up to 34 degrees in the peaks of the Tejeda basin and in the south and west-facing midlands above 500-600 meters in altitude. In some low areas of southeast Gran Canaria, the thermometer could reach 37 degrees Celsius.
Tenerife will also experience a notable rise in temperatures, with estimated values between 30 and 32 degrees in the midlands and low areas of the south and the metropolitan area, with localised peaks potentially reaching 34 degrees. The alert covers the southern metropolitan area and various zones in the south of the island.
In light of this scenario, the General Directorate of Emergencies has issued a series of self-protection recommendations aimed at the population. Among the most common advice in such situations are to hydrate frequently, avoid sun exposure during the hottest hours of the day, stay in cool or air-conditioned places, and pay special attention to vulnerable groups such as children, the elderly, and people with chronic illnesses.
Authorities remind that the alert is the lowest activation level within the emergency system, but it serves to ensure that the population and involved services are prepared for a possible worsening of weather conditions. It is recommended to follow the evolution of forecasts through official channels.
This heat episode arrives in the midst of the Canary summer, a time when temperatures are usually high, although it is not common for such high values to be reached in the midlands. Aemet will continue to monitor the situation and may update warnings if necessary.
