On 5 September 2026, the Canary Islands government extended the pre-alert for expected high temperatures, bringing it into force from 12 noon local time on La Palma and Fuerteventura . The pre-alert already in force remains in place for affected areas on Tenerife and Gran Canaria . The warning is based on information from the Agencia Estatal de Meteorología and the Plan Específico de Emergencias de Canarias por Riesgos de Fenómenos Meteorológicos Adversos (PEFMA), the Dirección General de Emergencias said.
said. Specifically, the pre-alert applies in the municipality of El Pasoon La Palma. On Fuerteventura, it covers the island’s interior in the southern half and the south-east coast. On Tenerife, it remains in place in the highlands and mid-altitude areas (cumbres y medianías) of the southern and western slopes, the southern side of the Santa Cruz–La Laguna metropolitan area, and the mid-altitude areas and coast of the Valle de Güímar on Tenerife. On Gran Canaria, the pre-alert continues to cover the highlands and the east-, south- and west-facing slopes.
Meteorologists expect very high temperatures in some areas. El Paso on La Palma is forecast to reach up to 34 °C. Much of the southern half of Fuerteventura could see temperatures above 34 °C and locally above 36 °C. Temperatures of 33 to 34 °C are widely forecast on Tenerife; in the Valle de Güímar, local highs of up to 37 °C are possible on Sunday, 6 September 2026. On Gran Canaria, temperatures of up to 37 °C cannot be ruled out locally in parts of the Cuenca de Tejeda, at mid-altitudes and in low-lying areas exposed to the south or west. Higher night-time temperatures are also forecast, locally barely falling below 26 °C and making it harder to recover.
The authorities point to increased forecast uncertainty, as this is a heat-driven, humid event with mid-level cloud cover; isolated thunderstorms with lightning are possible. The Dirección General de Emergencias is monitoring the situation continuously and has said it will issue further updates. The public is advised to follow the published self-protection guidance.
According to the authorities, the combination of high daytime and night-time temperatures increases the strain on vulnerable groups; the risk of vegetation fires also rises in exposed high-altitude areas. The figures and locations cited are based on information from the Gobierno de Canarias and forecasts from the Agencia Estatal de Meteorología dated 5 September 2026.
