The province of Santa Cruz de Tenerife, encompassing the islands of Tenerife, La Palma, La Gomera, and El Hierro, will be spared the most extreme temperatures of the heatwave affecting mainland Spain. The presence of trade winds and cloud cover on the northern slopes will act as a thermal shield, moderating temperatures in these parts of the archipelago.
Recent data from the State Meteorological Agency (Aemet) already indicated a respite in the western province, with moderate values such as the 27.7 ºC recorded in the Anaga massif.
Despite the general trend of mild humidity, each island's topography will create nuances. In Tenerife, the northern coast and metropolitan area will benefit from the cloud-trade wind shield, while the south, peaks, and exposed midlands will feel the heat more intensely. On La Palma, the north and east will remain cool due to the trade winds, contrasting with the higher areas of the Caldera de Taburiente and the Aridane valley. La Gomera will have its northern strip and the Garajonay forests protected by the sea of clouds, with temperature rises mainly affecting the southern and southwestern midlands. El Hierro will record the most contained values, with coolness in the north and localized heat spikes in the interior highlands and south-facing slopes.
Compared to the red alerts and extreme highs on the mainland, the western islands will experience heat typical for the summer season, without reaching excessive values.
