Residents and holidaymakers across the Canary Islands can expect another hot summer day today, Friday, with temperatures climbing above 30°C in many areas and tropical overnight conditions continuing in parts of the archipelago.
According to the State Meteorological Agency (AEMET), Gran Canaria will be the hottest island, where temperatures could reach 34°C in inland and mid-altitude areas. Fuerteventura is expected to see highs of 32°C, as both islands remain under a pre-alert for high temperatures.
The warm weather will also continue after sunset. In the hottest parts of Gran Canaria, overnight temperatures are expected to remain between 24°C and 26°C, making for another uncomfortable tropical night. Similar overnight temperatures are also possible in some areas of Tenerife.
Anyone planning outdoor activities is advised to stay well hydrated, avoid prolonged exposure to the midday sun, and take extra care if hiking or exercising during the hottest part of the day.
Sea conditions
At sea, moderate to fresh northeast winds are expected, strengthening offshore in parts of the southeast and northwest. Rougher seas are likely in exposed areas, while more sheltered northeastern and western coasts will experience calmer conditions with light breezes.
