The Canary Islands Government has issued a heat pre-alert for all of the islands as another spell of very hot weather is expected to begin on Sunday (5th July). Temperatures could reach as high as 38°C in some areas during the first half of next week.

The pre-alert comes into force at 8:00am on Sunday and covers the whole archipelago. It has been issued as a precaution after weather experts forecast several consecutive days of unusually high temperatures.

The hot weather is being caused by a mass of warm air moving north from Africa. The first areas to feel the heat will be Gran Canaria and inland parts of Fuerteventura on Sunday, before it spreads across the rest of the Canary Islands from Monday.

Forecasters expect the hottest days to be between Tuesday and Thursday. Inland and south-facing areas of Gran Canaria are likely to see temperatures of 34°C or higher, with a chance that a few locations could reach 38°C.

In Fuerteventura, temperatures are expected to climb to around 33°C, while inland parts of Tenerife could see highs of 32°C to 33°C. Other islands may also experience rising temperatures as the heatwave develops.

The hot air will also bring very dry conditions, especially in inland and higher areas. This increases the risk of wildfires, so residents and visitors are being urged to take extra care, particularly in rural areas.

A light layer of dust from the Sahara is also expected to reach the eastern islands. However, forecasters say it is not expected to be dense enough to cause major disruption.

Health officials are advising people to avoid being outside during the hottest part of the day, usually between late morning and early evening. Drinking plenty of water, wearing loose, light-coloured clothing and staying in cool or air-conditioned places whenever possible can help reduce the risk of heat-related illness.

Extra care should be taken with young children, older people and anyone with long-term health conditions, as they are more vulnerable during periods of extreme heat. If you are planning walks, excursions or other outdoor activities, check the latest weather forecasts before setting off and avoid strenuous exercise during the hottest hours.
