The popular holiday hotspot of the Canary Islands has been put on a new heatwave alert with a special warning in place for Gran Canaria.
Weather agency, Aemet, says maximum temperatures of up to 37C are expected from Sunday.
This will be the third heatwave of the summer and there is also a warning that due to the wind, there will be strong waves of up to 6ft high.
This week, one man died and five others were saved from a popular beach in Tenerife when they all got into trouble due to the currents.
The man who died on Friday was aged 29 but his nationality was not released.
He was pulled from the sea with signs of drowning in the resort of Callao Salvaje in the south of the island.
Five other people were also rescued.
One of them, a 28-year-old man, had a mild anxiety crisis while the other four people did not require health care.
Emergency services received several calls just before 1pm warning of the presence of five or six people in distress at sea.
A helicopter hoisted the two men but the 29-year-old was in cardiorespiratory arrest and could not be revived.
The 28-year-old man was taken to a local health centre.
Today's weather warning says the temperatures will soar on some of the islands despite cloudy skies.
Safety experts are urging tourists to take great care during the heatwave and to be aware of the potential dangers of the sea with strong underwater currents.
The warning also applies to swimming pools where tragedies can happen in seconds.
Yesterday, a two-year-old girl on holiday in Tenerife with her family was rescued from the pool of an hotel complex after nearly drowning.
The incident happened in the resort of Guía de Isora.
She was rushed to hospital but is reported to be recovering.
This comes as there were calls in the UK for a national hosepipe ban and compulsory water metering as the nation braces for drought.
The National Infrastructure Committee (NIC) has said water needs to start being managed better across the UK, otherwise the country could face a future of queueing for emergency bottled supplies "from the back of lorries".
The committee's warning - which has been backed by the Rivers Trust - comes as the first hosepipe ban of the year comes into force following the recent heatwave and one of the driest starts to the year on record.
Southern Water is to impose the temporary use ban on its customers in Hampshire and the Isle of Wight from Friday August 5.
This will mean hosepipes cannot be used to water gardens or clean cars, and ornamental ponds and swimming pools must not be filled.
The restriction is the first to be put in place in the region since 2012, with Southern Water saying river flows are down 25% as a result of one of the driest years on record.
A hosepipe ban was also introduced on Friday on the Isle of Man by Manx Utilities.
