Las Palmas de Gran Canaria (EFE) ).
The delegation of the State Meteorological Agency (Aemet) in the Canary Islands published this Thursday on its Twitter account a graph that shows the evolution of the surface temperature of the sea around the islands since 1940.
The sawtooth-shaped graph shows that that value has oscillated over that period from just minus 18.5 degrees in the early 1970s to as high as 20.8 this spring.
And above all, the trend since 1970 is striking: since that date, it can be clearly seen how the curve rises with increasing maximums and minimums.
In all this series, only on one occasion had the surface sea water temperature exceeded 20.5 degrees, at the beginning of the 2010s, with a value slightly above that level. EFE
