In a statement, the organization recommends that the entire population stay away from the beaches this weekend, as temperatures are expected to rise.

The National Maritime Authority stresses that the beaches are not yet guarded by lifeguards, in addition to there being risks to public health because of the covid-19.

"The Maritime Police will increase in the coming days the surveillance and inspection on the beaches, with the objective of sensitizing the population and avoiding risky behaviours, safeguarding public health", the statement said.

The National Maritime Authority reinforces that "it is essential that the Portuguese follow the instructions and recommendations of the authorities and maintain safety behaviours, social distance and avoid exposing themselves unnecessarily to risk".
