Eleven of the victims lost their lives this past weekend, when warm weather encouraged bathers to take a dip.
Authorities have appealed to Poles to choose bathing areas patrolled by lifeguards and never swim after consuming alcohol.
They also cautioned people not to recklessly jump into the water without first making sure it is safe.
Last year 545 people drowned in Poland. Alcohol was a factor in 126 of the incidents.
