Swimmers tempted to take a dip in Bristol's Floating Harbour have been told that it is "dangerous and against local by-laws".
With another sunny weekend under way, many people will be gathering at the water's edge to take in the views and enjoy the weather.
However, Bristol City Council has reminded people that swimming there is forbidden - despite an ongoing campaign for those rules to be relaxed.
In a post shared on Facebook, the authority warned: "Bristol's working harbour is not a place to swim.
"It's dangerous and against the local by-laws designed to ensure safety.
"The health and safety of all harbour users is our first priority and we urge people not to endanger themselves and others by swimming in this area."
The post was shared yesterday (Friday, June 4) a few hours after a group of wild swimmers staged a 'protest swim' at the Cumberland Basin.
They argue that the water quality is now safe enough to ease the swimming ban, at least at specific places along the Floating Harbour and under controlled conditions.
Campaigners have pointed to places like Copenhagen, where inner city bodies of water, canals and rivers have special swimming areas.
However, their swim was dispersed by the deputy harbour master who threatened them with prosecution if they are caught again.
Poor water quality, cold water shock, drowning and hidden objects beneath the water's surface are among the risks often referred to.
On Tuesday (June 1) emergency services carried out a major rescue operation, after four people got into trouble in the water near Cascade Steps.
Fire crews worked with the harbour master and Avon and Somerset Police to retrieve the group, with ambulances also in attendance.
The council's warning prompted more than 50 comments in response, with many expressing that they would like to see more options for wild swimming in the city.

Rachel commented: "There's no reason that an area of the harbour couldn't be designated for safe swimming, this happens in other European cities and would be a tremendous amenity for Bristol residents.
"There are many cold water swimmers in Bristol who have to travel up river a long way or drive to Clevedon Marine Lake to swim. I'd love to have a cold water swimming area in Bristol."
The Outdoor Swimming Society offers more information on its website about wild swimming and how to stay safe.
Information about the water quality in the Floating Harbour is regularly updated on the council's website.
