Visibility Is One of the Biggest Unknowns in
UK Diving

In the UK and Ireland, underwater visibility can change significantly from one day to the next.

Weather alone doesn’t reliably predict it
Algae blooms can reduce visibility overnight
Nearby sites can vary considerably

For centres running training dives, guided dives or charter trips, this variability can make planning and communication more challenging — particularly when divers are travelling.
