How afraid should we be of jellyfish off UK shores?
Summary
Jellyfish are commonly seen off the coast of Scotland, especially during July and August when the sea is warmer. While their stings can be painful, they are rarely dangerous. Jellyfish numbers rise due to warmer water, more food, and calm ocean currents pushing them closer to shore.Key Facts
