Nestled between the Irish Sea and the Bristol Channel, Wales features an impressive 2,700 kilometers/1,680 miles of coastline, inviting divers to explore its hidden marine treasures. The waters around Anglesey and Pembrokeshire are standout locations, where stunning coral carpets and steep walls shelter marine life like crabs, lobsters, and conger eels. Keen eyes may spot vibrant nudibranchs adding pops of color, while reefs teem with salmon and brittlestars.

The best Months to dive in Wales

Spring and summer typically bring warmer water temperatures, ranging from 10°C–15°C/50°F–59°F, improving comfort for divers. Visibility can reach up to 10 meters/33 feet during these months, though it can vary depending on local weather patterns.
Autumn and winter see cooler waters, ranging from 7°C–10°C/45°F–50°F, and reduced visibility due to increased rainfall and storm activity.
