SCUBA DIVING CONDITIONS SOUTH WALES CARDIFF, SWANSEA, LLANELLI, CARMARTHENSHIRE
Weather has definitely turned for the worse over the past few days and will continue into next week. High winds and heavy rain will affect all areas along the South Wales coast for Scuba Diving with entrance and exit conditions becoming harder and possible unsafe in certain areas. Visibility will also be lacking after the wind, swell and rainfall . The better option would be to head inland to the protected scuba diving sites which are far more protected from the elements and visability will be better. We are running the PADI Open Water Diver programme accross the South Wales region and have several students now ready to go onto complete the four Open Water Qualifying dives for the full PADI Open Water Diver Certification. This will be held either on the coast if conditions are suitable or inland at dedicated diving facilities.

This will cause rough conditions inshore for diving areas especially on the South Wales coast and also effect the visibility at all diving locations. Winds are especially high on Tuesday causing high seas and very rough coastal conditions unsuitable for diving in the area especially around Cardiff and Swansea.
