Scuba Diving Conditions Report South Wales, Cardiff, Porthcawl, Aberavon, Swansea, Llanelli, Stackpole Quay


The Sea conditions as through out the winter have not been good around the coastline of Newport, Cardiff, Porthcawl, Aberavon, Swansea and Llanelli, the swells and big, sea state rough, visibility low, and all round bad conditions for Scuba diving and snorkelling.

Now the weather were hopefully start to change for the better, with lighter winds and sunnier longer days, we are still running all the PADI courses in the system including PADI Open Water Diver, PADI Advanced Open water Diver, PADI Rescue Diver and PADI Divemaster as well as the usual specialities, the courses are run through out the year in preparation for the diving season or diving abroad.

Scuba Diving Conditions Report for Cardiff, Swansea & South Wales

Swell is set to be low on the South Wales coast this weekend and the northerly wind should help to keep it low. The tidal range is also good this weekend, with a high of approx. 8m and a low of around 3m we should have acceptable conditions for diving, particularly in the sheltered bays, such as Stackpole Quay will see the better conditions. Remember the rule of twelfths and look to dive on the incoming tide, which this weekend will be around 11:00 – 13:00.

You’ll still need to keep an eye on the visibility, which could be poor due to the water movement and unsettled conditions we’ve had in South Wales this last week but generally we expect the water course to be settled and safe.

Swell size, wind strength and wind direction are all set to change for the worse into the early part of next week meaning conditions could very well become unsafe, so it’s vital you track the swell, tidal conditions and wind before making any decision to dive, ensuring you are aware of the expected conditions at both the beginning and end of your planned dive(s).

Scuba Diving Training in Cardiff, Swansea & South Wales

A break in training this weekend after last weekends PADI Open Water course at Hebron Hall in Cardiff. With the conditions we’re expecting this weekend perhaps we’ll just head out for a pleasure dive somewhere along the South Wales coastline instead.

CAUTIONS – As always with UK diving at this time of year, you need to ensure you have the correct thermal protection, including Hoods, Gloves, Dry, or Semi-Dry, suit and base layers. Be sure to check local tidal times and conditions before making any dive.

Scuba Diving Cardiff, Swansea, South Wales, conditions report 26.02.2016 – The wind has dropped and the swell is down but unfortunately the visibility is poor around the South Wales coast including areas around Cardiff, Swansea, Burry Port and round to Tenby. The water temperature is high for the time of year at 8 – 10 degrees in places.

The best day for calm conditions will be Sunday with the swell and wind calming, the tides are high and must be used to there fullest extent. The high tide is 8am – 8.30pm therefore the best time to dive would be 7am onwards and possibly up to 10.30am on the dropping tides, after this time the rule of twelfths will come into play and the tide will run significantly faster after 10.30am.

The best areas will be Stakepole Quay in Tenby then towards the pembrokeshire coastline, with areas far more protected in these regions. Area close to Cardiff and Swansea will be Dive able but with limited visibility.

The inland areas have still got good visibility and water temperatures for the time of year, due to these facts we will be offering our PADI Open Water course training dives in the inland sites as well as the PADI Advanced Open Water Course and the PADI Rescue course.

Next week will see the start of our next PADI Open Water Diver course in Cardiff, for students from all over the South Wales region.
