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


There is a possibility of getting in the water over the next couple of days, the swell and winds are dropping around the coastlines of Cardiff, Swansea, Stackpole, Camarthen so exit and entrance may be plausible to scuba dive from safe sites. Visability however is low due to recent swells and high winds so again inland may be the better option for the hardy UK scuba diver.

Our PADI Open Water Courses and Advanced Open Water Courses are in full flow with students now preparing for the Open water dive sections of the course. The dates will be into May and June initially for the qualifying dives, taking PADI Open Water Referral Diver students to their next step to becoming fully qualified divers.

Conditions Report for Scuba Diving in Cardiff, Swansea & South Wales

We could see acceptable conditions for Scuba Diving on the South Wales coast this weekend. Swell is set to be low and we have North / North East winds, which should keep the swell low. We have had some fairly unsettled conditions recently and are expecting some more heavy rain on Friday so visibility could be a problem.

For the best conditions head to the more sheltered bays, such as Stackpole Quay and Oxwich Bay and always remember the rule of twelfths, ensuring you dive on the incoming tide. Be aware of wind direction changing, Southerlies and Westerlies could lead to unacceptable conditions, and increasing swell size, particularly for a shore dive.


If you want to be confident of getting a dive in, the best option is to head inland. The National Diving and Activity Centre (NDAC) in Chepstow will offer diving less affected by the environmental conditions.

Scuba Diving Training in Cardiff, Swansea & South Wales

The instructors have been travelling all over the UK these last weeks, putting on PADI Open Water Diver courses for schools across the South East of England. This weekend they’re having a break from training but will be back next weekend taking students through the referral part of the PADI Open Water Diver qualification. We also have some Advanced Open Water course coming up in June.

CAUTIONS – We’re still going to need to take sensible precautions with regards to thermal protection as water temperatures are still going to be quite low. If you are planning to dive off the coast in South Wales, ensure you are aware of the changing conditions, making sure you know the conditions for both the beginning and the end of the dive.

We should see low swell with acceptable wind strength across the weekend. However we’re set to see some huge tides over the next few days, 9 – 10m creating some very challenging conditions. Certain areas of South Wales could be an option with the depth of the tide allowing you to keep within the protection of the bays in Swansea but you’ll need time your dive to be within the 2 hours before high tide and will also need to be aware of the effect the tides will have on visibility before making any decision to dive.

In our opinion the best option is to head to one of the inland diving sites here in Wales to reduce the impact of the environment conditions.

Scuba Diving Training in Cardiff, Swansea & South Wales

This weekend sees us back at Hebron Hall in Cardiff taking our next group of PADI Open Water Diver students through their confined water dives and theory sessions. Upon successful completion of these they’ll be able to complete their open water dives, either with ourselves at The National Diving and Activity Centre in Chepstow or with any PADI Dive Centre throughout the world.

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.
