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).
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.
