Alright, Rusty here. Let’s have a look at what’s on the cards for your local stretch.
Right, I’ll be straight with you – the next 16 days are pretty quiet. There’s no proper swell to speak of, so don’t expect to be getting wet in anything worthwhile. We’re looking at a long, dry spell with tiny waves and plenty of wind.
Let’s start at Tenby (South Beach). Through the whole first week and into the second, the swell heights are tiny, mostly around 0.3 ft to 1 ft. The combined energy is weak too, with values between 5 and 107 – that 107 mark on Monday 13th July morning is the highest, but it’s still only moderate energy and the wind is messy, cross-shore, not doing us any favours. That morning has swell at 4 ft from the east, but period is only 5 seconds, so it’s a lumpy, wind-affected mess – not one for the log.
There are glimpses of clean conditions, like Wednesday 15th July afternoon with light offshore from the northwest, or Friday 17th July with offshore breezes, but the swell is just too small to bother with. A couple of afternoons late in the month, like 22nd July, see a slight bump to 2 ft from the west, but with a short 5-second period and a fresh breeze, it’s still poor.
Honestly, for the whole 16-day window, there isn’t a single standout. The water feels about average for this time of year, nothing unusual. If you’re desperate for a paddle, maybe a tiny clean-up set on Wednesday 15th afternoon or Friday 17th afternoon, but it’s more of a float than a surf. This is one of those stretches where the forecasts can change, but right now, it’s looking like a blank run.
Stay tuned and keep an eye on it, but for now, maybe tune the boards.
Rusty.
