The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for Llangennith over the next couple of weeks.
Right off the bat, I gotta be straight with you: the next week and a half is looking pretty flat. We’re talking about a real dry spell from now until the 24th of July. The swell is tiny, mostly under 1 ft, and the combined wave energy is weak, barely cracking 30 (30) at its best. It’s just not worth paddling out for. There are a few glassy mornings, like the 14th and 18th, but with no waves to speak of, it’s a complete write-off for surfing. You’d be better off checking the tide pools.
Then, around the 25th of July, we finally see a pulse of life. The swell picks up to 3 ft from the WSW, but the period is a short, weak 5 to 6 seconds. The combined energy is still low to moderate, hitting 55 (55) on the morning of the 25th. Unfortunately, the wind is a mess – cross-onshore and choppy. The morning of the 25th is the only real window, with a clean-looking cross-offshore breeze, but the waves are still just “surfable but very ordinary.” It’s not a standout, just a hint that the ocean is waking up.
The real event, if you’ve got patience, is brewing for the end of the month. From the 27th of July, the swell bumps up to 4 ft from the WSW, with a period of 6 seconds. The combined energy is moderate, hitting 167 (167) on the morning of the 27th. But the wind is a problem – a fresh breeze from the WNW, which is cross-onshore, making it lumpy. The 28th of July morning looks a little more manageable with a 3 ft swell and lighter wind, but it’s still onshore.
The best call of the whole run? Honestly, it’s a tough sell. The 25th of July morning is the only time the wind and waves even sort of line up. The swell is 3 ft from the WSW, and with that light, clean cross-off breeze from the NNE, it’ll be the most surfable we’ve seen in weeks. But don’t expect perfection – it’s a beach break, the period is short, and the energy is low (55). For a beginner, this is actually a fun, small day. Just don’t expect barrels.
Overall, this is a classic summer flat spell for Llangennith. The ocean is taking a long nap, and the forecasts can change, but for now, the best advice is to keep the board in the car and wait for the 25th morning.
Rusty.

A general guide to surfing at Llangennith can be found by selecting the local surf guide option on the grey menu. Our Llangennith surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Llangennith) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Llangennith may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
