The Lowdown

Alright folks, Rusty here. Let’s take a good, hard look at what’s heading our way.

To be straight with you, this 16-day window is a tough one. The numbers are stubbornly small and the winds are mostly messy, so don't go expecting any hero waves. We’ve got a long, lean run here with hardly a pulse - honest swells are hard to come by. The water temperature is sitting at a very unusual 68°F, which is a massive 7°F warmer than average for this time of year. That’s a strange feeling for sure.

Things start off flat and ugly. From Wednesday, July 29th right through to the end of the month, it’s a write-off. The swell is tiny, barely 1.0ft to 2ft, and the wind is mostly cross-on or onshore, blowing between 6 mph and 16 mph, making for lumpy, choppy, poor surf. Nothing to even bother paddling out for.

We finally catch a tiny break on Sunday, August 2nd. The morning session sees a light easterly offshore wind at 6 mph with a glassy clean surface, but the swell is a pathetic 1ft from the WSW. The energy is weak, just 23 on the scale. By the afternoon, it goes glassy with no wind at all, but the waves drop to 1.0ft. It’s clean, but it’s barely rideable.

Monday, August 3rd offers the closest thing to a highlight in this whole outlook. The morning is glassy, barely a breath of wind from the NE at 3 mph, and the waves push up to 2ft from the WSW with a period of 9 seconds. The energy is still low at 55, but it’s the most promising window we’ve got. It's surfable, but it's very ordinary. The afternoon turns cross-on and choppy again, so don't sleep in.

The rest of the first week into the second week is a real struggle. From Tuesday, August 4th through Sunday, August 9th, we see mostly onshore or cross-shore winds with swell heights bouncing between 0.3ft and 3ft. The only bright spot is the occasional clean, glassy spell like on the Friday, August 7th afternoon, but the swell is a mere 0.3ft with a 12-second period – that’s a groundswell, but there’s no power behind it, just a long wait for a tiny wave.

Into the second week, from Sunday, August 9th onward, it gets bleak. Winds pick up to 9 mph to 19 mph, mostly cross-on or onshore, with swell sizes falling to 0.3ft or 0.7ft and energy readings dropping to single digits. It's flat, choppy, and not worth the effort. The strongest energy we see all that week is a meagre 73 on the 9th, but with fresh onshore wind, it's a mess.

There’s no standout here, not a single session that would make me say, “That’s the one.” The best you can hope for is the glassy, tiny conditions on Monday, August 3rd if you’re desperate for a paddle and want to feel the warm water. Otherwise, for paddle surfing, it’s a blank run. The setup and the wind over the bigger days look far more interesting for kite surfing than for a surfboard.

Stay patient, lads. Forecasts can change.

Rusty.

Information about the Llangennith Surf forecast

The above surf forecast table for Llangennith provides essential information for determining whether the surfing conditions will be good over the next 16 days. 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.

Llangennith is 24 km (15 miles) from Swansea. If you plan a holiday in Wales - Gower, look for hotels and other accommodation in Swansea. Swansea has rooms for a wide range of budgets as well as car hire and transport links.
