Alright, folks, Rusty here. Let's have a honest look at what’s on the cards for the next couple of weeks at Llangennith. Straight up, I’ve got to be real with you – it’s a tough stretch ahead. There’s no proper surf to speak of for a solid week, with nothing worthwhile showing until the 10th of July. After that, it’s a frustrating pattern of weak swell and messy wind.

The first decent chance we get is on the morning of Friday the 10th. We're looking at a tiny 2 ft swell from the west, but the magic is in the wind: an offshore breeze from the east, which should make for some clean, if very small, waves. Combined wave energy is weak at just 41. For a complete beginner on a foamie, you might find something to practice pop-ups on, but anyone else is going to be struggling. That afternoon the wind swings cross-off, and the window closes.

Saturday the 11th morning offers a similar story – a weak 1 ft swell from the WSW with a cross-off breeze keeping it clean, but it’s still very ordinary. This is the kind of surf where you’re scratching for anything rideable.

We then hit a dry spell again through the middle of the week. The morning of the 14th shows some hope with a 1.0 ft swell and a cross-off breeze, but it’s still far from exciting.

It’s not until the weekend of the 18th and 19th that we see any real size, but it comes with a curse. On Saturday the 18th morning, a 4 ft west swell rolls in, with combined energy cranking up to a moderate 144. However, it's arriving with a fresh cross-onshore wind, making conditions lumpy and choppy. This is beginner territory only if you’re happy getting beaten up. For experienced surfers, the quality just isn’t there.

Sunday the 19th morning is the biggest of the whole run – a 5 ft west swell with moderate cross-shore wind, pushing energy to 262. But again, it's a messy cross-chop. The short period of 7 seconds doesn't help, making for weak, crumbly waves. Honestly, with these strong winds and messy conditions, this looks way more appealing for a kite surfer than a paddle surfer.

All in all, it’s a pretty grim outlook. The water temperature is about average for the time of year, but the surf gods are not smiling on us. We’ve got a long gap of poor conditions, and when the swell finally does arrive, it’s blown out. Keep your expectations low and your fingers crossed for a change in the forecast.

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.
