The Lowdown
Alright folks, Rusty here. Let's have a straight look at what’s coming for Rhossili over the next couple of weeks. Gotta be honest with you, the overall pattern is a tough one – there’s a whole lot of windy, choppy, and just plain messy conditions ahead, with the odd little glimmer of something rideable.
Right, starting from today, Wednesday the 9th, the sea state is a real letdown. We’ve got a 4ft WSW swell, but it’s getting hammered by a cross-onshore NW wind at 9 mph. The wave energy is moderate at best (197), but it’s blown out and choppy. The water is sitting at 66°, which is over 5° warmer than normal for this time of year – that's very unusual, but with the onshore junk on top, it's not helping the quality one bit.
Moving into Thursday the 10th, it’s more of the same grim story. The morning is a complete mess with a short-period 3ft SW windswell (4-second period) and a cross-shore wind. By the afternoon, the wind cranks up to 22 mph from the SSW, pushing a lumpy 7ft swell (moderate energy at 340). That’s getting into the zone where it’s only for the experienced, but even they won’t enjoy it in these winds.
Friday the 11th offers a sliver of hope, but it’s marginal. The morning shows a 5ft WSW swell, period lifting to 9 seconds with light cross-onshore breeze. It’s still not clean, just "marginal," so you’d be paddling into weak, bumpy lines. The afternoon gets blown out again.
Saturday the 12th is a write-off – fresh cross-onshore winds and lumpy, poor surf. Sunday the 13th morning rides that same line of “marginal” with a longer 10-second period on a 4ft swell (energy 338). The cross-onshore wind is light, but it's still just enough to spoil it.
Now, here’s your one standout for the near-term. It’s on Tuesday the 15th. The morning has a 3ft WSW swell with a gentle cross-offshore breeze from the SE. The conditions are described as "clean" – that’s the key word. The wind state is clean, and the surf is ordinary but surfable. However, the real beauty moment is Tuesday afternoon. The wind drops to glassy, a slight air from the SE at just 3 mph, and the swell fills in a touch at 4ft. It’s weak energy (98), but the *glassy* wind state makes up for it. This is your window for a clean, stress-free session on a longboard or a funboard. The crowds at Rhossili are only sometimes an issue, so you might have it pretty quiet.
After that brief taste, we slide right back into the junk. Wednesday the 16th brings a much bigger, stronger 8ft W swell hitting with a period of 9 seconds (strong energy at 930). But a fresh 19 mph cross-shore wind from the North turns that into a lumpy, tricky mess. That’s expert-only in these winds, and not much fun.
The second week is more of the same grey outlook. From the 17th through to the 24th, it’s almost solidly cross-onshore winds with poor to marginal conditions. There’s no clean window to recommend. The energy is mostly low to moderate on the smaller days. It’s a long, blank run of nothing special.
In short, don’t hold your breath for most of this period. The only real reason to paddle out is that afternoon on Tuesday the 15th for the glassy, clean conditions on small waves. Otherwise, setup looks more interesting for kite surfing than paddle surfing with all this cross-shore wind.
Rusty.

Information about the Rhossili Surf forecast
The above surf forecast table for Rhossili provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Rhossili can be found by selecting the local surf guide option on the grey menu. Our Rhossili 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 (Rhossili) 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 Rhossili 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.
Rhossili 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.
