The Lowdown
Alright, let’s get into it. The next couple of weeks are looking pretty flat and frustrating for most of us, to be honest. The swell window is just not lining up for Roaches Reef, and we’re going to have to be patient.
Right now, and through the start of the week, there’s basically nothing doing. We’re talking about tiny, weak swell with a messy cross-shore wind. The morning of Saturday the 8th has a bit of a bump, but it’s only about 0.3ft and choppy. Not worth getting wet for. The weekend is a write-off, and it stays that way straight on through to the middle of next week. We’ve got a long stretch of small, weak energy and cross-shore winds. The morning of Monday the 10th has a little bit of clean texture, but the swell is still only 0.7ft, so it’s not going to break properly.
Things start to get a bit more interesting later in the week. The morning of Thursday the 13th sees a bit more life in the water. The swell picks up to 3ft from the WSW, with a longer period of 11 seconds. That’s groundswell, and it’s got a bit more push to it. The wind is light cross-offshore, so it should be clean. This is the first real chance of a wave, but it’s still marginal. The energy is moderate (204), but the size is just not there for a proper session. The afternoon gets a bit more size, hitting 3ft, but the wind swings onshore and chops it up.
Friday the 14th is a bit of a tease, with clean conditions but the swell drops back to 3ft and the period shortens, so it loses its grunt. The glassy morning on Saturday the 15th is beautiful, but there’s barely any swell at 1ft. It’s a lake out there.
We go through another dry spell early in the following week, with the swell staying small and the winds mostly onshore or cross-shore. The morning of Tuesday the 19th is a standout on paper, finally. The swell jumps to 5ft from the W, and the wind is clean cross-off. The period is a bit short at 7 seconds, but the energy is now strong (230). This is the first time it looks like a real surfable day. The afternoon jumps to 5ft, but the wind gets fresh and lumpy, so that morning window is the one to target.
The morning of Wednesday the 20th looks even better. Swell holds at 5ft from the W, with a longer period of 8 seconds, and the energy is really pumping at 498. The wind is cross-off and clean. This is the pick of the whole forecast. It’s still not massive, but it’s got enough power for a proper session on the reef. The afternoon backs off a little to 4ft, still clean.
After that, the swell fades fast. The end of the window is back to small, clean but weak conditions. The Friday and Saturday mornings have some offshore wind, which is nice, but the swell is only 2ft and 1ft. Not worth the paddle.
So, the honest truth is, there isn't a lot on offer. The one day that looks like it could be genuinely fun is the morning of Wednesday the 20th. That’s your best bet—a couple of weeks out, so don't hold your breath, but it’s something to hope for. The morning of the 19th is the backup, but the period is shorter. Everything else is just flat and frustrating. For a spot like this, a blank run is pretty normal. The water’s still warm, though, so it’s not all bad.

Information about the Roaches Reef Surf forecast
The above surf forecast table for Roaches Reef provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Roaches Reef can be found by selecting the local surf guide option on the grey menu. Our Roaches Reef 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 (Roaches Reef) 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 Roaches Reef 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.
Roaches Reef is 11 km (7 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.
