The Lowdown
G’day, it’s Rusty here.
Look, I’m not going to sugarcoat it – the next week and a half is going to be a proper struggle. We’ve got a long, flat, and messy run ahead of us. From now through to around the 12th of August, there’s basically nothing worth paddling out for at Roaches Reef. The swell stays tiny, mostly under 3 feet, with weak energy readings (down in the single digits and teens). You’re looking at a lot of cross-shore chop and lumpy conditions, with the only saving grace being a few clean morning windows when the breeze drops. But even then, the swell is just too gutless to do anything with. It’s a classic dry spell, and it’s going to feel like forever.
The first real sign of life doesn't show up until the morning of Thursday the 13th of August. We finally see a pulse of swell push through at about 3 feet from the WSW, and the wind goes glassy. The energy is still weak-ish at 162, but it’s the first surfable waves we’ve seen in a while. Still pretty ordinary, but at least you can get wet without getting frustrated. That afternoon the wind swings west and picks up, chopping it all out, so don’t sleep on that early session.
Friday the 14th of August morning is similar – a touch smaller in size but still glassy, with a bit of push from the WSW at 3 feet. That’s another window worth having a look at. After that, the wind gets up again and we slide back into mediocrity for the weekend, with onshore breezes ruining what little swell there is. It’s all pretty average and the energy drops back into the double digits.
Now, here’s the one that’s got my attention. The model is showing a proper pulse for the morning of Tuesday the 18th of August. This is over a week away, so take it with a grain of salt, but it’s a real standout in an otherwise bleak outlook. The swell jumps right up to about 8 feet from the WSW, and the energy reading is a solid 927. That’s strong. The wind is cross-off and clean, so the face of Roaches Reef should be holding shape. It’s a reef break, so this kind of bigger, longer-period groundswell is exactly what it wants. This is the one to circle on the calendar.
That afternoon it gets even bigger at around 8 feet, and the energy kicks up over one thousand (1023), but there’s a risk of thunderstorms and a fresh cross-off breeze. It’s going to be powerful and a bit on the wild side. If you’re not an expert, this is the day to watch from the sand. The early session on Wednesday the 19th still has good energy (311) with glassy conditions and a solid 5 feet of WSW swell – that’s a great backup option for the less experienced.
So, there’s light at the end of the tunnel. Be patient, don’t burn yourself out on the junk, and be ready to go when that Tuesday-morning swell hits.
Rusty.

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.
