The Lowdown
Alright, Rusty here. Let’s look at what’s coming our way for the next couple of weeks.
Right off the bat, I gotta be straight with you – this is a tough stretch. We’ve got a long, quiet gap staring us down. The first actual chance for a wave comes Wednesday morning, the 12th of August, at Rossbeigh Strand. That morning, a 5-foot SW swell with a 9-second period rolls in. The wind is light from the SSE, which gives us a clean, cross-off look. Combined energy is moderate at 373. It’s not world-class, but it’s the first sign of life after a flat start.
From there, it’s a grind. Thursday the 13th has a similar-sized swell, but the wind is all over the place, and the surf is choppy. Then we hit a real dry spell from Friday the 14th all the way through to Monday the 24th of August. That’s over a week of tiny, messy, or just plain useless surf. You’ll see some glassy mornings on the 16th and 22nd, but the swell is virtually non-existent – we’re talking 1 foot to 2 feet. Not worth paddling out for.
The standout window finally shows up for the experts. Monday morning, the 24th of August, the swell jumps to 7 feet from the west, with a period of 9 seconds. Combined energy is a solid 720, and it’s blowing clean from the NNE. That’s serious power. Keep in mind, at that size, it’s only for the experienced crew. The wind stays cross-shore through the afternoon, but the wave height drops to 6 feet.
Tuesday the 25th has a cleaner option: a 5-foot WNW swell with a light SSE cross-off wind, giving clean conditions and moderate energy. That’s more manageable for a good session.
Then the 26th of August is a beast. Tuesday morning and afternoon both deliver 10 feet of west swell with a 10-second period. The combined energy is massive – 1615 in the morning, 1833 in the afternoon. The wind is light and cross-shore, so the faces will be there. This is a big, powerful groundswell. For a beach break like Rossbeigh, that much size and energy will close out, so this is strictly for experts. The period is over 8 seconds but under 15, so it’s not that long-period wall, but the sheer power is intense.
To wrap it up: the best bet for most of us is Wednesday morning, the 12th of August, for a clean, beginner-friendly wave. For the brave, the last few days of the window – especially the 24th and 26th – offer serious, heavy swell, but you need to know what you’re doing.
Rusty.

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