The Lowdown
Right folks, Rusty here with a look at what’s on the cards for Strandhill over the next couple of weeks. To be straight with you, it’s a lean start and a long wait before we see anything worth getting properly excited about.
Looking at the whole picture, we’ve got a lot of small, messy, or onshore conditions for the first week and a half. Nothing really stands out until we get towards the back end of the period. There’s a solid pulse of swell building late in the second week, but the wind window is going to be the decider.
So, for the first few days here, it’s quiet. Monday the 10th has a tiny 2ft swell from the WNW, and while the wind is glassy, the wave energy is weak (61). It’s surfable but very ordinary. Tuesday the 11th through to the weekend is basically a write-off. The swell is small, the period is short, and the wind shifts around, mostly cross-off or cross-on, which isn’t doing us any favours. The energy readings are all low, mostly below 100.
The first real, albeit brief, glimmer appears on the morning of Thursday the 20th of August. We see a jump to 5ft from the WNW with a 10-second period, and the energy climbs into the strong zone at 509. It’s a little on the big side for beginners but manageable for intermediates. However, the wind is onshore from the NW, so it’s likely to be lumpy. The afternoon is similar, with 6ft (720 energy), but that onshore wind will spoil it for clean paddle surfing – might actually be better suited to a kite session.
Friday the 21st of August morning looks a bit more promising. The swell is 5ft from the W (449 energy) and the wind is a clean cross-off from the SSE. Could be a window for a session if you time it right, but by the afternoon the wind swings SW and picks up to 18 mph, turning it into a choppy, lumpy mess. Then Saturday the 22nd sees the biggest swell of the whole period, with 8ft waves from the WNW and an energy reading over 1200. That’s expert territory, and with a strong onshore wind, it’s going to be a washing machine.
Now, if you can wait, the real standout is on Tuesday the 25th of August. The morning brings a solid 7ft groundswell from the W (834 energy), with a clean cross-off wind from the south at just 3 mph. That’s a rare combo: proper size, decent period, and glassy conditions. The wave period is 10 seconds, so it’s got some power but should still hold shape. This is the one to circle. Afternoon stays at 7ft (898 energy), but the wind flicks onshore from the NW, so make sure you’re out early.
Remember, that Tuesday the 25th is a week and a half away, so keep an eye on the forecasts, but right now, that morning looks like the best we’ve got.
Stay stoked,
Rusty.

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