The Lowdown
Alright, Rusty here, checkin’ in from the beach. Let's talk about Strandhill.
Right off the bat, I gotta be straight with you: the next week or so looks like a write-off for any sort of decent session. We’ve got a stretch of nothing but messy, wind-affected, or just flat conditions. The swell energy is tiny, mostly around 20 to 50 (weak energy), and the wind is all over the shop, mostly cross-onshore or onshore. There's simply nothing worth paddling out for most days.
Things start to look a little more interesting towards the end of the month. Hang in there.
The only real flicker of hope in this entire 16-day window arrives on Thursday the 27th of August, in the afternoon. That afternoon, we see the wind drop to glassy – absolutely still – and the swell bumps up a touch to 5ft from the west. That’s a rare moment of clean conditions at Strandhill, with the combined wave energy at a moderate 134. It’s a short-period swell at 7 seconds, so don’t expect any groundswell power, just fun, surfable waves when the wind is off. The water temperature is sitting at 62°, which is a touch warmer than normal for this time of year.
But it’s a brief window. The very next morning, Friday the 28th, the wind howls back in from the west at 22 mph, pushing in a raw, lumpy 8ft swell with a combined energy of 940. That’s strong energy, but the onshore wind is going to trash it. That size is also getting into the territory where it's too much for beginners.
Overall, Strandhill’s outlook is grim for the first nine days. The only standout is that one glassy afternoon on the 27th of August. Mark it in your calendar, but don’t hold your breath for much else. The forecast can always change, but right now, it’s looking pretty bleak for a decent paddle.
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.
