The Lowdown
Alright, folks, Rusty here. Let's have a look at what's on the cards for Strandhill over the next couple of weeks. Fair warning, it's a bit of a mixed bag, and we're in for a long wait before anything really gets going.
Right out of the gate, we've got a proper lull. For the first week, from Monday the 17th right through to Sunday the 23rd, there's almost nothing worth paddling out for. Some tiny, weak swell – down around 1ft to 2ft – with the combined wave energy barely ticking over, well under 100 for most of it, so it’s not even a whisper. The wind is all over the shop but mostly cross-on, making for choppy, poor conditions. It's a frustrating stretch.
The only real glimmer in that first week is late on Sunday the 23rd. The morning goes glassy with zero wind and a tiny 1ft WNW swell, but it's just not enough to ride. You'd be floating out there. It's a solid week of nothing.
The second week starts to show a little more life. Monday the 24th afternoon sees a spike in energy with a 5ft groundswell from the west, period a nice 11 seconds, and a moderate energy reading of 451. The wind goes cross-off, so it should be clean. The catch? The forecast calls it marginal, tide-dependent. Worth a look if you've got the patience.
We get a brief window on Tuesday the 25th morning with a clean, offshore breeze from the SSE blowing at 19 mph. But the swell drops right back to only 2ft, so it's more of a longboard or a session for the seals.
After that, it's back to choppy, onshore winds and small, ordinary surf until the end of the month. Not a lot to get excited about.
Then, hold onto your board. The standout by a mile is Tuesday the 1st of September. The models are firing up a serious swell. We're talking a 15ft swell from the WNW with a very long period of 13 seconds – that's proper groundswell, and the combined energy is massive at 6395. The wind is light and offshore or cross-off from the SSE/SE, so it’s going to be clean. That is an expert-only session, no doubt about it. The data flat out says the swell is predicted to be too big for this break, so if you're not a seasoned charger, stay on the sand and watch. The water temp is a touch warmer than normal for the time of year at 62°, which is nice.
So to wrap it up: a long, quiet first week, a few marginal but clean windows mid-to-late next week, and then a massive, expert-only bomb on the 1st of September. Keep your eyes on that last one.
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.
