The Lowdown
Alright folks, Rusty here. Let's have a look at what's going on with Strandhill. It's a bit of a mixed bag ahead, so settle in.
The good news is we’ve got a few windows of proper surf, but you’ll need to be patient because there’s a whole lot of flat and slop to wade through first. The first real sniff of something rideable doesn't show up until Monday the 24th. Up until then, it’s a write-off with tiny, weak waves. Sunday the 23rd is a complete dud with barely a ripple—just a glassy pond with 0.7ft to 1ft of nothingness.
Monday the 24th is where it starts to get interesting. We get a pulse of groundswell from the WNW pushing in at 3ft to 4ft with a solid 11-second period. The energy is moderate (254-270), but the wind is light offshore from the SE, keeping it glassy and clean. This is the standout session of the first week. It’s a proper sandbar setup, fairly consistent, and with light offshore breezes, it'll be peeling nicely. Expect some company though, as it can get crowded here.
Tuesday the 25th holds some surfable waves (3ft) but the wind swings more easterly and picks up, making it a bit bumpy. By Wednesday and Thursday, we’re back down to tiny, weak junk, and the wind goes onshore from the north-west by Friday the 28th through the weekend, which is a complete write-off. That stretch from the 26th to the 1st of September is a long, flat, wind-affected hole. A few small pulses try to show but the onshores ruin them.
Now, looking further out, things get promising again. Wednesday the 2nd of September sees a big improvement. The afternoon brings a solid 6ft swell from the W with a 9-second period, and the combined energy jumps to a strong 548. With light cross-offshore winds, it's looking clean and punchy. But the real standout of the entire 16-day window looks to be Thursday the 3rd of September. We get a bigger WNW swell at 7ft, a strong 739 energy reading, and clean, moderate offshore winds from the SSE. The period is a touch short at 9 seconds, so it won't be a drawn-out groundswell, but it’ll be powerful and lined up. At that size, it’s getting into expert territory, but the offshore wind will make it a gem.
There’s also a sneaky mention of Sunday the 6th of September with a 4ft swell from the NW and light offshore winds again—another clean option, though the period drops to 8 seconds, making it a bit more disorganized on the sandbar.
The water temperature is sitting about average for this time of year off Strandhill, so no surprises there.
Stay patient for the first few days, get out on Monday the 24th for the cleanest early session, and circle Thursday the 3rd of September on your calendar—that’s the one with the most grunt and the cleanest windows.
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.
