The Lowdown

Alright, folks, Rusty here.

Right, we’re having a look at the next couple of weeks for Strandhill, and I’ve got to be straight with you—the start of this forecast is a real heartbreaker. We’ve got a gap of nearly two full days here with nothing worth paddling out for. It’s flat and choppy, with the wind all over the shop. The good news is, it doesn’t stay that way forever.

Let’s talk about the water temp. It’s sitting at 62°, which is a touch warmer than normal for this time of year—nothing crazy, but you might get away without the thickest wetsuit for a dawn session.

Monday the 24th of August is where things finally wake up. We’ve got a clean 4ft to 4ft swell rolling in from the WNW, and the wind is offshore from the SE. That’s a beautiful combo for Strandhill. The energy in the water is moderate, registering 313 in the morning, so there’s some proper punch behind it. This is your best bet in the first week—clean, lined-up waves with a bit of juice.

Now, if you can wait, the standout of the whole forecast is shaping up for Wednesday the 2nd of September. The swell jumps to 5ft in the morning with a solid period of 9 seconds from the W, and the wind is light offshore from the ESE. Light wind, clean conditions, and that chest-to-head high swell is going to peel nicely. The combined energy hits 353, so it’s got some real power. The afternoon gets a little bigger, pushing 8ft, but the period stretches right out to 12 seconds. That’s a long-period groundswell, and while it’ll have heaps of energy (1794), those long lines can sometimes close out a beach break. On the right tide, though, it’ll be a proper session for the experienced crew. Beginners, that afternoon might be a bit much.

Thursday the 27th of August offers a brief window of okay waves in the morning—2ft with a WNW swell and offshore wind—but it’s nothing to write home about. The rest of the first week is a mix of onshore wind and small, messy surf.

Into the second week, we get a few more clean, surfable windows, particularly Tuesday the 1st and Wednesday the 2nd of September, but nothing that lights the world on fire like that Monday the 24th.

So, my call: if you want the best of it, get on Monday the 24th of August or hold out for Wednesday the 2nd of September. That’s your window. Keep it salty.

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.
