The Lowdown
Alright folks, Rusty here. Let’s get straight into it for Strandhill.
Honestly, I’m looking at a pretty bleak 16-day window for us. The water is sitting at 62°F, which is a touch warmer than normal for this time of year, but that’s about the only bit of good news.
We’ve got a handful of days with surfable waves, but they’re all rated as “very ordinary conditions.” The opening stretch from Friday the 14th through to Monday the 17th is a write-off – tiny waves, poor surf. We’re talking swell heights stuck around 2ft to 3ft, weak energy (between 49 and 84), with short 7 to 8 second periods, and mostly onshore or cross-offshore wind. Not worth suiting up.
Then there’s a big gap. Tuesday the 18th and Wednesday the 19th see a spike in swell – up to 7ft – but it’s blown-out. The wind is howling from the west at 16 to 25 mph, cross-onshore, making it a lumpy, choppy mess. The combined energy jumps to 606 and even 1104, but with conditions like that, it’s more of a kite-surfing show than a clean surf session. Even for the crew, that’s not what we’re after.
The energy drops again from Friday the 21st through the weekend, with more tiny, weak swells and cross-onshore winds. Not a single standout in that block.
There’s a glimmer late in the period. On Monday the 24th, we get clean offshore winds from the SSE, but the swell is only 0.7ft to 2ft. Tuesday the 25th picks up to 3ft from the west with a 12-second period (moderate energy of 214), but the wind is cross-onshore, so it’s still not great. The most promising stretch is Wednesday the 26th and Thursday the 27th. On the 26th, we’ve got 3ft to 3ft swell from the west, gentle offshore winds from the ESE and SE, and clean conditions. Energy is moderate at 145 to 171. Then Thursday the 27th brings glassy conditions in the afternoon with 3ft swell from the west. That’s about as good as it gets, but it’s still small and ordinary.
The rest of the forecast into the end of August is more of the same – tiny, weak, and unremarkable. There are no real standouts. The best I can honestly say is that if you’re desperate, Wednesday the 26th and Thursday the 27th offer the cleanest windows, but don’t expect much.
Rusty, signing off.

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.
