The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s going on with the waves over the next couple of weeks.
We’re kicking off the forecast on Wednesday, the 12th of August, and honestly, it’s a slow start. The first few days are pretty grim. Wednesday morning at Strandhill sees a tiny 1ft swell from the WSW with a period of 10 seconds, but the combined swell energy is weak (34) and the conditions are poor. The wind is offshore, which is nice, but there’s just not enough push.
The situation doesn’t improve much through Thursday and Friday. Swell heights stay under 3ft, and the wind keeps switching around, often onshore, making it a write-off. We get a bit of a pick-me-up on Saturday morning, the 15th of August, with a knee-high 3ft swell from the WNW, but again, the wind is onshore and it’s messy. The energy is still moderate at best (107).
Honestly, the first real glimmer of hope comes on Sunday morning, the 16th of August. The swell drops back to 2ft, but the wind goes glassy. That’s a major positive. The waves are small and weak (40), but for a longboard or a foiler, that glassy window from the SW wind will be clean. It’s surfable, but you won’t be getting your wires crossed.
Then we hit a bit of a gap. Monday the 17th has a clean morning with 2ft, but the afternoon turns onshore again. The real deal looks to be shaping up on Tuesday, the 18th of August. The swell bumps up to 5ft from the W with a period of 8 seconds, giving us a solid moderate combined energy (334). The wind is cross-offshore from the S, keeping it clean. This is the best-looking session in the first week. The sets will be a bit short-period, but for a beach break like Strandhill, it should be a fun, pushy day for intermediates.
Things go a bit wild after that. Wednesday the 19th sees a big pulse of 12ft swell from the W, but the wind is howling onshore at 35 km/h. That’s a raw, blown-out mess. The energy is through the roof (2380), but it’s only for the experts, and even then, it looks like a washing machine. Thursday the 20th is still messy with onshore wind, and the swell is dropping.
The second week settles down, but it’s inconsistent. There’s a clean morning on Saturday the 22nd with a 3ft swell from the W and light cross-offshore wind, but it’s weak (97). The only other standout is the morning of Tuesday the 25th of August, which offers a clean 2ft NW swell with light offshore SSE wind. It’s a small wave, but clean.
If I had to pick the true standout, it’s the Tuesday morning, the 18th of August. That 5ft swell from the W with clean cross-offshore wind is your best bet for a proper session in the first week. The Sunday morning, the 16th of August is a close second for the glassy conditions, but it’s tiny. For the second week, the Tuesday morning, the 25th of August is the one to keep an eye on, but it’s a long-range call, so don’t book the day off work just yet.
Stay 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.
