The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the pipe for the next couple of weeks.
Honestly, I’m looking at a pretty grim stretch here. For the first week, from Monday the 17th of August through to Sunday the 24th, it’s a write-off. The swell is small and weak, and the wind is mostly cross-onshore, making it choppy and messy. There’s no real surf on offer at all for a solid 8 days. It’s a tough run, but that’s the way it goes sometimes.
The first real chance of a wave comes on Tuesday the 25th of August at Strandhill. We’re looking at a modest 4ft to 4ft swell from the west, with a period around 10 seconds. The wind will be offshore, keeping things clean. The combined energy is moderate (260), and the water temp is sitting at 62°, which is a touch warmer than normal for this time of year. The catch? It’s only a marginal surf forecast, so don’t go expecting perfection. It’s the best on offer, but it’s not a standout.
The real standout, and the one I’d be circling on the calendar, is Tuesday the 1st of September. That morning we’ve got a solid 6ft swell from the west-northwest with a very long period of 14 seconds. That’s a groundswell with serious energy (1223). The wind is a light cross-offshore, which will keep the faces clean. A long-period swell like this can be a bit straight at a beach break, but Strandhill can handle it if you know where to sit. The difficulty is intermediate, so if you’re a beginner, that 6ft might be a bit much. The crowds are sometimes, so expect a few heads out. The afternoon brings a strong offshore breeze at 25 mph, which will clean it up, but that’s going to be a paddle battle. This is the one to aim for, but it’s over a week away, so keep an eye on the forecasts.

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.
