The Lowdown
Right, folks, Rusty here. I’ve been staring at the charts for Strandhill, and it’s a tough one. The first real surfable window isn’t for a while, so don’t be in a rush.
The overall pattern is dominated by onshore winds, which is a real shame. There’s a persistent WNW swell, but the wind just keeps mucking it up. We’re looking at a gap of over a week with mostly poor conditions before we get a glimmer of hope.
The best bet on offer is the afternoon of Saturday the 5th of September. We’ll have a 5ft swell from the WNW, with a period of 10 seconds, and the combined wave energy is moderate (399). The big story here is the wind: the forecast is for glassy conditions, which is a massive positive. It’ll be clean and smooth. Just keep in mind, Strandhill is a beach/sandbar break, and it’s fairly consistent, but crowds are possible here.
The other standout is a bit of a wild card. The morning of Tuesday the 15th of September is flagged for a very big 10ft swell from the west with a period of 12 seconds, and the combined energy is strong (2468). The wind is cross-shore, which is messy. However, the forecast also says the swell is predicted to be too big for this break. This is only for experts, and even then, it’s a serious beast. The water temperature is a touch warmer than normal for this time of year, coming in at 62°.
For the first week, it’s a write-off. The WNW swell on Monday the 31st of August is 5ft but with a strong onshore wind of 15 mph, and a short period of 7 seconds. The energy is moderate (220), but the conditions are raw. The rest of that week is similar, with strong onshore winds and messy surf. The afternoon of Wednesday the 2nd of September has a clean, offshore wind, but the swell is tiny at 2ft and the energy is weak (57). It’s surfable, but only just.
The later part of the forecast, from the 14th of September, shows a big increase in swell size. The morning of Monday the 14th of September has a 8ft swell from the WNW with a very long period of 15 seconds, and strong energy (2424). The wind is cross-onshore, so it’s likely to be a beast. The morning of Tuesday the 15th of September is the biggest at 10ft, but it’s a mess.
That Saturday afternoon glass-off is the one to circle. The rest is a waiting game.
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.
