The Lowdown
Right, grab a cuppa and settle in, because the next couple of weeks at Strandhill are a proper mixed bag. We’ve got a big blank spell to start, then a few glimmers, before the ocean loses its mind again. Let's get into it.
The first half of the 16-day window is a write-off, mate. A solid 5 days of poor conditions kick things off. Monday afternoon stays cloudy with a cross-on W wind at 9 mph pushing into a weak 3 ft swell from the west. The water's a touch warmer than normal at 62°, but that’s small comfort. Tuesday and Wednesday are just as grim with howling winds and no shape. We finally get a change on Wednesday 2nd September morning – a light SE offshore breeze at 9 mph cleans up a tiny 2 ft W swell. The energy is weak (57), but it’s the first clean surf we’ve seen. It’s surfable, but very ordinary. Still, that offshore wind is a major positive for the morning session.
The next real standout, and the best call of the whole run, is Saturday 5th September. This is the one. Early morning, we’ve got a 5 ft swell from the WNW, with a moderate 11-second period pushing in. The combined energy is moderate (521). The wind is a sweet, gentle SSE offshore at 9 mph, setting up clean, lined-up waves. This is where Strandhill (Sligo) shows its class. Expect very good conditions, and while it’s fairly consistent, be aware the crowds can turn up on a weekend when it’s this good. A fantastic window for intermediate surfers.
The afternoon on Saturday 5th holds up too, with a clean offshore wind still blowing, though the swell drops to 4 ft. Sunday 6th morning is small and clean, but the energy’s gone by then.
The second week gets messy. Monday 8th sees a fresh offshore SSE wind at 22 mph and a 6 ft swell from the W, but the wave comment is marginal, so it’s not a clean call. Wednesday 9th is a monster – we’re talking a 13 ft W swell with a 12-second period, and a combined energy reading of 4668 – that’s strong to very strong. But the wind is a near gale from the SW, making it a total mess. This is a beach/sandbar break, so with that much power and wind, it’s going to be a washing machine. Only for the most experienced, and honestly, it’s gonna be more appealing for the kite crew than a paddle.
The last few days of the run are tiny and clean, with glassy conditions on the 15th, but the swell is barely 0.7 ft. Not worth the rubber.
So, the best on offer is absolutely Saturday 5th September morning. Get on it. The rest of the fortnight is either flat, blown out, or too challenging for the average surfer.

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.
