The Lowdown
Alright, let’s get into it. This is Rusty, and here’s how things are shaping up for Strandhill (County Sligo).
Right now, we’re looking at a pretty flat and messy start. There’s a small window of hope further down the line, but you’re going to need some patience. The first proper surfable day arrives on the morning of August 24th, so expect a solid gap of quiet, blown-out, or just tiny conditions before that.
The first highlight comes in on Monday, August 24th. Strandhill wakes up to a clean, lined-up WNW swell pushing through at a solid 4 ft. The period is a nice and juicy 11 seconds – that’s groundswell chatter, proper energy. The combined energy is sitting at a moderate 319 (moderate wave energy) and the wind is a light, clean cross-off from the SSE. This is the best of the bunch for the whole outlook – clean, with some push, and that offshore influence will keep the face smooth. Expect intermediate-friendly waves that could have some proper shape. The afternoon holds similar energy at 4 ft, and with the wind dropping to slight air, it could get glassy. Just be aware it can get a crowd here, especially when it’s good.
The water temperature is about average for this time of year, so nothing wild – just your typical cool Atlantic summer water.
After that, Tuesday through Thursday brings smaller, more ordinary waves. August 25th to August 27th offers waist-high surf with either light offshore or glassy conditions in the mornings. The wave energy is low, so it’s more of a longboard or foiling kind of vibe. Nothing to get excited about, but a few clean little runners on the sandbanks if you’re desperate.
Then we hit the weekend of August 30th through September 3rd, and things get interesting but ugly. A big pulse of swell rolls in late on August 30th, pushing 8 ft to 8 ft with a 12-second period and 1665 energy – that’s strong to very strong. But the problem? It’s blowing onshore or straight on from the NW and NNW at 12–19 mph, making it a total mess. This is one for the experts only, and even then, it’ll be a wind-battered battle. For most of us, it’s a skip.
The good news is we get another small clean-up on September 1st. Tuesday afternoon sees a light SSE cross-off, some clean little 3 ft waves from the WNW (9-second period), and just 123 energy. It’s small but clean – a last gasp of half-decent surf before the window closes.
Beyond that, a couple of days on September 2nd and 3rd are either tiny or pinned with fresh, choppy winds. Nothing to write home about.
For the kite crew: if you want to get out, the big windy and sloppy days around August 30th and 31st (onshore NW winds) might just be your playground, but for a surfer, it’s a write-off.
So to sum it up: your best shot is Monday, August 24th. Get on it then. After that, it’s clean but small, or big but blown out. That’s Strandhill for you – you take the good with the bad.
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.
