The Lowdown
Hey folks, it’s Rusty here. Let’s talk about the surfing outlook for Strandhill.
The forecast starts quiet, with no real surf for the first few days. There’s a gap with poor conditions until we get towards the end of the week. Honestly, the first half looks like a washout for paddling, though we do get a short window on Wednesday morning with small clean waves if you’re desperate for a splash. The real action doesn’t fire up until later.
The first standout is on Monday, September 15th. The morning at Strandhill (Sligo) sees a solid 7 ft groundswell rolling in from the west at a long 12 seconds, with gentle offshore winds from the SSE keeping things glassy. That’s proper clean surf right there. The combined energy is strong at 1175, so this is quality – but remember, at over 7 ft, it’s for experienced surfers only. The afternoon stays excellent with 7 ft clean conditions and a slightly lighter cross-off wind, still with heaps of energy.
The absolute standout of the whole 16-day window is Tuesday, September 16th. We’ve got an 8 ft swell from the WNW with a very long 13-second period – that’s serious groundswell. With S light winds at only 3 mph, the ocean will be a mirror. It’s a beast at 2486 combined energy, so expect powerful sets. This is strictly for good surfers; beginners should steer well clear. That long period means waves will hold up better at this beach/sandbar setup, but be ready for longer lulls between sets.
Throughout the rest of the second week, other days like Wednesday, September 9th offer size but are torn apart by strong cross-onshore winds. Those days are a hard miss. Monday, September 14th has a promising 5 ft swell with a 12-second period and light cross-off winds – it’s the only other morning with clean conditions before the big swells hit, but the crowd-factor is something to watch as it’s fairly consistent here.
Water temp is 62° F, which is a touch warmer than normal for this time of year, so you might not need the thickest wetsuit just yet.
Remember, the big swells in mid-September look great but it’s long-range, so keep an eye on forecasts.
Stay stoked,
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.
