The Lowdown

Alright, listen up. The first few days are a bit of a washout, but there’s some proper swell coming through the back half of the window that’s got some serious potential. You just gotta be patient.

Tuesday the 15th – forget it. Fresh cross-onshore winds, lumpy, short-period swell around 6 feet, and the energy is weak. Water temp is 60.3°F, which is a touch warmer than usual for this time of year. Not worth the paddle.

Wednesday the 16th stays poor. Choppy, cross-onshore, waves around 5-6 feet but with moderate energy. Nothing to write home about.

Thursday the 17th is when it gets heavy, but it’s messy. Swell jumps to 10-13 feet with strong cross-onshore winds. Energy is strong to very strong. This is not a day for the average surfer. Only the most experienced locals should even think about it, and even then, it’s going to be a grind.

Friday the 18th gives you a bit of a break. Swell drops to 8 feet, wind swings cross-offshore in the morning, making it clean. Energy is still strong. This is a day for the experienced crew only. The morning is your window before the afternoon gets a bit cross-shore.

Saturday the 19th – back to poor. Cross-onshore, choppy, 6-foot slop. Not worth your time.

Sunday the 20th is the turnaround. Light cross-offshore winds, clean, and a solid 6-foot W-NW swell with an 11-second period. Moderate energy. This is a proper surf day. Clean lines, good shape. The crowd might be out, but it’s worth it.

Monday the 21st keeps it clean. Light cross-offshores, 4-5 foot waves, moderate energy. Smaller, but still fun.

Now, Tuesday the 22nd – this is a standout. Light offshore winds, 6-foot swell with a long 16-second period, and strong energy. This is real groundswell, with serious push. The long period might make it wall up a bit at the beach breaks, but at Strandhill, this is going to be on. This is for experienced surfers only. Clean, powerful, and the wind is slight. This is the one to circle on the calendar.

Wednesday the 23rd stays excellent. Offshore winds, 6-7 foot swell, 13-second period, strong energy. Clean, lined up, and consistent. Another standout morning.

Thursday the 24th eases off. Waves drop to 4 feet, still offshore, but smaller. Weak energy. Good for a log, but nothing exciting.

Friday the 25th is a mixed bag. Morning has clean offshore conditions with 3-4 foot waves. The afternoon, though, the swell jumps to 8 feet with a very long 16-second period and strong energy. But tide and wind are questionable, so it’s marginal. If it lines up, could be epic, but it’s a gamble.

Saturday the 26th – another standout. Gentle offshore winds in the morning, 7-8 foot swell, 14-second period, strong energy. Big, clean, powerful. Only for experienced surfers. The afternoon has light rain and onshore winds, so get out early.

Sunday the 27th drops off. 4-5 foot waves, light offshore winds, clean but weak energy. Still surfable, just not thrilling.

Monday the 28th – the big one. Swell is predicted at 11-12 feet with an 11-second period, and energy is very strong. Offshore winds in the morning, going glassy in the afternoon. But here’s the thing: the swell is too big for this break. This is expert-only, and even then, it’s risky. The break might be closing out or just too menacing. If you’re not a charger, stay on the sand. This is for the camera, not the board.

Tuesday the 29th settles down to 7 feet with offshore winds, moderate-to-strong energy. Clean and good for experienced surfers.

Wednesday the 30th fades out. 4-5 foot waves with fresh offshore winds, but the period drops and energy is back to moderate. Clean, but the swell is fading. A mellow end to the window.

So, the standouts are Tuesday the 22nd, Wednesday the 23rd, and Saturday the 26th. That’s where the magic is. Monday the 28th is huge but dangerous, so give it a wide berth unless you

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.
