The Lowdown
Straight up, it's rough out at Strandhill for the next few days. Tuesday's got a fresh cross-onshore breeze whipping up a lumpy 1.9m of short-period slop. Forget it. Wednesday's the same story, just a bit choppy. And Thursday? We're looking at a big, messy 3.5m swell with a strong cross-onshore wind. That's a full-on washing machine, with energy off the charts over 4776. Not your day unless you're a masochist.
Finally, on Friday the 18th, the wind swings cross-off and the swell settles to a clean 2.5m. It's still a bit questionable, but it's the first proper window we've had. Saturday's got a similar vibe – clean 2.1m with a cross-off breeze. It's surfable, but not perfect.
The start of next week, Sunday and Monday, sees the swell drop to 1.5m and the wind go light. It's clean but small. There’s a tiny pulse on Tuesday the 22nd, but it doesn't amount to much.
Now for the main event: Wednesday the 23rd. This is the standout. A light offshore breeze, a solid 2.5m of west-northwest groundswell with a 13-second period, and the energy is pumping at 2376. It's calling for excellent conditions for experienced surfers. This is the one to circle on the calendar. That long period will have some punch, and the offshore wind will make it proper. It might be a bit too raw for beginners, but for anyone with some experience, it's going to be firing.
After that, it fades fast. Thursday and Friday are messy again. The weekend is tiny, with 0.9m dribble on Saturday. But hold on, Tuesday the 29th has one more trick. The swell builds back to a clean 1.2m, with a 12-second period and a gentle offshore wind. It's not big, but it's clean, and after all that blown-out crap, clean is a blessing. That's your other best bet.
So, the long and short of it: the next week is mostly a write-off. But that Wednesday the 23rd is a proper day for the experienced crew, and the 29th is a great option for a cleaner, smaller session. Keep an eye on the wind. It's the whole ballgame out there.

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.
