The Lowdown
Right then, let’s have a proper look at what’s brewing for Strandhill over the next couple of weeks. I’ll be straight with you – the start of this run is a bit of a write-off, so don’t bother waxing up just yet.
We’ve got a long dry spell to kick things off. From Monday the 7th right through to the end of Thursday the 10th, it’s a total mess. Rain, cross-shore winds, and lumpy, poor surf. The energy is there on Monday the 7th – a combined energy of 444 (moderate) – but it’s all ruined by a 12 mph cross-shore wind. The swell is 5 ft at 9 seconds from the west, but it’s just not clean. Tuesday the 8th sees a jump in size to 8 ft, but that’s accompanied by a stiff 25 mph onshore wind, making it a total churn for experts only and even then, you’d be mad. Thursday the 10th cleans up a bit with a cross-offshore breeze, but the swell drops to a weak 3 ft, and the scores are still poor. It’s a frustrating wait.
Finally, we get a little glimmer on Friday the 11th afternoon. The wave comment says “marginal,” but it’s the first hint of life. The swell is 5 ft from the west-northwest at 9 seconds, with a light 6 mph cross-on breeze. The combined energy is 412 (moderate). It’s not great, but it’s better than the nothing we’ve had.
Now, the real window opens up on Saturday the 12th. This is the first proper standout. The morning shows a 7 ft swell from the west-northwest with a very long period of 14 seconds – that’s proper groundswell energy. The combined energy is a hefty 1419 (strong). The wind is a clean cross-offshore from the south at 19 mph. The wave comment says “marginal,” but the conditions are clean. This is a bigger swell, at 7 ft, which is getting into the “not for beginners” territory, but it’s a long-period groundswell that will really wrap into Strandhill’s sandbar. The crowd profile here is “sometimes,” so you might have some company, but it’s worth it.
The next true standout is Thursday the 17th. The afternoon session is the absolute cream of the crop. You’ve got a 8 ft swell from the west, with a period of 11 seconds, and a clean, moderate offshore breeze from the southeast at 12 mph. The combined energy is a beefy 1348 (strong). The wave comment says “excellent surf conditions for experienced surfers.” This is the one. The swell is over 7 ft, so it’s for the experienced crew, but the offshore wind will groom it to perfection. The water temperature is 61°, which is a touch warmer than normal for this time of year, so you’ll be alright in a spring suit.
The following Friday the 18th is also a brute. The morning sees a 8 ft swell from the west at 12 seconds, with a moderate offshore breeze from the southeast at 16 mph. The combined energy is a massive 2310 (very strong). The comment says “marginal” for the morning, but the afternoon is rated “excellent” again with a 8 ft swell from the west-northwest at 12 seconds and the same clean offshore wind. This is big, powerful stuff – only for experts.
After that, the swell drops a little but stays surfable. Saturday the 19th and Sunday the 20th have clean conditions and solid 6 ft to 8 ft waves, but the wind shifts to cross-offshore, which is still fine. The best of the run is Thursday the 17th afternoon and Friday the 18th afternoon. Mark those in your calendar.
So, to wrap it up: the first week is a washout. Don’t bother. The pick of the whole period is Thursday the 17th and Friday the 18th, with solid, clean, offshore surf. Get on it.

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.
