The Lowdown
Alright crew, Rusty here with the outlook for your local break.
Let me be blunt: this forecast is a tough pill to swallow for Strandhill. The water is sitting at 62°, which is a touch warmer than normal for this time of year, so at least you won't be freezing your tail off if you decide to paddle out.
The next few days are a total bust. From Sunday the 16th right through the rest of the week, it’s messy. We’ve got tiny, weak swell with energy levels in the double digits (37, 43, 70), and the wind is all over the shop—cross-off, cross, and cross-on—keeping the surface choppy. The swell is around 2 to 2 feet, and the period is short, so there’s no power or shape to work with.
We do see a spike on Wednesday the 19th morning, with a 10-foot swell from the west-northwest at an 11-second period. The combined energy jumps to 1796, which is a ton of power. But here’s the problem—it’s accompanied by a fresh 19 mph cross-shore wind, and the forecast itself says the swell is too big for this break. That’s expert-only stuff, and even then, the wind will make it lumpy and sloppy. The afternoon is even worse with a cross-onshore wind. This one’s a pass.
After that, we drop back into small, weak, and windy conditions through the end of the week and into the next. There’s a long gap of days with no real recommendations.
Finally, a glimmer of hope on Tuesday the 25th. The morning starts glassy with an offshore wind from the southwest, and the swell is 1 feet from the west-northwest at 10 seconds (energy 41). The afternoon cleans up nicely with glassy conditions and a 3-foot west-northwest swell at 10 seconds (energy 157). This is the standout window. It’s not big, but it’s clean and workable for an intermediate. The northwest swell direction is spot on for what Strandhill likes.
The following days are a mixed bag of small, clean conditions and some glassy windows, but the swell is tiny and inconsistent. We’ve got a few more mornings with clean, offshore winds on the 26th and 28th, but the swell is barely 2 feet.
So, the one true standout is Tuesday the 25th. Get your session in then. The rest of the 16-day window is a long, blank run of small, messy, or blown-out surf. It’s not unusual for the area, but it’s a rough one. Keep an eye on the forecasts, things can change.
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.
