The Lowdown

Alright, surfers, Rusty here. Let's take a look at what Mother Nature has in store for us at Strandhill over the next couple of weeks.

Right off the bat, it's a bit of a slow start. For the first few days, the swell is tiny and the wind is mostly messy. We've got a bit of a wait on our hands before anything really gets going. The water temp is sitting pretty average for this time of year, so no surprises there.

Thursday the 13th is a no-go. We've got a weak 2ft swell from the west with a mediocre 10-second period, but the cross-offshore wind is just making things ordinary. The combined energy is weak (100), and it's just not worth getting wet. The next few days are much of the same: Friday and Saturday see onshore winds and small, weak swell, with the combined energy dropping into the double digits. It's a tough stretch.

We finally get a little glimmer of hope on Sunday the 16th morning. The wind goes glassy, and the swell is a tiny 2ft from the WNW. The combined energy is only 39, so it's not going to be epic, but it will be clean. A good morning for a longboard and a paddle if you're desperate.

Monday the 17th and Tuesday the 18th are not worth the drive. The swell is still small, and the wind is all over the place. Stay home.

Now, here's where it gets interesting, but also a little dangerous. On Wednesday the 19th, the ocean wakes up. A big 8ft to 10ft swell from the west-northwest rolls in with a solid 11-second period. The combined energy jumps to a massive 1612, which is seriously strong. But here's the kicker: the wind is blowing strong onshore at 19 mph. This is a classic case of "it's big, but it's ugly." The conditions are going to be blown out and messy. This is expert-only territory, and honestly, with that onshore wind, it might be more fun for the kite surfers than us paddle surfers. The swell direction (WNW) is a perfect match for the optimum, but the wind is just ruining it.

The size drops off a bit on Thursday the 20th, but it's still onshore and choppy. Not great.

We get another small window on Friday the 21st morning. Glassy conditions and a tiny 2ft WNW swell. The combined energy is only 47. It's not a standout, but it's clean. A similar situation happens on Saturday the 22nd morning, with a light offshore wind and a 1ft swell from the west. The period is a very long 11 seconds, which means it's a proper groundswell, but it's just too small to do much with at a beach break like Strandhill.

Looking further out, the second week is slim pickings. There are a few mornings with light offshore or glassy winds on the 23rd and 26th, but the swell is consistently below 2ft and the combined energy is weak. It's the kind of setup where you might find a knee-high wave if you're lucky, but there's nothing to get excited about. The forecast is less certain this far out, but it's looking like a flat spell.

So, the honest truth? There's no true standout session in this 16-day window. The best you can hope for is a clean, tiny wave on a glassy morning. The big swell on the 19th is there, but it's going to be a blown-out mess. Keep your eyes on the forecasts, because things can change, but for now, don't be afraid to take a break.

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.
