The Lowdown

Alright, folks, Rusty here. Let’s have a look at what’s cooking for Strandhill over the next couple of weeks.

Right off the bat, I gotta be straight with you: the next few days are a right-off. We’ve got a real flat spell on our hands. From Thursday the 20th right through to Sunday the 23rd, it’s just tiny, messy, cross-on junk. Winds are howling out of the north, keeping things choppy and lumpy, and swell heights are barely ticking over 1 ft to 3 ft. The water is a touch warmer than normal for this time of year at 62°, which is a nice detail, but it's not enough to get you in the water. Even the glassy moments on Sunday morning and afternoon with barely a ripple are on swells so small (0.7 ft to 1.0 ft) there’s nothing to ride.

Okay, now we’re talking. The first real glimmer of hope comes on Monday, the 24th of August. We get a shift in the wind to a gentle offshore from the southeast, and that’s going to clean things right up. The swell bumps up to 4 ft out of the WNW with a period of 11 seconds—that’s proper groundswell. The combined energy reads 308 (moderate), and with those offshore winds, you’re looking at clean, lined-up waves. Monday afternoon holds at 3 ft. This is your standout window for the whole forecast. The break is a beach/sandbar set-up, so that long period might make it a bit straight, but with the wind on it, I’d be out there.

After Monday, things get a bit ordinary again. Tuesday the 25th sees the swell drop right back to 2 ft, and the wind goes cross-off from the ESE, so it’s clean but tiny. Wednesday and Thursday are similar—clean but small, with the odd window of glassy conditions on Thursday morning the 27th, but the swell is only 2 ft. It’s better than the first few days, but nothing to get excited about.

Then we get a bit of a pulse late in the run. The end of August and start of September sees some bigger, more powerful swell, but the wind is all wrong. From the 28th onwards, we’ve got onshore and cross-on winds from the WNW and NW, ruining the shape. The swell gets serious—on the 29th of August, we’re looking at 5 ft and the combined energy hits 413 (strong), and by the 4th of September, it’s pushing 7 ft with a 12-second period and a massive energy reading of 1357. That’s a lot of power, but it’s all blown out. The wind is howling onshore at 12-15 mph, making it a choppy, lumpy mess. That’s more of a kite-surfing scenario than a paddle-surfing one, to be honest.

To sum it up: the first few days are a total dud, then Monday the 24th of August is your absolute best bet with clean 4 ft groundswell and glassy offshore winds. After that, it’s mostly small or messy, with a big, powerful swell at the end that’s unfortunately blown out. If you only get one session, make it that Monday.

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.
