The Lowdown
Alright, let’s talk about Strandhill.
For the first week or so, it’s mostly flat. The water’s at 62°F, which is a touch warmer than normal for this time of year, so that’s a small plus, but the surf is not.
From Friday the 31st of July through to the 7th of August, it’s a washout. The swell is tiny, under 3ft, and the wind is cross-on or onshore, making it chop city. The combined energy is weak, often under 100 (90), so there’s no power. There’s a brief moment on Sunday the 2nd of August morning where the wind goes light offshore from the SE, cleaning up the 2ft, 8-second swell from the WNW. The energy is still low at 46, but it’s the first time the surf becomes surfable. That afternoon, the wind goes glassy, but the swell drops to 2ft, so it’s really only for a longboard.
Things stay small and mostly poor until the 9th of August. That Sunday morning is the standout. The swell picks up to 3ft from the WNW, with a period of 7 seconds, and the wind is offshore from the SE. The energy jumps to 116, which is moderate. It’s clean, it’s got a bit of push, and it’s the best we’ll see. The afternoon swell gets a bit bigger at 5ft, with a longer period of 9 seconds, pushing the energy up to 322, but the wind shifts to a cross-offshore, and the forecast calls it marginal. The morning is the pick.
The 10th of August holds some similar, smaller surf with clean offshore winds, but the energy is back down. Past that, it fades out again into flat, poor conditions right through to the 15th of August. That Saturday morning sees a 4ft swell from the WNW, but the wind is onshore from the NW, which will ruin it. The energy is moderate at 104, but the onshore wind makes it unsurfable.
So, if you’re looking for a window, the 9th of August morning is the one to circle. It’s not a pumping swell, but it’s the cleanest and most surfable we’ve got. The rest of the time, you’re better off finding something else to do.

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.
