The Lowdown
Right, folks, Rusty here. Let's have a look at what's on the cards for Strandhill over the next couple of weeks.
Honestly, it's a bit of a tough stretch for the first week or so. We've got a run of small, weak swell and cross-onshore winds that just won't let up. The water is way warmer than it should be for this time of year, three degrees above normal, sitting at 64°F. That's very unusual.
From Saturday the 18th to through Thursday the 23rd, it's pretty much a write-off. Swell is tiny, between 1.0 ft and 2 ft, with short periods. The wave energy is weak, barely reaching 44. The wind is mostly cross-on or onshore, so the surf is going to be choppy and poor. You're looking at a solid week of flat, messy conditions.
Now, things start to get a bit more interesting around Friday the 24th of July. We see a jump in swell size, with the morning showing 4 ft from the WNW at a 10-second period. The energy picks up to 282 (moderate). But the wind is still cross-on, so it'll be lumpy. The afternoon gets bigger, up to 5 ft, but the wind picks up to 19 mph from the WNW, making it fresh and lumpy. It's still not great.
The weekend of the 25th and 26th holds some potential. The swell is there, 5 ft on Saturday morning and 5 ft in the afternoon, period around 9 seconds, with moderate energy (385 and 329). The wind is onshore, so it's not glassy, but it's not terrible. Sunday the 26th sees a drop back to 4 ft to 4 ft, and the wind is cross-on again. It's surfable, but nothing to write home about.
The real standout, the one that gets my blood pumping, is Tuesday the 28th of July. The morning is looking like a gem. The swell is a clean 3 ft from the WNW, with an 8-second period, and the wind is glassy from the east at just 3 mph. The energy is moderate (140). The report even says "surfable waves but very ordinary conditions" but with glassy wind, this is the best chance for clean, fun waves. The rest of the week drops back off, with small swell and cross-on breezes.
The very end of the forecast, on Friday the 31st of July, shows another glassy morning with a 2 ft swell from the west, but it's very weak energy (54). It's a possibility for a longboard, but not a standout.
So, to wrap it up: don't bother for the first week. The best bet is the morning of Tuesday the 28th of July. It's not a big swell, but the glassy wind will make it clean and fun. Keep an eye on that one.
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.
