The Lowdown

Alright folks, Rusty here with a look at what's on offer for the next couple of weeks. We're looking at a bit of a dry spell at the start, but don't lose hope.

We've got a good stretch of nothing burger coming up. From Wednesday the 29th of July right the way through Saturday the 9th of August the surf is pretty much a write-off. Either it's too small, the wind is blowing the wrong way, or the swell's just not got any power. A few days, like Friday the 7th of August morning, have a little bump of 5 ft from the west, but with a pitiful 7-second period and cross-onshore wind, it's just a messy, choppy washout. The wave energy out there sits around a weak 74 to 306 (moderate energy at best, but terrible conditions).

The real action, and the only real standout of the entire outlook, will be on Monday the 10th of August and Tuesday the 11th of August. Monday the 10th of August afternoon is where we finally see some life. Kilcummin Harbour (Kilcummin-Harbour) has a solid 6 ft swell rolling in from the WNW with a 9-second period. That's a decent combo, and the winds are set to be light and clean, a sweet cross-offshore. There's a moderate 553 (strong energy) in the water. It's still a reef break, so mind the bottom, but the conditions will be clean. Tuesday the 11th of August is even better for consistency. The morning brings a clean 6 ft from the NW with light offshore winds from the south; again, that's clean. The wave energy is strong at 449. The afternoon holds a slightly smaller 5 ft set, but still clean. For a spot that's only "fairly consistent," this is a great window to hit.

After that little taste of fun, things dry right up again for the rest of the outlook. The swell sticks around but the wind turns onshore or cross-shore, completely spoiling the party. Wednesday the 12th of August morning is surfable but ordinary, and from there it's back to the poor conditions.

So, to sum it up: sit tight through a long, flat week. The best bet, and really the only bet worth making, is the afternoon of Monday the 10th and all day Tuesday the 11th of August at Kilcummin Harbour. Get out there and enjoy it while the clean winds are on it. The rest of the forecast is a dud. Keep an eye on the charts, though, they can always change.

Rusty.

Information about the Kilcummin Harbour Surf forecast

The above surf forecast table for Kilcummin Harbour provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kilcummin Harbour can be found by selecting the local surf guide option on the grey menu. Our Kilcummin Harbour 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 (Kilcummin Harbour) 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 Kilcummin Harbour 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.
