Kilcummin Harbour Surf Forecast and Surf Report

Right folks, Rusty here. It’s been a bit of a wait, but there’s some movement on the charts finally. Let’s break down what’s coming for Kilcummin Harbour.

We’re starting off the outlook with a real flat spell. The first few days are pretty grim. The swell is tiny and the wind is all wrong, leaving us with nothing worth paddling out for until Thursday the 3rd of September. Even then, it’s a marginal call with a 5ft swell from the West, but that 16 mph cross-off wind is just messing with the shape – not the clean surf we want. Thursday afternoon has a bit more size at 7ft from the WSW, but that 19 mph cross-off breeze and marginal conditions mean it’s still a slog.

Friday the 4th is a write-off. We get a massive 16ft groundswell from the WNW with a long 12-second period, so the energy is pumping – up at 7551 (moderate wave energy) – but the 25 mph cross-shore wind is absolutely ripping across the face, creating a complete mess. That’s kite-surfing territory, not paddle-surfing, for sure. The water temp is about average for the time of year, so no shock there.

Now, here’s where it gets interesting. Saturday the 5th is your best bet. The morning has a solid 8ft from the WNW, but the real winner is the afternoon. The swell drops a touch to 6ft from the WNW, the wind swings southerly and goes offshore at 9 mph. That’s the key – glassy, clean conditions. The energy is still there at 704 (moderate wave energy) and the waves are supposed to be very good. This is the standout session for the whole forecast. Get on it because the crowds can be _sometimes_ an issue, but with surf this clean and a decent 9-second period, it’ll be worth sharing a few.

Sunday the 6th could be okay if you’re desperate. The morning has a clean 5ft from the WSW with a fresh 19 mph offshore breeze, but the energy is weak at 399 and the conditions are still called marginal. The wind is just a bit strong for the size.

After that, things go a bit wild again. We get a couple of days of big, unruly swell and cross-shore winds from the 7th to the 9th. Monday the 7th has a 8ft+ swell and 22 mph cross-off wind – all chop. Tuesday the 8th is more of the same with lumpy 10ft waves. By Wednesday the 9th we’ve got a huge 12ft NW groundswell with a 12-second period (3413 energy – moderate wave energy), but the cross-onshore wind is just ruining it for us. This is a powerful, straight-breaking wave at a beach and reef set-up, so again, better suited for the kite crew than us paddlers.

The second week is quieter. Thursday the 10th sees the swell dropping to 8ft, but the cross-shore wind is still a factor. The best chance later on is Sunday the 13th. The morning has a clean 5ft from the WNW with a moderate offshore breeze. It’s not huge, the energy is only 467, but it’s clean. Then on Wednesday the 16th of September, we get a very interesting pulse. The morning has a 6ft groundswell from the WSW with a long, solid 11-second period. The wind is light cross-off at just 6 mph, making for clean conditions and a strong energy reading of 851 (moderate wave energy). That’s a promising, long-range highlight, but it’s two weeks out so take it with a grain of salt.

The final check on Thursday the 17th still has a clean 4ft from the WSW, but it's tapering off quickly. The gaps of poor surf from the 11th to the 15th are a real drag, but with good conditions on the 5th and a couple of other clean windows, it’s not all bad. Stay tuned.

Rusty.
