Kilcummin Harbour Surf Forecast and Surf Report

Alright crew, Rusty here, breaking down the outlook for Kilcummin Harbour in the units you landlubbers might be more familiar with.

We’ve got a real mixed bag over the next two weeks. The early part is a bit of a washout for clean waves thanks to strong wind. The real standout, and you’ll want to mark this one, is the session on Saturday, 12th September. That’s the one.

Water temp is sitting at about 62°, which is a touch warmer than normal for this time of year.

Saturday the 5th kicks off with some okay surf. Morning has about 8ft of swell from the WNW at 10 seconds, with a solid 1237 (moderate to strong) combined energy. The wind is cross-off, so it’s clean, but it’s a bit marginal. The afternoon drops to 7ft from the same direction, but the wind turns offshore and light, cleaning it right up. That afternoon window is a decent little session.

Sunday the 6th? Forget it. Wind is howling at 22 mph offshore in the morning with a weak 4ft swell, and by the afternoon, the swell is gone. Monday the 7th sees a big jump in size, 10ft in the morning and 13ft in the afternoon, but the wind is cross-off and strong (22–25 mph), making it a messy, lumpy affair. Tuesday the 8th is even bigger, with 16ft of WNW swell, but the wind is cross-shore and strong, creating a lumpy cross-chop. That’s expert-only, and even then, it won’t be pretty.

Wednesday the 9th through Friday the 11th is a lot of cross-shore and cross-off wind, with lumpy conditions and dropping swell. Nothing to get excited about.

Now, the one. Saturday, 12th September. The morning session is your best bet. You’ve got 8ft of WNW swell at 11 seconds, a solid 1253 (moderate to strong) combined energy. The wind is offshore from the south at 16 mph, keeping it moderate but clean. The guidance says this is excellent surf for experienced surfers. The optimum swell direction is NNW, and this is WNW, so not a dead-set match, but close enough. For a reef break that’s fairly consistent, this is a proper window. The afternoon gets messy, so make the most of the morning.

After that, Sunday the 13th and Monday the 14th are small and weak. Tuesday the 15th is a write-off. Wednesday the 16th and Thursday the 17th are blown out with onshore wind. Friday the 18th is also onshore.

Then we get another promising window at the very end. Saturday, 19th September, morning session has 6ft of WNW swell, clean with a light cross-off breeze. The energy is lower at 603 (moderate), but it’s clean. Sunday, 20th September, morning is also looking good: 6ft of WNW swell at 11 seconds, with a light offshore wind from the south making it glassy. Both of these are late in the forecast, so less certain, but they’re promising.

Overall, the standout is the morning of Saturday, 12th September. After that, keep an eye on the 19th and 20th.

Rusty.
