Kilcummin Harbour Surf Forecast and Surf Report

Alright folks, Rusty here. Let's chew the fat on what's brewing.

First off, the water is 62°, which is a touch warmer than usual for this time of year – a nice little bonus for the session.

We're looking at a bit of a mixed bag to start with. The first solid call is for Saturday afternoon, September 5th. Kilcummin Harbour is seeing a clean 6ft swell from the WNW with a period of 10 seconds. The wind is a gentle offshore from the SSE, making for some tidy conditions. The combined swell energy is sitting at a solid 707 (moderate wave energy), and while the crowd can be there sometimes, it'll be worth it. This is a decent opener.

The weekend has a bit of a downer. Sunday morning on the 6th is a write-off with a fresh onshore breeze ruining things, but Sunday afternoon sees a spike to 7ft from the WSW with a moderate cross-off breeze. The energy jumps to 894 (moderate), but the quality is marginal. Monday the 7th is much the same story: a building 8ft to 10ft from the W, but strong cross-off winds keep it from being truly clean. The energy is ramping up (1213 and then 1816 – strong), but the conditions are keeping the quality down.

Then we hit a proper wall. Tuesday the 8th is a full-on mess. We’ve got a raw 15ft from the WNW, with a combined energy of 4950 (very strong). That's serious size, but it’s blowing a strong cross-shore and cross-onshore gale. The quality is poor, and this is strictly for experts only – and even then, only if you’re keen on a beatdown. Honestly, with that wind and size, this setup looks more interesting for kite surfing than paddle surfing.

Things settle down a bit by Wednesday morning the 9th with a cross-shore 6ft, but it’s not until Wednesday afternoon that we get a proper clean window: 5ft from the WNW with a gentle cross-off wind and a combined energy of 514 (moderate). That’s a nice, clean little session.

Thursday the 10th and Friday the 11th are a bit average, with clean but small conditions on Thursday, and then a messy cross-shore on Friday spoiling a 7ft swell.

Now, the standout. While the second week has some fun windows, the absolute best on offer is Sunday, September 14th. Monday morning the 14th. We’ve got a pumping 10ft groundswell from the WNW with a very long period of 12 seconds. The combined energy is 2730 (very strong). And the wind? It’s a gentle offshore from the SW. This is big, powerful, and clean. This is for experienced surfers only. But for the right crew, it’s the call of the fortnight.

The run after that holds some promise. The mornings of September 17th and 18th are looking excellent. Thursday the 17th has a strong 12ft WNW swell with glassy conditions and a combined energy of 2980 (very strong). That is a serious, clean groundswell for experts. Friday the 18th stays clean with a 8ft to 8ft W swell, and that run continues through the weekend with clean offshore winds and 7ft+ swell from the WNW through to the 20th. The Thursday and Friday of the second week are the real highlights if you can time it right.

So to sum it up: the first week is patchy with a huge, windy storm in the middle, but the second week, particularly around the 14th and then the 17th and 18th, is where the magic is. The long-range stuff is promising but keep an eye on it.

Rusty.
