Kilcummin Harbour Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what’s shaping up for Kilcummin Harbour over the next couple of weeks.

First up, the water temperature is sitting about average for this time of year, so nothing wild there. The outlook starts off a bit meh, but there’s a couple of days that are definitely worth circling on your calendar.

We kick off on Monday the 10th of August with a morning session that’s actually alright. We’ve got a 3ft swell out of the NW with a period of 8 seconds, and the wind is glassy – dead calm from the SSW. Combined swell energy is around 209 (moderate energy), and it's clean. Conditions are good for a paddle, though not huge. Afternoon turns a bit average with cross-shore wind and questionable tide.

Tuesday the 11th and Wednesday the 12th are pretty poor. Swell drops back, and although we get offshore winds, the wave size is small (2ft to 3ft) and the energy is low (around 137-147). Ordinary, to be honest.

Now, Thursday the 13th morning is a step up. A 4ft swell from the WSW, 10-second period, with a moderate offshore breeze from the S. Combined energy hits 256 (moderate). It’s clean, and conditions are good. This is probably the pick of the first week.

From Friday the 14th through to Tuesday the 18th, honestly, it’s mostly poor to marginal. Swell hangs around, but wind is cross, cross-on, or choppy, so it's messy. You’ll see a few waves, but nothing special.

But here’s the standout: Wednesday the 19th of August, morning session. This is the one. Swell bumps up to 7ft from the WNW with a period of 11 seconds. The wind is glassy – absolutely dead from the N. Combined swell energy is 1192 (strong energy). That's a lot of power behind those waves. This is expert territory; 7ft is for the experienced crew. For a reef break like Kilcummin Harbour, that long-period groundswell will wrap in nicely and produce some proper, clean lines. Crowds can be around sometimes, but with that size, you might have it more to yourself – though it’ll be a heavy paddle out.

After that, from Thursday the 20th right through to Tuesday the 25th, it dries up again. Wind turns onshore or cross-onshore, swell drops, and the scores go to zero. A long stretch of poor conditions there.

So, bottom line: the first 10 days are mostly patchy, with Thursday 13th morning being a decent, clean option. The absolute highlight is Wednesday 19th morning – big, clean, glassy, but strictly for the experienced. The later part of the window is a write-off.
