Kilcummin Harbour Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks at Kilcummin Harbour.

Right out of the gate, we’ve got a bit of a slow start. The first real chance to get wet doesn’t come until Monday morning, September 14th. It’s nothing huge, but it’s clean. A solid 4 ft swell from the W with a moderate offshore breeze from the S, so the face will be smooth. The water is sitting at 60°, which is a touch warmer than usual for this time of year—nothing crazy, but you’ll notice it. The combined energy is weak at best (255), so it’s more of a longboard or funboard session. Don't expect much push.

Monday afternoon picks up a notch. The swell bumps to 5 ft, still from the W, but the period jumps to 11 seconds, which brings proper groundswell energy (619). The wind holds offshore from the SSW, and the sets will have a bit more shape. It’s a good afternoon for an intermediate surfer to get some clean rides.

Tuesday morning, September 15th, is where things get a bit meaty. Swell hits 8 ft from the W, but the wind swings to a cross-shore from the WNW at 19 mph, and it’s lumpy. The combined energy is strong (1146), but the chop makes it a wrestle. This one’s more for the experienced crew who don’t mind a bumpy surface. Tuesday afternoon is similar, cross-onshore, poor conditions—best left alone.

Wednesday September 16th stays big with 8 ft swell, still from the WNW, and the wind is cross-shore again. The energy is pumping (1381), but the quality is marginal. The afternoon cleans up a bit with a cross-off breeze, but it’s still lumpy.

Thursday September 17th is the big one for the first week, but it’s for experts only. The morning sees 13 ft of WNW swell with a 22 mph cross-wind and energy readings through the roof (3368). By afternoon, it jumps to 18 ft with a 14-second period (11312) and cross-shore wind. That is massive, raw, and dangerous. This is a day for the kamikaze crew, and even then, it’s not clean.

Friday September 18th settles down a bit. Morning brings 13 ft from the WNW but with a moderate offshore from the SSW, making it clean and powerful. Combined energy is still very strong (5133). This is the standout of the first week for experienced surfers. The afternoon stays solid with 12 ft and a cross-off breeze, but the wind picks up.

The weekend (September 19-20) offers up consistent 10 ft WNW swell with moderate energy (1605-2521). Saturday is clean in the morning with a cross-off breeze. Sunday morning is the real highlight of the weekend: 10 ft, 12-second period, offshore from the S, and the report calls it excellent for experienced surfers. That’s your window.

Moving into the second week, Monday September 21st brings a drop to 6 ft from the W, offshore wind, clean, and moderate energy (879). Nice easy session. Tuesday the 22nd is smaller again at 4 ft, offshore in the morning, but the afternoon gets messy with a cross-on wind.

Wednesday September 23rd is a sleeper pick. Morning is 6 ft from the WSW, clean, offshore from the S, and combined energy is moderate (808). The afternoon sees 7 ft from the W, clean with a cross-off breeze, and the report says it’s excellent for experienced surfers. That’s a solid afternoon.

Thursday September 24th is another cracker. Morning has 8 ft from the WNW, gentle offshore, clean, with strong energy (1674). This is a standout for the second week. The afternoon holds at 8 ft, still clean. If you can get out in the morning, do it.

Friday September 25th is all about the glass. Wind is near zero from the NNE and ENE in the morning and afternoon. The swell is modest at 5 ft from the WNW and W, with low energy (401-447). It’s glassy perfection for a longboard or a mid-length.

Saturday September 26th offers 5 ft from the N in the morning with an offshore breeze, clean. Afternoon gets a bit cross-on, so morning is the call.

Sunday September 27th sees a bump to 8 ft from the N, but the wind is cross-shore and the period is short at 8 seconds. It’s lumpy and weak for the size. Not worth the paddle.

Monday and Tuesday (September 28-29) drop off hard. Swell under 3 ft, weak energy, and cross-off winds. The 29th does show a 5 ft W swell with a 14-second period (1049), but it’s listed as marginal. A possibility, but not a priority.

So, if I’m calling the standout: Friday September 18th morning for the big, clean, powerful WNW swell for the experienced crew, and Thursday September 24th morning for the second week, when it’s 8 ft, clean, and glassy. Get on it.

Rusty.
