Kilcummin Harbour Surf Forecast and Surf Report

Alright, grab yer board and let’s have a look at what’s on the cards for Kilcummin Harbour. It’s a bit of a mixed bag over the next couple of weeks, with some proper grunt showing up later, but you’ll have to pick your moments.

The water’s sitting at 61°F, which is a touch warmer than usual for this time of year – not a bad little bonus.

First up, Thursday the 10th is pretty average. There’s surf around the 4ft mark in the morning, but it’s not doing much. The afternoon kicks up to 6ft from the WSW, but the energy is only moderate (744) and the forecast is questionable with those rain showers. It’s a bit of a write-off, to be honest.

Friday the 11th is similar – around 6ft of WNW swell. The morning has a gentle breeze and looks clean, but the scores are still low. Not much to get excited about, just a bit of a grovel.

Then things start to wake up. Saturday the 12th sees the swell jump to a solid 10ft from the WNW with a long 12-second period. The energy is strong (2677 in the morning), but it’s a lot of water for this reef. It’ll be big and powerful, but the cross-off wind will keep it reasonably clean. This is one for experienced surfers only.

Sunday the 13th is where it gets interesting. The swell drops back to a more manageable 5ft from the NW, and the morning glass is nearly dead with a slight air. The energy is still solid (681), and it says to expect very good surf conditions. This is a standout morning – a proper window of clean, lined-up reef waves. The afternoon backs off to 4ft, but you get a gentle offshore, so it stays clean.

Monday the 14th is poor – onshore winds and messy surf. Not worth your time. Tuesday the 15th is also a washout with fresh cross-onshore wind and lumpy conditions. Wednesday the 16th stays mediocre, with cross-shore chop.

Now, Thursday the 17th of September is a real one to circle. The swell is back up to 10ft from the WNW with a long 12-second period. The afternoon has a light cross-off breeze and it’s forecast to be clean. The energy is very strong (2133). This will be a proper session for the experienced crew – big, powerful, and lined up. It’s a standout.

Friday the 18th is another step down, with moderate winds and a dropping swell. Saturday the 19th gets messy again with a fresh cross-shore and building swell, reaching 12ft by the afternoon. Not great.

Sunday the 20th is big – 13ft in the morning with a long 13-second period and very strong energy (4853). The wind is cross-off, so it’ll be big and clean, but it’s a lot of water. This is expert territory.

Monday the 21st is looking like the best of the lot for a while. The swell is still a chunky 12ft from the west, but you’ve got a light offshore wind in the morning and a moderate offshore in the afternoon. The energy is very strong (3141 and 3217) and it’s forecast as excellent for experienced surfers. This is a serious day at Kilcummin Harbour.

Tuesday the 22nd is just too big. The forecast is for 15ft with a massive 15-second period – that’s an enormous, dangerous swell. The energy is off the charts (8912). It’s a pass, even for the best.

After that, it stays solid but messy. Wednesday the 23rd has a 10ft swell, but the winds are cross-shore. Thursday the 24th is a bit cleaner with a cross-off, but it’s still big. Then Friday the 25th looks like another promising one. The morning has a moderate offshore wind, 12ft of WNW swell, and the energy is strong (2412). It says excellent for experienced surfers – another good one to finish on.

So, if you’re looking for the best on offer, mark Sunday the 13th for a cleaner, slightly smaller reef session, and Monday the 21st for the big, powerful, and clean day. The second week has some size, but keep an eye on the wind.
