Kilcummin Harbour Surf Forecast and Surf Report

Alright, Rusty here, let’s get into this in feet and Fahrenheit.

Looking at the whole 16-day window, we’ve got a slow start but things build into some serious size and power, especially towards the back half. The first few days are worth a paddle but nothing to lose sleep over, then we get a proper pulse of groundswell that will have the experienced crew licking their lips, though the wind gets messy in the middle. This is a reef set-up, so when that long-period energy arrives, it’ll line up nicely here.

Water temp is sitting at 60.3°, which is a touch warmer than normal for this time of year – about 2.7° above average, so it’s a little more pleasant than you’d expect.

We have to hang tight through the start of the period. There’s nothing really worth getting excited about until Sunday morning the 13th at Kilcummin Harbour. That morning brings a clean 5.2ft NW swell with an 11-second period, light offshore wind from the south at 6 mph, and the wave energy is at a moderate 715. It’s clean, lined up, and very surfable. The afternoon stays clean but drops a little in size to 4.6ft with the same NW direction.

Monday the 14th is ordinary. The morning is small and average at 2.6ft with 195 energy, and the afternoon has a bigger 4.9ft swell but the wind picks up to 19 mph from the SSW, making it a fresh offshore. It’s surfable but messy.

Tuesday the 15th is a write-off. Clean looks gone, wind swings cross and cross-on, and the swell bumps up to 6.9ft to 7.2ft but it’s lumpy and poor. Not worth a session.

Wednesday the 16th picks up a bit. Morning has 7.9ft of WNW swell but it’s cross-shore with a moderate breeze – you can surf it if you’re desperate, but it’s not clean. The afternoon cleans up with a cross-off wind and 6.2ft from the west at 10 seconds, energy at 852. It’s okay, nothing special.

Now Thursday the 17th is where things get heavy. Morning is 9.8ft from the WNW, but it’s cross-shore with 19 mph winds and lumpy as hell. The afternoon jumps to 16.4ft of WNW swell at 13 seconds – that’s a very long period groundswell – with energy screaming at 8248. But the wind is cross-shore and strong at 22 mph, so it’s a messy, dangerous beast. Only for the hardcore, and even then, it’s sketchy.

Friday the 18th is a big turnaround. Morning is 13.1ft from the WNW, 13-second period, with a cross-off breeze from the SW at 19 mph – and it’s clean. Energy is 6040. The afternoon is even better: 11.5ft, still 12-second period from WNW, but now the wind is a moderate offshore from the SSW at 16 mph, and it’s clean. This is excellent surf, but at this size and power, it’s for experienced surfers only. This is a standout morning and afternoon for bigger-wave crew.

Saturday the 19th is let down by the wind. Morning has 9.8ft from WNW, clean enough but wind is a strong 25 mph cross-off, really pushing. That’s messy. Afternoon spins to strong cross-shore and the waves are lumpy at 11.5ft – skip it.

Now, if I had to pick the real standout of the whole period, it’s Sunday the 20th morning. We’ve got 13.1ft of WNW groundswell at 13 seconds, light SW wind at 9 mph, clean conditions, and energy at 5133. That’s exceptional for experienced surfers. The afternoon stays solid with 11.5ft and offshore wind from the south, but the morning is the pick.

Monday the 21st is still big at 9.8ft to 11.5ft from WNW, but the wind is a fresh cross-off, so the surface isn’t perfect. It’s surfable but not as clean as the Sunday session.

Tuesday the 22nd is another write-off. Swell drops to 8.2ft to 11.5ft but wind is cross-onshore and choppy. No good.

Wednesday the 23rd morning
