Kilcummin Harbour Surf Forecast and Surf Report

G’day, it’s Rusty here, and I’ve been staring at the charts for Kilcummin Harbour, and honestly, it’s a bit of a mixed bag. We’ve got a slow start, a rough patch in the middle, but a decent little window at the end of the first week that looks like the pick of the lot. The water temp is sitting at 61°F, which is a touch warmer than usual for this time of year, so you won’t need the thickest rubber, just a good wetsuit.

The week starts off pretty ordinary, with the Tuesday morning session at Kilcummin Harbour (Kilcummin-Harbour) being a write-off. There’s a small 3ft northwest swell rolling in with a 9-second period, but the cross-off wind from the SSE is making it messy, and the energy is only weak to moderate at 137. The afternoon cleans up a little with a proper offshore, but it’s still pretty average, and the swell drops slightly to 2ft.

Wednesday’s a bit better, with a WSW swell at 3ft and a bit more period behind it on the morning session. The wind is holding offshore, so it’s clean, but the energy is still only moderate at 146. The afternoon is similar, just a touch less energy. These are surfable waves, but nothing to get too excited about.

Then things start to pick up a little on Thursday. The swell bumps up to 4ft from the west, with a 10-second period, and the energy jumps to a solid moderate reading of 246. The wind is offshore in the morning, and the call is for good surf conditions. This is when it starts to feel like a surf trip, not just a paddle around. The afternoon stays clean too, with a gentle cross-off. This looks like the first session worth pointing the car at.

Friday and Saturday are a letdown, to be honest. The swell pushes up a bit—4ft on Friday morning, building to 5ft by Saturday—but the wind swings onshore and cross-shore, and the wave state gets chopped up. The energy is picking up, but it’s messy, and the period drops off to 7 or 8 seconds. That’s not the kind of surf you want. The quality just isn’t there.

Sunday morning has some light rain and a 3ft WNW swell, but the period is only 7 seconds, and while the wind is offshore, the wave quality is still poor. The afternoon is weaker again, a 2ft N swell with a slightly better 9-second period. It’s ordinary.

The following week starts off with small, clean, but pretty weak surf on Monday, with 3ft and a 9-second period, but the energy is dropping into the double digits. Tuesday brings a bit more swell, but the period is short again, and the wind is messing with it.

Now, here’s where it gets interesting. If you can wait until Thursday the 20th, there’s a proper pulse of swell. The height jumps to 7ft from the WNW with a 10-second period, and the energy is strong at 929. The wind is cross-offshore, so it’s clean, but at 7ft, this is pushing past beginner territory. You’ll want your wits about you.

But the real standout is Friday the 21st. That morning, we’ve got 8ft of WNW groundswell with an 11-second period, and the energy is very strong at 1598. The wind is a fresh offshore from the south, which will groom it nicely. This is the biggest, cleanest swell of the window, and at this size, it’s strictly for experienced surfers. The afternoon holds similar size, and the energy is still huge. This is the one to circle on the calendar, but with a warning—8ft at a reef break like Kilcummin is heavy, it’s not for the faint-hearted.

After that, Saturday the 22nd turns nasty again with strong cross-onshore winds and lumpy, messy surf. The swell is still there, around 5ft, but it’s blown out. The rest of the weekend and into Monday is more of the same—windy and messy, with energy levels all over the place. There’s another pulse on Tuesday the 25th with 8ft from the NNW and a 9-second period, but the wind is cross-shore and lumpy, so it’s not going to be clean.

So here’s the straight talk. The best on offer is Friday the 21st at Kilcummin Harbour, hands down. Big, clean, and powerful. If you’re not up for that, Thursday afternoon the 20th is your next best bet. The rest of the window is pretty average, with a lot of blown-out and messy days. Stay patient this week, and be ready for the 21st.

Rusty, out.
