The Lowdown

Alright, folks, Rusty here. Let’s have a look at what the next couple of weeks have in store for us at Kilcummin Harbour. It’s a bit of a mixed bag, so let’s break it down.

The opening days are a bit of a tease. We’ve got some solid swell showing up, but the wind is going to be a problem. Friday afternoon kicks things off with a cross-off breeze and a 8ft WNW swell, but the energy is a bit jumbled (1255) and the whole thing is pretty marginal. Not the cleanest start.

Saturday morning looks a little better, with a cleaner 7ft W swell and a moderate offshore wind. It’s surfable, but it's not setting the world on fire. That window closes quickly, with the afternoon turning cross-off and the conditions getting messy. Sunday is a total washout with light cross-onshore winds and a dropping, weak swell. Don’t bother.

Things go flat and quiet for a few days after that. We’re looking at some small, weak pulses through the middle of the week, nothing that’s going to get your heart racing. The wind is mostly offshore or cross-off, but the swell is just too small, with heights barely reaching 3ft. It’s the kind of lull that makes you want to check the tide charts and think about other things.

But hang on, because there’s a real standout building for the following weekend. Saturday the 16th looks proper. We’ve got a 5ft to 6ft W swell rolling in with a 10-second period and a gentle cross-off breeze. The energy is building, sitting around 522-614, and the conditions are looking clean. This is the one to circle on the calendar. It’s the best combination of size, wind, and cleanliness we’ve seen in the whole run.

That window is short-lived though. Sunday the 17th sees the wind swing onshore and the surf gets messy, and it stays that way through the middle of the following week. There’s another small glimmer of hope on Thursday the 20th, with a light offshore and a 5ft W swell, but it’s not as clean or as powerful as that Saturday.

The final stretch into the 22nd is just small and unremarkable. The water is running a touch warmer than average for this time of year, which is a nice little bonus, but it doesn’t change the fact that the surf is mostly a write-off.

So, there you have it. A long, flat spell, but one genuinely good day on Saturday the 16th. It’s a long way out, but that one has some promise. The rest is just waiting for the next pulse.

Rusty.

Information about the Kilcummin Harbour Surf forecast

The above surf forecast table for Kilcummin Harbour provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kilcummin Harbour can be found by selecting the local surf guide option on the grey menu. Our Kilcummin Harbour surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kilcummin Harbour) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Kilcummin Harbour may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
