The Lowdown
Right folks, Rusty here. Let’s have a look at what’s on the cards for Bundoran over the next couple of weeks.
The forecast starts off pretty grim. We’ve got a few days of small, junky, and wind-affected surf to get through. Wednesday the 2nd and Thursday the 3rd are a write-off—small swell, messy winds, and just not worth paddling out for. Stuff really kicks off on Friday the 4th, but it’s not for the faint-hearted. A powerful 12ft swell from the west, with a long 12-second period, slams in, but it’s a total mess with 28 mph cross-onshore winds. The combined wave energy is massive (3529), but it’s blown out and dangerous. That’s a day for the experts only, and even then, it’s a battle.
Saturday the 5th offers a bit of a reprieve. The swell drops to a more manageable 5ft from the WNW, with a 10-second period, and the wind swings to a light cross-offshore from the SSW. That’ll clean things up nicely, and the combined energy sits at a moderate 555. It’s a solid morning session for intermediates.
Sunday the 6th is small again, and the wind stays tricky. The real standout, the one you’ve been waiting for, is Friday the 11th of September. The morning is looking absolutely glassy—zero wind, calm as a millpond—with a solid 12ft swell straight out of the west, 10-second period. The energy is pumping at 2058. That’s a true groundswell, maybe a bit too bowling for the beach with that period, but Bundoran is a reef, so it’s going to be lined up and powerful. This is a big-wave day for experienced surfers only. The water is much warmer than normal for this time of year, sitting at 63°, which is a nice bonus.
The following Monday the 14th of September also looks special. Another big 12ft west swell, this time with a 13-second period, and the afternoon goes glassy as well. The energy is a staggering 4519. That’s back-to-back days of heavy, clean, overhead reef waves. The best of the whole window is that Friday the 11th morning, though. If you’ve got the chops, get on it.
The second week has a few smaller windows, like Saturday the 12th with a 6ft offshore swell, but nothing beats those two glassy, powerful days in the middle of September. There’s a big gap of poor surf before that, so be patient.
Rusty.

Information about the Bundoran Surf forecast
The above surf forecast table for Bundoran provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Bundoran can be found by selecting the local surf guide option on the grey menu. Our Bundoran 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 (Bundoran) 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 Bundoran 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.
