The Lowdown
G’day, I’m Rusty. Let’s have a yarn about what’s coming up at Bundoran.
Alright mate, the outlook for the next couple of weeks is a bit of a mixed bag. There’s plenty of swell on the horizon, but the wind’s often going to be a pest. The first few days are a write-off for a good paddle, but things start to look a bit more promising later on. The water’s sitting at a very warm 62°F, which is a solid 4°F warmer than usual for this time of year – that’s a big deal, and you’ll notice it on the first surf.
Right, the start of the period is a tough one. Friday the 4th of September has a solid 10ft of straight west swell, but with a 25 mph cross-onshore wind, it’s just messy, full-on, and not worth your time. Saturday the 5th is the one to look for. The morning is average with a 6ft westerly swell, but by Saturday afternoon the wind swings light southerly, going cross-offshore. That 4ft swell from the WNW with a consistent 10-second period will clean right up. The wave energy’s moderate at 328, but the clean conditions will make it the best on offer across the whole outlook. Expect a few locals out, as crowds are sometimes an issue, but for a reef break like Bundoran coming clean, you’ll be smiling.
Sunday the 6th and Monday the 7th drop off. Swell gets small and the wind stays too fresh and cross. By Tuesday the 8th, we’re looking at a big 12ft of west-northwest swell, but with a 25 mph cross-onshore again and rain, it’s all chop and no shape. That’s expert-only territory if you’re crazy enough to go out.
The middle of the week (Wednesday 9th through Friday 11th) stays disappointing. The swell is either too small or too wind-affected, and nothing clicks. There’s a couple of days there with nothing good to chase.
Saturday the 12th of September holds a 5ft swell from the WNW with a decent 10-second period, but the wind is onshore and the energy’s just moderate at 450. It’s not a standout.
Now, looking out to the second week, things get a little more interesting but still not perfect. Sunday the 13th of September morning is a sneaky little window. A light southeast offshore wind meets a 3ft swell from the WNW. Combined energy is low at 149, but with light winds and clean conditions, it’ll be rideable and not crowded. It’s small but clean.
Monday the 14th and Tuesday the 15th bring a much longer-period swell (14 seconds) from the WNW, up to 5ft. The energy jumps to strong levels (792) on Monday afternoon, which is promising for shape. But the problem is the wind: strong onshore again. It’s a classic groundswell that would be magic at a point or reef, but with that wind, it’ll be a mess. There’s a tiny window on Tuesday afternoon with a gentle cross-shore, but it’s marginal.
The last few days, from Wednesday the 16th to Saturday the 19th, see the swell fade away to small, weak signals under 3ft. The cleanest moment is Friday the 18th of September morning, with a light SSE offshore and a 3ft WNW swell. It’s small, but glassy. Don’t get your hopes up for much more than a longboard glide.
So, the best call is still Saturday afternoon, the 5th of September at Bundoran – that 4ft clean swell is the only real gem in the rough. For the second week, keep an eye on Sunday the 13th for a clean, small session.
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.
Bundoran is 20 km (12 miles) from Killybegs. If you plan a holiday in Donegal, look for hotels and other accommodation in Killybegs. Killybegs has rooms for a wide range of budgets as well as car hire and transport links.
