The Lowdown
Alright lads, Rusty here. Let’s break down what’s shaping up at Bundoran.
The water’s 62°F, which is a fair bit warmer than usual for this time of year.
First chance to get wet is Saturday afternoon, 5th September. It’s a small 4ft swell from the WNW with a 10-second period. The combined energy of all swells directed here is 328 (moderate wave energy). The wind’s a light cross-off, so it’ll be clean, but it’s tiny and nothing special. Not a standout.
From Sunday the 6th right through to the 12th, it’s mostly poor – strong winds, mess, and small, weak waves. A few days are completely flat. The 8th has a big 12ft swell from the WNW but it’s getting hammered by a strong breeze, so it’s a total mess. That’s kite-surfing territory.
Now, the real standout. Thursday the 17th of September. In the morning, you’ve got a solid 8ft swell from the west with a 10-second period. The combined energy of all swells directed here is 1231 (strong wave energy). The wind is a light offshore from the SE, making it glassy and clean. By the afternoon, it’s 8ft from the west, an 11-second period, and glassy. The combined energy of all swells directed here is 1538 (strong to very strong wave energy). That’s the best of the whole forecast. The swell is over 8ft, so it’s for experienced surfers only. The long period (11 seconds) means the waves will have real punch and shape, with longer lulls between sets – ideal for a reef break like Bundoran.
Friday the 18th and Saturday the 19th are still decent, with 7ft and 6ft west swells, clean and offshore or glassy, with combined energy readings of 1004 and 656 (strong and moderate wave energy). That’s good, solid surf.
By Sunday the 20th, it’s fading back to 4ft and 3ft, still clean but nothing to get excited about.
The 17th is the clear winner – big, clean, powerful swell. The first week is a dud, but that mid-September window is the one to target. Keep an eye on it, it’s promising.
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.
