The Lowdown
Alright, let’s break this down. Bundoran is a proper reef setup, and it’s going to take its time this run. The first week is mostly a write-off with a lot of wind and chop, but there are a couple of windows later that you need to have your eye on.
The absolute standout session is on Monday the 14th of September. That morning you’ll have clean, glassy lines with an offshore ESE wind swinging to a cross-offshore SSW. The swell is a clean 3ft from the west, but the period is a very long 12 to 13 seconds. That’s real groundswell, and on a reef like Bundoran, it’s going to create some lined-up, punchy waves. The combined energy is moderate (239 – 259). The water temp is about normal for the time of year. It can get crowded here sometimes, but a weekday in September should thin the pack out.
Before that, Tuesday the 8th of September morning is worth a look. A solid 7ft W swell with a 10-second period and a clean cross-offshore S wind. The energy is strong (849). That’s a big, powerful wave for intermediate guys and up. The afternoon gets bigger and more unruly, so the early session is the one.
On Saturday the 5th of September, the afternoon could yield a small but rideable wave with a 3ft WNW groundswell and light winds. It’s marginal, but it’s something.
The first week is mostly grim. Friday the 4th of September brings a massive, dangerous 10ft swell from the west with howling 45 km/h onshore winds. That’s a stay-on-the-beach day. The gaps between anything decent are three or four days, so don’t bother checking in every day.
The second week is smaller but much cleaner. Monday the 14th is the clear winner. The 16th has clean offshore winds but just tiny, weak waves.
Lock in Monday the 14th of September. That’s your day.
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.
