The Lowdown
Right, let’s talk about the surf. It’s been a proper messy start to the week, but hang tight because there’s some serious gold on the horizon.
The good news is, there’s a real window of clean surf shaping up for the middle of the period, and a couple of proper standouts that’ll have you checking your board’s wax. But we’ve got to get through a proper blitz of wind and swell first.
The first few days are basically a write-off. Tuesday and Wednesday are onshore and lumpy, and that swell energy is all over the place. It’s the kind of stuff that’ll have you fighting it the whole time. Then Thursday properly turns it on, with a big jump in energy, but it’s way too messy to be any fun. We’re looking at strong cross-onshore winds and a lumpy sea. Not worth it.
Now, here’s where it gets interesting. Friday morning, with the new swell, the wind finally swings and we get some clean conditions. That’s when it starts to feel right. Then Saturday and Sunday morning are looking sweet. The wind drops right off, we get that crisp, clean water. There’s a real window of quality here, with light winds and decent looking swell.
The standout, though, has to be the Tuesday morning session. There’s a long-period groundswell rolling in, and the ocean is glassy. That’s the one. It’s promising, but it’s also a week out, so let’s not get too ahead of ourselves. The swell direction is solid from the west-northwest, and we’ve got the juice behind it. That’s the kind of day you clear for.
Wednesday after that keeps the quality going with some clean, offshore winds. There’s a bit of a dip in size on Thursday, but then the following weekend pops off again. That Friday and Saturday period brings a big pulse of WNW swell, and the winds are looking offshore and clean. If that holds, the following Saturday morning looks like another serious contender.
There are a few days with no real recommendations in between, like the small windows on the 21st and 24th, but that’s just the ocean breathing. It’s not flat, just not clean.
So, if you’re picking your sessions, you wait for the clean windows. The big, clean Friday a week from now is one to watch, and that glassy Tuesday morning is the real gem. Just remember, a long period like that can break a bit straight at a beach break, so be smart about it out there. Get amongst it.
Later.

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.
