The Lowdown
Alright, folks, Rusty here. Let's have a look at what's on the table for our local stretch. We're staring down a pretty lean 16-day window, I'm not gonna lie. The first few days are a write-off, but there's a glimmer of hope if you're willing to wait.
The whole period kicks off with a real dud. Thursday the 20th is a total mess with a strong cross-onshore wind and lumpy, poor surf. That sets the tone for the next few days – we're looking at tiny, weak waves and onshore breezes through the weekend and into Monday the 23rd. Honestly, it's a proper flat spell, so don't bother paddling out.
Now, if you're patient, things start to shift around Monday the 24th. The combined energy jumps to 313 (moderate wave energy), and we get a clean little swell. The morning is a highlight, with a WNW swell of 4ft and a 11-second period pushing in. The wind is a light cross-offshore, keeping the surface clean. The afternoon holds up with a similar WNW swell at 4ft and a clean 10-second period, with a gentle offshore breeze. This is the real standout of the whole forecast. The water temp is sitting at 62°, which is a touch warmer than normal for this time of year, so you might not need the thickest wetsuit.
After that little burst, Tuesday the 25th and Wednesday the 26th see the swell drop right back off. The energy is weak, down to 86 or less, and though the wind is offshore and clean, the waves are just too small to get excited about. Thursday the 27th morning offers a tiny, glassy 2ft swell, but it's just not enough to call it a session.
The following week, from the 28th August through to the 4th of September, is a real mixed bag of small, short-period, weak swells. There's a marginal morning on Friday the 28th with a 4ft WNW swell (212 energy), clean but with a short 8-second period, so it'll be a little walled-off. The only other pulse of note is on Thursday the 3rd of September, when a 4ft NW swell rolls in with glassy conditions in the morning. The energy is a moderate 140, but it's only a 7-second period, so it's not going to be holding up great.
Overall, it's a quiet stretch. Save your energy for that Monday the 24th session – it's the best of a pretty average bunch.
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.
