The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s in store for Bundoran over the next couple of weeks.
Right off the bat, I gotta be straight with you – it’s a slow start. The forecast is looking pretty ordinary for the first week and a half. We’ve got a long gap here with nothing worth getting excited about until the very end of the run. For the first two weeks, the swell is small and the wind is mostly cross or onshore, meaning the waves will be messy and small. It’s a tough stretch.
Let’s get to the one real standout. Mark your calendars for Tuesday the 25th of August. That’s the day it all comes together. We’re looking at a solid 7ft to 7ft groundswell rolling in from the WNW with a long 9 to 10 second period. The combined energy hits a strong 850 (for the afternoon), so there’s plenty of grunt behind it. What makes this special is the wind: a light 6 mph offshore breeze from the SSE. That’ll keep the faces clean and lined up. This is proper, powerful surf, and it’s going to be a good one. Given the size (over 5ft but under 8ft), this is for intermediate and above – beginners might find it a handful. And with Bundoran being a reef setup, that long-period swell will wrap in beautifully. The crowds are *sometimes* a factor here, so expect company if the word gets out.
Before that, the only other mentionable window is around Tuesday the 18th of August with a small 3ft bump, but the wind is wonky and the conditions are just *surfable* – nothing special. Then from the 19th onward, the swell builds but the wind turns onshore and stays that way until that clean spell on the 25th. There’s a moment on Saturday the 22nd in the morning with glassy conditions and a tiny 4ft swell, but it’s weak and short-period.
As for the water, Bundoran is running a touch warmer than normal for this time of year, about 61°F, which is a degree and a half above average – feels nice on the skin.
So, to sum it up: the first two weeks are a write-off for decent surf. But that Tuesday the 25th is the real deal – a proper, clean, powerful swell with clean offshore wind. That’s your window. Keep an eye on it, but it’s looking 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.
