The Lowdown
Alright folks, Rusty here. Let’s talk about Bundoran, a solid reef break that’s normally pretty dependable. But for the next 16 days – from now right through to the start of August – the forecast is a real letdown. Honestly, there’s not a single session worth paddling out for. The whole window is stuffed with onshore and cross‑onshore winds, tiny swell, and poor surf conditions. Even the water is acting weird – it’s sitting at 64°, which is a whopping 6° warmer than usual for this time of year. That’s very unusual.
The first few days – Friday 17th through to Thursday 24th – are dominated by weak, short‑period waves (mostly under 2 feet, periods 5–8 seconds) and moderate onshore breezes. The combined swell energy barely reaches 46 (weak) at best. It’s messy, bumpy, and not worth a second look.
Then around Saturday 25th and Sunday 26th, a bit more swell shows up – 5 to 6 feet from the WNW, with periods around 10 seconds. The energy jumps to 522 (strong) on Saturday morning, but the wind is cross‑shore or cross‑onshore, and the surf report says “marginal” at best. It’s not clean. The waves are there but the quality is poor, and with the reef setup, a cross‑shore wind can make things tricky. Still, for a short window the swell is there, but it’s not a standalone highlight.
The rest of the period – from Monday 27th through to Saturday 1st August – stays onshore or cross‑onshore, with swell dropping back under 5 feet and energy fading. On Monday 27th the swell hits 7 feet (strong energy at 867), but it’s accompanied by 12–15 mph onshore winds, so it’s choppy and blown out. That’s only for the experts, and even then the conditions are poor.
For a break that’s “fairly consistent” under normal circumstances, this 16‑day blank run is unusual. The forecasts could change, but right now there’s nothing to get excited about. Keep your board waxed and check back later.
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.
