The Lowdown
Alright, this is Rusty, and I’ve got a look at the surf for the next 16 days. Honestly, it’s a bit of a slow burn for The Peak, but there’s a golden nugget waiting for you if you’re patient.
The first few days are a write-off. Wednesday the 12th through to the end of the first week, we’ve got tiny swell and messy winds. The energy is weak (34 to 110), with cross-off and onshore winds ruining any chance of a clean wave. You’ll see small pulses of 1ft to 3ft, coming from W or WNW, but the period is short, under 10 seconds, and the wind is just wrong. It’s a stretch of poor conditions, with only a brief moment on Thursday morning the 13th offering “surfable but ordinary” waves at 2ft. The water is a touch warmer than usual at 61°, but that’s small comfort.
The second week doesn’t start much better. Monday the 18th sees a bit more size at 4ft, but the wind is onshore and choppy, with moderate energy (187). Tuesday the 19th pushes up to 5ft, but it’s onshore wind again, making it a messy, blown-out affair. The Peak is a reef break, so it needs a clean surface to work, and it’s not getting it.
Then, around Thursday the 21st, we finally get a little window. Light rain and a gentle offshore wind from the SE pop up, with clean conditions. The swell is small at 2ft, but it’s a clean, rideable wave. Not a standout, but a relief after the dry spell.
The real standout arrives on Wednesday the 26th of August. Afternoon sees a nice jump in size to 5ft from the W, with a light cross-off breeze and a clean surface. The combined energy jumps to 297 (moderate), and it’s genuinely good surf.
But the absolute best of the whole forecast is Thursday the 27th of August. The morning is glassy, with a 7ft swell from the W, a period of 11 seconds, and a massive energy reading of 1066. That’s a serious, powerful groundswell. The wind is glassy, and the conditions are rated excellent. This is too big for beginners, but for experienced surfers, it’s a proper session. The only caveat is the afternoon gets a bit onshore, so the morning window is the one to target. The swell direction is W, and the guidance says The Peak loves W swell, so that’s a perfect match.
After that, things taper off again into the end of the month, with smaller, wind-affected waves.
So, the long story short: there’s a long gap of poor surf, but the 26th afternoon and the 27th morning are the standouts. If you can wait, the 27th morning is the one to circle on your calendar.

Information about the The Peak Surf forecast
The above surf forecast table for The Peak provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at The Peak can be found by selecting the local surf guide option on the grey menu. Our The Peak 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 (The Peak) 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 The Peak 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.
The Peak 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.
