The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the table for The Peak over the next couple of weeks.
First off, I’m not gonna lie to you – the next several days are a write-off. The Peak is a reef break that needs a clean W swell and offshore winds, and we’re getting neither. It’s a rough start. From Tuesday the 4th right through to the end of the first week, it’s a mess of cross-on winds, short-period windswell, and poor surf. The combined energy is weak, sitting at just 8 (on Tuesday morning) to 770 (on Friday afternoon), but none of that matters when the wind is ripping onshore. The water temp is about average for the time of year, nothing special.
We’ve got a solid gap of poor conditions until Sunday the 9th, but even then, it’s still not happening. The wind finally goes light and offshore on Monday morning the 10th, and the swell drops to 4 ft from the WNW with a period of 8 seconds. That’s a small, clean window with combined energy of 202 – moderate energy. The wind is glassy out of the north, and that’s a major positive. The Peak will be rideable, but the swell is small and short-period, so expect it to be a bit fat and weak. Crowds are possible here, so get in early.
After that, we’re back into a lull. From Tuesday the 11th through to Saturday the 15th, it’s tiny to flat, with only a few scraps of 0.7 ft to 2 ft of swell. The wind is light, sometimes offshore, but there’s just no juice. A gap of nearly a week with nothing worth paddling out for.
Now, here’s the standout. Look ahead to Monday the 17th of August. The morning brings a 6 ft swell from the WNW with a period of 11 seconds – that’s a proper groundswell with long gaps between sets, perfect for a reef like The Peak. The combined energy is 783, strong wave energy. The wind is offshore from the SSE at 10 km/h, so it’ll be glassy and clean. This is the best on offer in the whole outlook. The swell direction (WNW) is a solid match for the optimum W direction. The swell is over 5 ft but under 8 ft, so it’s fine for most surfers, but bigger for beginners. The long period means the waves will have shape and power, and paddling out will be easier between sets. The afternoon drops off to 5 ft with cross-off wind, still clean but weaker.
The Tuesday the 18th is a write-off again – strong cross-on winds and messy surf. The Wednesday the 19th is no better.
So, if you’re patient, that Monday the 17th is your window. The rest of the run is a dud. Don’t hold your breath for the second week; it’s mostly poor.
Rusty.

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.
