The Lowdown
Alright, let’s switch over to the good ol’ imperial system.
Honestly, the first week and a bit is a slow one. We’re looking at a long stretch of small, choppy, or messy conditions. Not much to get excited about until we’re a week or so out.
The Peak is a reef break that needs a solid west swell. For the first few days, we’ve got tiny, weak, short-period WNW swell, but the wind is all wrong – cross-on or cross-off, and choppy. The wave energy is barely a blip.
Saturday the 15th and Sunday the 16th are small and weak. Monday the 17th is a little better, with a combined energy reading of 105, but the waves are ordinary. Tuesday the 18th sees the swell build to about 5ft, but the onshore wind has it chopped up. Wednesday the 19th is a big day – we get an 8ft west swell with an 11-second period, a proper groundswell. But the wind is howling at 18-19 mph, and it’s messy. That 1736 energy reading tells you it’s a lot of power, but it’s going to be a battle. Thursday the 20th stays big with an offshore wind, but the rain and lumpy conditions make it a tough go.
From the 21st to the 24th, it’s back to tiny surf. A real blank patch.
Now for the good stuff. Circle Tuesday, the 25th of August. That morning the wind is glassy, and we’ve got a clean 5ft west swell with an 11-second period. The combined energy is 596, and the conditions are set up for very good surf. The Peak should be reeling. Watch the crowds, though – this spot can get busy.
Wednesday the 26th still looks good in the morning with glassy conditions and a 4ft west swell, but the wind turns onshore later. Friday the 28th morning is another standout. Clear sky, glassy, with a 5ft WNW swell and a 9-second period. That’s clean, fun surf with moderate energy of 471. That’s a solid session.
The 30th sees another big pulse of 8ft swell, but the wind is onshore and lumpy. More of a challenge.
For my money, Tuesday the 25th and Friday the 28th are the ones to go for. Glassy, clean, and a solid west swell. That’s the pick.

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.
