The Lowdown
Alright, let’s break it down. The Peak (reef) is the only break we’re looking at, and there’s a slow start with no proper swell at the beginning. The first real chance to get wet is Saturday afternoon on the 5th of September.
That Saturday afternoon session is the opener: a 1.6m swell from the W, with a 9-second period. The wind is a gentle cross-offshore from the SSW, giving us clean waves. The combined wave energy is 402 (moderate). It’s a solid little session to warm up.
The rest of the first week is mostly a write-off. Thursday the 3rd and Friday the 4th of September see a big jump – 2.5m to 3.5m of W swell – but the wind is a strong cross-onshore, making it a choppy mess. Energy hits 3728 on Friday morning (very strong), but the conditions are too raw for paddle surfing. That’s kite surfing territory.
We’ve got a couple of real gems later on. Saturday the 12th of September is the standout: a 3.0m swell from the WNW with a very long 13-second period, and a gentle offshore breeze from the ESE. That’s groundswell magic for a reef break. The energy is 2602 (very strong), and it’s considered excellent for experienced surfers. The water temp is about normal for the season.
Sunday the 13th of September is also clean, with 2.0m to 2.1m WNW swell going glassy by the afternoon. The energy at 717 (moderate) is still very good.
Between the 5th and the 12th, there’s a few days of poor wind or weak swell. The long-range call on the 12th and 13th is the one to pin your hopes on, but it’s a bit far out to lock in. The Peak can get crowded sometimes, so plan accordingly.
If you’re after the best, Saturday the 12th of September is where it’s at – big, long-period groundswell, offshore wind, and a reef to make it all line up.

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.
