The Lowdown
Alright, let’s break down what’s coming for The Peak. We’re looking at a reef setup here, west-facing, and there’s some juice on the horizon, but we gotta sit tight through a lot of flat days.
First up, there’s a big stretch of nothing from Friday the 21st of August all the way through to the morning of Sunday the 23rd. Tiny waves, messy wind, just not worth the gas. You’re better off doing anything else.
Sunday the 23rd has a glassy morning, but the swell is only 0.7ft, so it’s basically flat. Nice to look at, that’s it.
Now, Monday the 24th of August is when the surf finally wakes up. Swell runs 4ft out of the WNW with an 11-second period, and combined energy hits 265 – moderate but solid. Winds are light and clean, cross-off in the morning. It’s not huge, but it’s the first real surf of the period. Water temp is 63°, which is about 4° warmer than normal for the season – noticeable and nice.
Then we get the real standout. Thursday the 27th of August morning, the swell jumps to 7ft at 8 seconds from the WNW, energy surging to 574 – strong stuff. Winds are light cross-off, clean conditions, and the forecast says “very good surf conditions.” The period is short so it’s wind swell, not groundswell, but at that size it’ll punch hard. The afternoon holds 6ft and clean too. Over 5ft, it’s expert territory, so keep that in mind. Crowds? The peak can get busy sometimes, but with this quality, you’ll have company.
After that, the 28th through the 30th drops back into mostly poor, choppy, onshore slop. If you’re into kite surfing, a few of those windy days might be more fun than paddling.
Then, the morning of Monday the 31st of August is another standout. Swell back up to 6ft from the west, 9-second period, combined energy of 561, with light offshore breezes from the ESE. That’s glassy, clean, and the reef will be working. The afternoon gets a bit of onshore wind, so hit the morning session hard.
From September 1st through the 5th, it’s a long run of poor conditions – strong onshore winds, tiny surf, energy in the single digits. There’s a weird reading on the 3rd of September afternoon with a 12-second period but only 0.7ft of swell – interesting on paper, not ridable.
Bottom line: Thursday the 27th of August morning and Monday the 31st of August morning are your best shots. The rest of the 16 days is mostly waiting.

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.
