The Lowdown
G’day, Rusty here. Look, I’m gonna keep it real: the next couple of weeks at The Peak are mostly a bust. There’s a long stretch of poor conditions before we finally get a proper session. The first solid call doesn’t come until Tuesday, 25th August, so you’re gonna need some patience.
The water’s at 61°, which is a touch warmer than average for this time of year. Not a big deal, but it’s a little more comfortable.
From Tuesday afternoon, 11th August, through to Sunday, 24th August, it’s mostly tiny, weak surf with crappy winds. The swell energy is often in the low double or triple digits, with many days under 100 (weak) and only a few touching the low 100s (moderate). Winds are a mess – cross-off, onshore, or cross-onshore – and the wave height rarely tops 2 ft. The Peak is a reef that needs a clean W swell, and it’s just not happening. There’s a glassy moment on Monday morning, 17th August, but the swell is only 1 ft and the energy is 27 (weak), so it’s barely a ripple.
The first glimmer is Tuesday, 18th August, with a 3 ft W swell (period 8s) and clean cross-off wind in the morning, but the energy is just 110 (moderate) and it’s only “surfable but ordinary.” A tease. Wednesday, 19th August, bumps up to 4 ft with energy of 548 (strong), but the wind is onshore and it’s called “marginal” – not worth it.
The standout is Tuesday, 25th August. This is the day. The morning brings a 7 ft W swell, period 9s, with a sweet offshore SE wind at 6 mph. The combined energy is 675 (strong), and the call is “expect very good surf conditions.” The afternoon gets even better: 7 ft from the WNW, period 10s, still with light offshore SSE wind, and energy of 850 (strong). This is real groundswell with some punch. The Peak (United States) loves a W swell, and with offshore winds, it’ll be clean and well-shaped. This is the best of the whole 16 days.
But a heads up: 7 to 7 ft is big. It’s too much for beginners, and at over 7 ft, it’s expert-only, especially on a reef. The period isn’t super long (9-10s), so set intervals won’t be huge, but there’s plenty of energy. Crowds are listed as “sometimes,” so you’ll see a few others, but with conditions this good, it’s worth the company.
Wednesday, 26th August, still has size – 7 ft in the morning, and 8 ft in the afternoon – but the wind swings onshore from the NW, and the energy is a massive 1021 (strong to very strong), but it’s “marginal.” That 8 ft afternoon swell is huge; only for the brave, and the onshore wind will chop it up. Not the day.
So, bottom line: you’ve got a lot of flat, windy, or tiny days to get through, then smash it on Tuesday, 25th August. That’s your one true window. The rest is a write-off.
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.
