The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s cooking at The Peak over the next couple of weeks.
Right off the bat, I gotta be straight with you – the first chunk of the forecast is a real dud. We’re looking at a flat spell from Wednesday the 26th right through the weekend. The waves are barely a ripple, with the odd 1 ft to 2 ft west swell showing up, but it’s just not doing anything for us. The wind is messy, the energy is weak (as low as 12), and the score is a big fat zero. You’re better off waxing your board and waiting.
Things start to get a pulse on Monday the 31st. The swell jumps to 4 ft from the west with a moderate energy reading of 245, but the wind is a cross-onshore mess at 25 km/h, and it’s raining. Not the best, but it’s a sign of life. Tuesday the 1st of September is similar, with 4 ft west-northwest swell and a cross-off wind, but it’s still just marginal. The water temp is about average for the time of year, nothing to write home about.
Now, the standout window. If you’ve been patient, the reward comes on Thursday the 3rd of September. The swell hits 6 ft from the west-southwest with a solid 11-second period – that’s real groundswell energy moving through. The combined energy is a strong 775. The wind is a moderate cross-shore though, which will put some chop on the face. It’s a bit of a mixed bag, but it’s the best on offer by a long shot. The waves will be pushing into the expert range, so if you’re not confident, maybe sit this one out. The Peak is a reef break, so that long-period groundswell will wrap in nicely, but the cross-shore wind will mean you’ve got to work for the clean ones.
We’ve got another promising pulse rolling in on Monday the 7th of September. The swell is a solid 10 ft from the west-northwest, with a combined energy of 1346 – that’s a serious wall of water. This is strictly for the experienced crew. The morning has a clean, cross-off wind from the south-southwest, but the peak of the swell is huge. By the afternoon, the wind swings onshore and it’s all over. This is a big, powerful, long-period groundswell (9-second period), and at a reef like The Peak, it will be a freight train. It’s a long-range call, so keep an eye on it, but it looks like the real deal.
The rest of the run is a mix of clean but small surf, or bumpy and blown-out conditions. The last decent chance is Wednesday the 9th of September, with a clean 3 ft west swell and a light cross-off breeze. Energy is a moderate 120, so it’s surfable but nothing to get too excited about.
So, to wrap it up: the first week is a write-off. Your best bet is the morning of Thursday the 3rd of September for the first big groundswell, and then circle the morning of Monday the 7th of September for the really big, expert-only stuff. Get out there and earn it.
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.
