The Lowdown

G’day, Rusty here. Look, the next 16 days at The Peak are a bit of a mixed bag, but there’s some real potential lined up if you’re patient. The overall pattern is a slow start with a lot of wind and lumpy, poor surf, but it builds into a very promising second week with some clean, solid groundswell.

The first real chance to get wet doesn’t come until the afternoon of Thursday the 5th of September. The Peak is seeing a 4ft swell from the WNW, with a 10-second period. The wind is a light cross-off from the SSW, keeping things clean. The water is sitting at 63°, which is 5° warmer than usual for this time of year – that’s much warmer than normal, a real treat. The wave energy is moderate (328). It’s a good, honest start to the run.

From there, things get ugly. Sunday the 6th and Monday the 7th are a write-off with strong winds and garbage conditions. Then Tuesday the 8th of September is dangerous – big, messy 12ft to 10ft WNW swell with strong onshore winds. That’s a hard pass for anyone, even the experts. That combined energy is a massive 2409, proper strong stuff. The surf stays poor and mostly onshore right through until the 11th, just a lumpy, choppy mess. The 12th and 13th have some cleaner moments but the swell is small and weak.

The standout window begins on Monday the 14th of September. The wind is light from the SW, cross-shore, and the swell bumps up to 7ft from the W at 12 seconds. That’s a long-period groundswell with real grunt (1388 combined energy). It’s a little on the bigger side, best for experienced surfers, especially at a reef break. The morning is the pick, but the cross-on wind in the afternoon messes it up a bit.

The true highlight, though, is Thursday the 17th of September. The morning glass is off, with a 8ft swell from the W at 10 seconds. The wind is pure offshore from the SE. Conditions are clean, and the wave energy is strong (1231). This is great for experienced surfers, but the size is pushing it for beginners. The crowds are listed as “sometimes,” so you might have company, but it’s worth it.

The run continues strong into Friday the 18th of September. Absolutely glassy conditions in the morning with a 7ft W swell at 10 seconds. The energy is pumping (1004). This is excellent surf for those who know what they’re doing. The afternoon stays clean with a light cross-off breeze. Saturday the 19th keeps the offshore flow going, with a solid 6ft swell from the W. The week closes out on Sunday the 20th with a clean 4ft WNW swell and a gentle offshore breeze. Consistent, clean, and good.

So, for the best of the 16 days, lock in the morning of Thursday the 17th of September for the best combination of size, clean offshore wind, and strong energy. The morning of Friday the 18th of September is a very close second, especially if you prefer glassy conditions. The early part of the period is a complete write-off, but the second week redeems it all.

Stay tuned, forecasts can change, but this one looks promising. 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.
