The Lowdown
G’day, Rusty here. Look, it’s a bit of a mixed bag for the next couple of weeks at The Peak. The southwest flow keeps things onshore and lumpy for long stretches, but there are a couple of clear windows where it all comes together. The water temperature is about average for this time of year, nothing unusual there.
Wednesday morning, September 2nd, we’ve got a clean start with a gentle offshore breeze out of the southeast at 9 mph. Swell is small at 2 ft from the west with a short 8-second period. Combined energy is weak at (57). It’s surfable, but very ordinary. Not a standout.
Friday the 4th sees a big jump in size – 12 ft from the west, with a 12-second period, energy readings are up around (3704). But that’s a strong cross-onshore wind from the west at 28 mph with rain showers. The Peak will be messy and blown out. That’s more of a kite-surfing day than a paddle session.
Saturday the 5th improves a little. The morning is still marginal with a 6 ft west-northwest swell and a moderate cross-shore. The afternoon is the pick of the near-term: a light southerly breeze at 6 mph, clean conditions, and a 5 ft west-northwest swell with a 10-second period (341 energy). That’s the best on offer in the first week. Crowds are possible here sometimes, but with those conditions, it’ll be worth the paddle.
After that, the swell drops right off. From Sunday the 6th through to Friday the 11th, it’s mostly poor with onshore winds, chop, and messy conditions. There’s a run of no recommended surf for over a week.
Then we get a bit of hope. Sunday morning, September 13th, a gentle southeast offshore breeze, 3 ft west swell, 10-second period, and clean conditions (226 energy). It’s not big, but it’s clean and rideable. That’s the other standout, though you’ll need to wait for it.
Monday the 14th drops back to tiny 2 ft, and after that it’s almost flat by the 15th. Wednesday the 16th has a 3 ft west swell with a long 12-second period, but light cross-shore winds make it marginal and tide-dependent.
Overall, the one true standout is Saturday afternoon, September 5th at The Peak. Clean, manageable size, and a bit of energy. The other good window is Sunday morning, September 13th, but it’s further out, so keep an eye on 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.
