The Lowdown
Righto, mate. Rusty here.
Straight off the bat, The Peak is the only game in town across this whole 16-day stretch, but it’s not gonna be a constant party. There’s a proper rough patch to get through first. A big, strong westerly swell fills in late on Friday the 4th with some nasty onshore wind, making it a write-off. That mess hangs around through the weekend and into the start of next week, so you’re looking at a solid gap of no-go conditions until things finally start to clean up.
The real standout window kicks off on Monday the 14th of September. That morning, the sky clears and a light SSE breeze swings offshore, cleaning up a solid 5ft W groundswell running at 11 seconds. The energy is moderate with combined energy of 640, but with those conditions, expect clean, lined-up waves. It’s a reef break that’s fairly consistent, and with a west swell at an exposed spot, it’ll be working well. You might have company though – crowds are sometimes an issue here. Tuesday the 15th looks like the absolute pick. Another clear morning, same light offshore SSE wind, and the swell holds at 6ft from the WNW with an 11-second period. The energy is still moderate (815), but the combination of size, period, and glassy-offshore conditions makes for the best surf of the whole outlook. Water temp is about average for this time of year, so no dramas there. As we head into the second week, Wednesday the 17th and Thursday the 18th both offer clean 5ft WNW swell with light offshore winds, keeping the fun rolling with consistent chest to head-high sets.
For the beginner crew, watch out – that 6ft on the Tuesday is getting up there; it’s not huge but it’ll have some push. If you’re an expert, you’ll be all over the cleaner mornings.
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.
