The Lowdown
Right then, I’ve had a good look at what’s coming up for The Peak. It’s a reef break, exposed to the west, and it likes swell from the west – so it's set up for the right swell.
Honestly, the first week and a bit is a write-off. There's nothing worth paddling out for until the morning of Saturday the 19th. That's a long gap of almost nothing but messy, blown-out junk. You’ve got some size early on, but it comes with strong cross-onshore winds that turn it into a lumpy, choppy mess. Not worth the effort.
The real standout is the morning of Wednesday the 23rd. That’s the one to circle. Swell is a clean 7 ft from the west-northwest, with a solid 14-second period – proper groundswell. The wind is a light cross-offshore breeze from the east at just 3 mph, which will have The Peak looking absolutely pristine. This is for experienced surfers only at that size on a reef. The combined energy is strong (1379), and the afternoon stays excellent with a 7 ft west swell and a clean offshore. That’s the best window of the whole run.
The Saturday the 19th morning is your next best bet. You’ll have 7 ft waves from the west with a gentle cross-offshore breeze, making for clean conditions. The energy is moderate (818) and it’s a good, surfable option to get wet.
Keep an eye on the very end of the run, too. The morning of Sunday the 27th is showing a huge 15 ft from the west with a long 12-second period. That’s massive, and the energy reading is through the roof (5553). It's a serious swell, but it's also a long way out, so treat it as a promising but less certain prospect. If it cleans up, it could be epic, but that’s for the big-wave crew only.
For the rest, there are a few other mornings with clean conditions and smaller, weaker swell – like the 25th – but they don’t have the same punch. The water temperature is about average for this time of year, but you'll want a good 3/2 wetsuit.

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.
