The Lowdown
G’day, I’m Rusty. Let’s have a look at what we’ve got coming up at The Peak. It’s a reef setup, fairly consistent, and it really likes swell from the west. The water temp is about average for this time of year, nothing wild there.
Right now, things are pretty messy. Tuesday morning’s got a 4ft west swell but it’s on a short 8-second period and the wind’s a 16 mph cross from the southwest – just poor conditions really, with moderate wave energy (212). That afternoon stays grim with rain and a cross-onshore chop.
Wednesday morning is worth a tiny mention: we drop to 2ft west swell, but the wind swings offshore from the east-southeast at 9 mph, so it’ll be clean. It’s small and ordinary, but at least you can paddle out without getting thrashed. Energy is weak (57). The afternoon goes back to a cross-shore mess.
Thursday and Friday look rough. Thursday morning has a 4ft west swell with moderate energy (124), but that 16 mph cross-southwest wind ruins it. Then Friday… we get a 10ft west swell at 12 seconds, but it’s hammered by a 28 mph cross-onshore wind. Energy is huge (2722), but it’s one for the kite crew, not paddle surfers. Saturday’s swell drops back to 5ft but the wind is still cross.
Now, Sunday the 7th is a write-off, Monday the 8th into Tuesday the 9th shows a bit of life. Monday morning has a 7ft west swell, 10-second period, moderate energy (881), and the wind is cross-off from the south at 12 mph – clean, but a little on the bigger side for beginners. Tuesday morning the 9th is the closest we get to a standout: 7ft west-northwest swell, 10 seconds, and the wind goes light onshore from the northwest at 3 mph. Energy is strong (904). It’s marginal with the onshore, but if you’re an experienced surfer, that window Tuesday morning could give you some grunt.
After that, the second week drops right off. From Thursday the 11th through to the 16th, we’re looking at tiny surf – mostly 1ft to 2ft – with a few clean moments. Monday the 14th has a small 3ft west swell but with a long 13-second period and clean light winds from the south-southwest. It’s a long-period groundswell, so at a reef like The Peak, it could shape up nice, just small. Energy is moderate (259). Not a standout, but the cleanest wave of that whole second week.
Best on offer: Tuesday the 9th morning for size if you’re an expert, or Monday the 14th morning for a clean, small, long-period session.
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.
