The Lowdown
Alright, Rusty here, let’s talk about what’s on offer.
We’ve only got one spot in the mix this time: The Peak. It’s a reef break, pretty consistent, and it needs a west swell to really get going. The water’s running at 62° right now, which is a solid 4° warmer than usual for this time of year – that’s a real treat, feels more like summer than early autumn.
The first few days are a write-off, I’m sorry to say. Wednesday morning through Friday morning are all poor – the wind is messy, cross-on, chop is up, and the energy is all over the place. We’re looking at combined swell energy around 213 to 239 (moderate), but the quality just isn’t there. Friday afternoon things shift a little – a light cross-off breeze and clean conditions roll in, with a 4 ft swell from the WNW, period at 9 seconds. The energy jumps to 327 (moderate), and it’s surfable, but the real standout for the first week is Sunday morning the 13th.
Sunday morning is clear, light SSW cross-off wind, 4 ft of WNW swell with an 11-second period, giving it some real push. The combined energy is 302 (moderate), and the waves are clean. It’s not giant, but the conditions are right – that’s the best we’ve got in the first week. The Peak is a reef, so it’ll handle that period well. Crowds are possible here, so keep an eye out.
After that, we hit a bit of a lull. Monday and Tuesday still have some clean morning windows, but the swell drops and the energy gets weak – we’re talking 83 to 238 (weak to moderate). Nothing to get excited about.
Now, the second week has a couple of promising calls. The first real standout is Friday morning the 18th. We’ve got a solid 5 ft WNW swell, period stretching to 12 seconds, and a gentle offshore from the SSE keeping things clean. Combined energy is 768 (strong). That’s a proper groundswell with shape, and at The Peak with light offshore winds, it’s going to be quality. The afternoon holds up, too, with a clean cross-off and 5 ft, but the morning is your best bet.
Then Monday morning the 21st is another one to circle. Light offshore from the ESE, 4 ft WNW swell with a 12-second period, combined energy of 519 (strong). Clean conditions, no wind to speak of – glassy. That’s a good session.
The biggest call of the whole forecast lands on Tuesday morning the 22nd: a 6 ft swell from the west, 10-second period, offshores from the SE, and combined energy of 633 (strong). That’s a solid, powerful wave, and it’s clean. For the more experienced crew, that’s the one to aim for. The afternoon gets messy with cross-on wind, so get out early.
The last week looks a bit more mixed. The 24th has a 6 ft to 7 ft WNW swell with a 12-second period, and energy up to 1316 (very strong), but the wind is either cross-off or cross-on, and the conditions are marginal. That’s a big swell – over 8 ft – so it’s expert-only territory, and even then, the wind is not ideal. Might be one for the thrill-seekers, but it’s not the cleanest.
So, if you’re picking your sessions: Sunday morning the 13th for the first week, and Friday morning the 18th or Tuesday morning the 22nd for the second week. Those are the standouts.
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.
