The Lowdown

Alright folks, Rusty here. Let’s have a look at what The Peak has in store for us. This is a reef set-up that loves a west in the swell window, and we’ve got a bit of a mixed bag over the next couple of weeks.

We’ve got a bit of a slow start, to be honest. The first real sniff of anything worthwhile kicks off this Friday afternoon, the 11th of September. The Peak will be seeing a clean 4ft swell rolling in from the WNW at 9 seconds. The water is sitting at 61°, which is a touch warmer than normal for this time of year. That light SSW cross-off breeze will have the waves looking tidy. It’s not huge, but it’s a nice little warm-up.

Saturday the 12th is a write-off. The wind swings around and gets messy, with a choppy 7ft swell that’s just not going to cooperate. Sunday morning the 13th looks better. The wind drops right out to a slight air, swinging cross-off from the SSE. The waves will be small, around 4ft from the WNW with an 11-second period, but it’ll be clean. Good for a longboard or a grovel session.

The middle of next week is pretty bleak. From Monday the 14th right through to the 20th, the wind is mostly onshore and lumpy, or the swell is just too junky. There’s a lot of cross-on wind and rain showers in the mix. The energy gets strong at times – we’re talking combined energy values over 1000 (moderate) and even up to 1532 (strong) on the 17th – but the quality is just not there for a good paddle. It might be more interesting for the kite crew during that stretch.

Now, here’s where it gets interesting. The standout period is Sunday the 20th of September. The morning session is the pick. We’ve got a clean 6ft groundswell from the WNW with a very long 13-second period. The wind is a gentle cross-off from the SSW, so those lines should be holding up nicely. The combined energy is a solid 998 (moderate), meaning there’s some real grunt behind it. This is a reef break, and that long period will make for some nice, walled-up waves. The crowds here are sometimes an issue, so get in early. This is the one to circle on the calendar.

There’s another promising window on Tuesday the 22nd of September. The morning looks clean again with a cross-off breeze and a 5ft swell from the west at 11 seconds. It’s not as big as Sunday, but it’ll be fun.

And then, hold onto your boards for Thursday the 24th of September. This is for the experienced crew only. The forecast is showing a massive 13ft swell from the west, with a very long 15-second period. The combined energy is an enormous 7169 (very strong). The wind is light and cross-off from the south. This is expert territory. The size and the period will make it incredibly powerful, and likely breaking too straight for the beach break, but on this reef, it could offer some absolute bombs for those with the skill and the nerve. Just be aware of the crowd factor if it’s working.

After that, things taper off again through the end of the month, with some onshore wind and smaller swell.

So, to wrap it up: Sunday the 20th is your best bet for a clean, solid session that suits most. Thursday the 24th is the one for the big-wave chargers, but it’s a long way 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.
