The Lowdown
Imperial Version
Alright, Rusty here. Let's have a look at what's cooking. For the first little while, things are pretty flat and average, but there's a promise of some serious grunt later on if you're patient.
We've got one spot that's worth talking about, The Peak. It's a reef setup, fairly consistent, exposed to the west and northwest, and the optimum swell direction is from the west. Perfect setup for the action to come.
For the first week or so, it's a slow grind. From Monday the 24th through to the start of September, the swell is small, mostly below 3ft, and the wind is often cross-off or cross-shore, which keeps things messy. The combined swell energy of all swells directed here is low, often under 100, which is just weak. There's a little window on Monday the 24th with a clean 3ft swell from the WNW, period 11 seconds and a light offshore ESE breeze—that's a nice combo for The Peak, clean and fun. A couple of other afternoons, like Saturday the 29th, turn glassy, but the swell is tiny at 2ft and ordinary.
Then, from the 2nd of September, things start to wake up. On the morning of Wednesday the 2nd, we get a 4ft swell from the west, period 9 seconds, with clean cross-off wind from the SSE and combined energy of 214—moderate energy. It's still a bit marginal though.
But the real standout? That's got to be Thursday the 3rd of September. The morning session sees a solid 8ft swell from the WNW, period 10 seconds, with a gentle SSW cross-off breeze—clean. The combined energy is a powerful 1260, that's strong wave energy. This is proper groundswell energy. The crowd factor is listed as "sometimes," which means it could get a bit busy, but for an 8ft clean swell at a reefbreak like The Peak, that's the main event. It's getting big, over 8ft, so this is for experienced surfers only. Beginners should steer clear.
The action doesn't stop. Sunday the 6th of September brings a very long-period 5ft to 5ft swell from the west, with a period of 18 seconds. That's a serious groundswell, and the combined energy is 1426 in the morning and 1679 in the afternoon—very strong. The wind is light, though it's cross-on in the afternoon, which puts a few ripples on it. A long-period west swell at a reef like The Peak, with an optimum direction west, is a classic combo. Expect clean, powerful lines, and with that period, long waits between sets, but the shape will be proper.
Then Monday the 7th of September morning delivers another standout: 8ft from the west, period 14 seconds, and the combined energy is a massive 2816. Winds are a clean cross-off from the SSE. That's a heavy, powerful swell. Again, this is expert territory. The afternoon stays clean but the southerly wind picks up to 30 km/h (19 mph), which will make it a battle, but the wave quality will still be there for the chargers.
So, to sum it up: the first week is a write-off for serious surf, with a fleeting clean window on the 24th. The real show starts from the 3rd of September onwards, with Thursday the 3rd and Monday the 7th being the absolute standouts for experienced surfers. The Peak is the place to be.
Stay safe out there.
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.
