The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.
Right off the bat, I gotta be straight with you – it’s gonna be a tough slog. We’ve got a long stretch of poor conditions ahead before we see anything worth getting excited about. The main swell direction is out of the west, which is fine for The Peak, a reef break that’s fairly consistent but can get crowded sometimes. The water temperature is sitting at 61°, which is a touch warmer than normal for this time of year, so you won’t need the thickest wetsuit.
The first real standout is a bit of a mixed bag, but it’s the best we’ve got early on. Monday morning, August 10th, brings a glassy session at The Peak. The swell is small, only 3ft from the west-northwest, with a short period of 8 seconds. The wind is glassy, so the surface will be clean as a whistle. Combined swell energy is weak at 90, so it’s not going to be powerful, but for a quick paddle on a tiny board, it’s your best bet. The crowd is possible, so you might have to share.
Now, the gap. After that Monday morning, it’s pretty much dead or messy for days. Tuesday through to the following Monday are all poor surf conditions, with tiny waves and messy winds. You’ll see a little bump on Thursday morning, August 13th, with 2ft from the west and a 10-second period, and the energy picks up to 102 (moderate), but the wind is cross-offshore and it’s labelled as “surfable but very ordinary.” Not worth rushing out for.
We don’t see any real action again until Wednesday, August 19th. The swell starts to build, but the wind is a fresh cross-onshore at 19 mph, making it choppy and lumpy. The swell hits 6ft from the west on Wednesday afternoon, with a 9-second period, and the combined energy jumps to 533 (strong). But honestly, the wind is so bad it’s going to be a mess. This is a beach-and-reef setup, and with that much wind, it might be more interesting for the kite surfers than us paddle surfers.
The biggest swell of the window hits on Thursday, August 20th. The morning shows 7ft from the west-northwest, with a 10-second period, and the combined energy is a whopping 833 (very strong). That’s a lot of water moving. But the wind is onshore from the northwest at 12 mph, so it’s going to be blown out. This is expert territory – 7ft is too big for beginners, and the conditions will be poor. The afternoon is similar, 6ft, still cross-onshore and choppy. So, while there’s size, it’s not clean.
The final glimmer comes on Friday, August 21st, morning. Swell drops to 4ft from the west-northwest, 9-second period, and the energy is 193 (moderate). The wind is onshore from the northwest at 9 mph, so it’s still not great. The afternoon is even smaller, 3ft. After that, it fades back to tiny, messy stuff right through to the end of the forecast on Sunday, August 23rd.
So, the one true standout? If you have to pick a session, make it that Monday morning, August 10th. It’s small, clean, and glassy. Everything else is a write-off or a messy, windy mess. The long-range stuff (August 19th and 20th) has size, but the wind is rubbish, so treat that as a promising but less certain hope. For now, keep your board in the car and wait for a better window.
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.
