The Lowdown
Alright, Rusty here. Let's get into it.
Alright, folks, let's be honest, the next couple of weeks are looking pretty grim for a paddle. The Peak is our only real option on the table, and it's copping it. We've got a solid run of onshore and cross-shore winds that are just gonna mash up the swell. The water is sitting at 62°F and that's a solid 4°F warmer than usual for this time of year, so it's not a shock to the system when you get in, but the conditions are a different story.
The first week is a write-off. Monday the 7th kicks off with rain showers and a 22 mph cross-on wind, making a mess of that 7ft W swell. The combined wave energy is moderate at 740, but the wind is the killer. The whole of that first week, right through to Sunday the 13th, is just a battle with onshore or cross-shore breezes. There's a brief moment early on Thursday the 10th with a clean cross-off shore wind and a 3ft W swell, but it's still a pass. The big highlight is Saturday morning the 12th – we get a solid 5ft WNW groundswell with a nice long 13-second period, delivering a strong 828 combined energy. The wind is clean cross-off, so it should be clean. That's the best you're going to get, but it's only a "marginal" call, so don't expect perfection. The Peak is a reef setup, so that long period energy should hold up well, but it's not a classic day. The afternoon of the 12th goes straight back to a fresh 22 mph cross-shore, so get in early.
The second week starts to fade. Sunday the 13th afternoon has a tiny 3ft WNW swell and a slight cross-off wind, but it's just surfable, not exciting. Monday the 14th is another clean morning with a 3ft W swell, but the combined energy is low at 198. The wind is a moderate 12 mph cross-off, so it's clean, but the waves are small. The rest of the week is a mix of small surf and deteriorating winds. Thursday the 17th through Saturday the 19th sees a few mornings with clean conditions and tiny 2ft to 3ft WNW swells, but the energy is weak. It's a long paddling session for a few knee-high bumps.
Then, out of nowhere, we get a spike on Sunday the 20th. A 6ft W swell with a 12-second period hits, but it's wrapped in a 12-16 mph cross-on wind, so it's going to be a choppy, messy mess. The following Monday and Tuesday the 22nd and 23rd look even worse, with a 10ft WNW swell on the Tuesday afternoon being completely blown out by a 28 mph onshore gale. That's a massive 2344 combined energy, but with that wind, it's a full-on washing machine. For kite surfers, that setup on the 22nd would be absolute heaven, but for a paddle surfer, it's a hard pass.
Honestly, your best bet in this whole 16-day window is the Saturday morning the 12th. It's not a world-beater, but it's the cleanest window we've got with some size and power. Everything else is a fight against the wind or a battle with tiny waves.
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.
