The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s shaking over the next couple of weeks.
Honestly, this is a bit of a tough stretch. The Peak is a reef break that’s exposed to the west and loves a good W swell, but for the first several days, we’re looking at a whole lot of nothing. The surf is small, the energy is weak, and the conditions are mostly messy. You’re looking at a gap of about a week before anything even starts to get interesting.
The first real pulse of energy shows up on the morning of Monday, August 19th. The swell is from the WNW at 5 feet with a period of 10 seconds, and the combined energy jumps to 555 (moderate to strong). That’s a solid pulse of groundswell. The only problem is the wind is going to be a moderate cross-onshore breeze at 12 mph, so it’s going to be choppy. That same setup holds through the afternoon and into the next morning. Not ideal for The Peak, but it’s the biggest swell of the window. The water temp is about average for this time of year, so nothing wild there.
The one standout, if you can call it that, happens on the morning of Saturday, August 22nd. The swell is 4 feet from the west at 9 seconds, and the combined energy is 190 (moderate). The wind is glassy—just a slight air from the NE at 3 mph. That’s going to be clean, smooth, and surfable. It’s not a monster, but for a reef break like The Peak, that’s your best window. The energy is moderate, and the conditions will be glassy with no wind chop. It’s a small, clean day. Crowds are possible here, so keep that in mind.
Before that, there’s a brief window on the afternoon of Monday, August 11th, with a 0.7 feet swell from the W at a very long 13 seconds. That’s a tiny, long-period groundswell, but the energy is weak (22). It’s clean with a cross-offshore breeze, but it’s so small it’s barely worth a paddle.
After that standout Saturday morning, the swell drops off again. The following week is back to small, weak, and onshore winds from the NW. The energy is low, and the conditions are poor. A bit of a flat spell to end the forecast.
Bottom line: The best bet is the morning of August 22nd. Small but glassy. The bigger swell around August 19th has the size but the wind will mess it up. If you’re desperate, head out for that glassy Saturday morning.
Stay salty,
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.
