The Lowdown
Alright folks, Rusty here. Let’s have a look at the next few weeks at The Peak. Honestly, it’s a bit of a slow burn to start. We’ve got a real dry spell before anything worth paddling out for shows up. The first week or so is mostly small, weak, and messy, but there’s a light at the end of the tunnel if you’re patient.
The early days are pretty grim. Friday the 28th through the weekend, we’re looking at tiny 0.7ft to 1.0ft dribble with periods barely reaching 8 seconds. The combined energy is laughable, just 12 down to 8, so there’s no push. There’s a glassy moment Friday morning, but even then, the swell is so weak it’s not worth suiting up. Sunday afternoon sees a little bump to 2ft from the west with a 9-second period, and the energy climbs to 63, but it’s still very ordinary. Not a good start.
Monday the 31st and Tuesday the 1st of September bring a bit more size, around 3ft to 5ft, but the wind is a mess. Westerly cross-on winds at 15 mph on Monday chop it all up, and the period drops to 6-7 seconds. The energy gets into the hundreds (226 and 132), but it’s just lumpy, choppy, and poor. Tuesday morning cleans up a little with a cross-off breeze, but the waves are still marginal.
The real problem here is the lack of clean swell. We get a pulse of energy on Wednesday the 3rd of September that looks promising on paper. Thursday morning the 3rd has a solid 6ft from the west with an 11-second period, and the combined energy jumps to 819 (moderate wave energy). The wind is light and cross-off from the south-southwest, so it’s clean. This is the standout of the whole outlook. The Peak is a reef break, so that longer period groundswell will wrap in nicely, and with light offshore winds, it’s going to be pretty good. The only catch? The afternoon turns nasty with a 10ft west swell and a 13-second period, but the wind swings onshore at 15 mph, turning it into a churning mess. That morning window is the one to chase.
After that, Friday the 4th through to the 12th is a write-off. The swell stays big, 4ft to 8ft, but the wind is almost always cross-on from the west or west-southwest at 12-18 mph, turning the waves into lumpy, choppy junk. The energy is high, sometimes over 2000, but it’s all wind-affected and poor. Crowds are sometimes an issue at The Peak, but with conditions this rough, it’ll be quiet. The later days, like the 9th and 10th, drop back to tiny 0.7ft to 3ft, and the period is short again. The last few days of the outlook have some energy, but the wind is fresh and onshore, so it’s not surfable.
The water temperature is currently 62°, which is 4° warmer than normal for this time of year. That’s notably warm, so you might get away with a thinner suit.
The bottom line: Thursday the 3rd of September morning is the only real highlight. Everything else is either too small, too windy, or too messy. If you’re desperate, there are some tiny, clean moments, but nothing to get excited about.
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.
