The Lowdown
Right, let’s have a look at what we’ve got for The Peak. This is our only real option on the table, and it’s a solid little wave when it lines up. The water is cooking at 63°F, which is a good 5°F above the long-term average for this time of year – that’s notably warm, so pack the boardshorts and maybe a spring suit at most.
The forecast kicks off on Wednesday the 2nd with a small, weak pulse. You’ve got 2ft from the west with a short 8-second period. Combined energy is only 57, so it’s gutless. The morning has a light offshore SE breeze, so it’ll be glassy and clean, but honestly, it’s barely worth paddling out for. The afternoon turns to rubbish with a cross-shore SW wind messing it up.
Thursday the 3rd looks average. Morning is still cross-shore and sloppy with 3ft, and while the afternoon swell bumps to 4ft from the WSW with a slightly better 9-second period and moderate energy (274), the wind is still cross-shore. It’s not terrible, but it’s not good either.
Friday the 4th is a big event, but not for paddling. We get a solid 12ft groundswell from the west with a lovely 12-second period – the energy reading is 4042, so there’s a whole lot of power in the water. But the wind is howling onshore from the WSW at 28 mph. That’s messy, lumpy, and honestly, this setup looks far more interesting for kite surfing than a proper paddle surf. Only the most experienced chargers should even consider it, and even then, it’s going to be brutal.
Saturday the 5th is your standout window, no question. Morning is the pick. You’ve got 5ft from the west with a 10-second period (551 energy), and clean, light cross-off winds from the SSW. That is going to produce some really nice, clean waves at The Peak. The afternoon drops to 4ft but stays clean. If you can get out there Saturday morning, that’s the best of the whole run.
Sunday the 6th is a big drop-off. Tiny 2ft waves with almost no energy (50), so not really worth the effort despite the clean conditions.
The whole of the following week from Monday the 7th through to Friday the 11th is a write-off. We get another big swell pulse – 13ft from the west on Tuesday the 8th with a massive 4293 energy – but it’s locked in with strong onshore winds. Pure chaos and blown-out slop. Then it fades to tiny, weak swell with cross-shore winds.
There’s a significant gap from the 11th right through to the 13th of September with nothing worth paddling for. Then on Sunday the 13th, we get a little glimmer: 4ft from the west at 10 seconds with a clean light cross-off breeze. It’s rideable and clean, but nothing special.
The real last hope is Tuesday the 15th of September. Morning shows 4ft from the WNW with an 11-second period and a light offshore breeze from the ESE – that’s clean. The afternoon gets glassy with a 3ft swell. The energy is moderate (297 and 231) and the winds are perfect. It won’t be pumping, but for a Tuesday afternoon surf, it’ll be smooth and enjoyable without a crowd.
So to wrap it up: your best bet is Saturday the 5th of September, morning session. After that, Tuesday the 15th of September is a decent fallback for a clean, glassy paddle. The rest is either too windy, too small, or just plain messy.

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.
