The Lowdown
Alright, let’s get into it. This is Rusty, and I’m looking straight at the charts for The Peak.
Right now, the immediate days ahead are a write-off. It’s ugly. The wind is howling from the wrong angles and the swell is all over the place, so stay on the beach for Monday through Thursday. You’ve got strong cross-onshore winds, rain showers, and lumpy, messy conditions. Total energy is weak to moderate (60 to 4438), but it’s not surfable because of the wind.
Now, after that rough patch, things start to turn around. Friday the 18th morning is the first real glimmer of hope. The wind goes light cross-off from the SSW at 12 mph, and you get a solid 8 ft W groundswell pushing in with a 13-second period. The energy is strong (2440) and the surf is clean – this is one for experienced surfers only, but it’s the first good session in the window.
From there, the weekend is messy again with fresh cross-onshore winds, but hold onto your board because the standout arrives on Tuesday the 22nd. Tuesday morning is absolutely mint. The swell pumps at 16 ft from the west with a 13-second period, and the wind is glassy (east at 3 mph). The energy reading is a massive 7302 – that’s pumping. It’s exceptional for experts, and the crowd factor… well, it’s The Peak, so expect it to be busy when it’s this good.
Tuesday afternoon stays glassy, dropping to 12 ft but still clean and excellent for experienced surfers.
After that, you get a few cleaner days into the 23rd and 24th, with lighter winds and glassy conditions. The swell is smaller on the 23rd (4 ft WNW), but it’s clean, so good for a wider range of surfers. Thursday the 24th sees another pulse of longer-period groundswell (16 seconds) at 8 ft from the west, with glassy conditions and exceptional quality for experienced surfers.
By the following weekend (the 27th and 28th), the swell backs right off, and the energy drops below 100. It’s surfable but nothing to write home about, with short 8-second windswell and moderate offshore breezes.
All in all, the two big standouts are Friday morning the 18th – windy but clean with a long-period groundswell – and Tuesday the 22nd – glassy, big, and powerful. That Tuesday session is the one you circle on the calendar.
That’s the picture from here. Get out there when it’s clean.

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.
