The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming our way at The Peak.
Right off the bat, the first few days are a bit of a write-off. We’re looking at a slow start with poor to marginal conditions. Wednesday the 9th is a no-go with a messy 4ft cross-on swell from the WNW and a moderate breeze chopping it up. Thursday and Friday aren’t much better – the wind is mostly cross or cross-on, and the waves are either small or messy. Friday afternoon gets a tiny bit of hope with a 4ft swell, but the period is a short 8 seconds and it’s still cross-shore, so it’s barely a ripple.
The first real glimmer comes on Saturday the 12th morning. We’ve got a solid 6ft swell from the WNW with a 13-second period, and the wind is cross-offshore. That’s a clean look, but with combined energy at 1230, it’s a powerful wave. That’s getting into the “too big for beginners” territory. The afternoon turns onshore, so the window is narrow.
Sunday the 13th is a proper winner. The swell drops to a clean 4ft from the WNW, still with a solid 11-second period, and the wind is light and cross-offshore. The combined energy is 366, so it’s got push but it’s not out of control. That’s the pick of the first week for a real surfable session. The water temp is about average for the time of year, so no surprises there.
We get a bit of a lull Monday and Tuesday, with small waves and cross-on winds, but then Wednesday the 16th morning fires up again. A 4ft WNW swell hits with a moderate offshore breeze from the ESE. That’s clean, lined-up waves with a 10-second period. The Peak is a reef, so it handles that direction well. The afternoon picks up to 6ft, but the wind shifts cross-off, so still decent.
Now, the real standout is in the second week. Look at Friday the 18th. The swell jumps to 7ft in the morning with a long 13-second period from the W, combined energy of 1475. That’s a powerful, solid groundswell. The wind is cross-on, which makes it a bit rough, but by the afternoon the wind drops to a light breeze and the swell is 6ft with a 12-second period. The quality is a bit marginal at that size for a reef, but it’s worth a look for the experienced crew.
But the absolute best of the whole run is Wednesday the 23rd. The morning shows a 8ft WNW swell with a 12-second period and combined energy of 1881. That’s expert-only territory. The wind is gentle and cross-offshore, so the face is clean. The afternoon gets even better: 8ft, still 12 seconds, but the wind goes glassy offshore from the SE. That’s an excellent forecast for experienced surfers, with the reef holding the power and the long period making for some serious, deep-water lines. The Peak loves a W to WNW, so this is the one to circle.
The gap between recommendations is just a couple of days early on, then a few days in the middle of the second week. The Peak is fairly consistent, so it won’t stay flat for long.
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.
