The Lowdown
Hey, Rusty here again. Let’s break down the same stretch for The Peak, but in feet and miles per hour, the way some of you like it.
First real chance to surf ain’t until Thursday the 10th. The start of the week is a total loss. Sunday the 6th shows 2ft from the west, but with a 30 mph south wind, it’s just junk. Monday and Tuesday get bigger – Tuesday hits 11ft from the WNW – but it’s cross-on with winds over 40 mph. That setup at that size is pure kite-surf stuff, not paddle surfing. We’re in a holding pattern.
Thursday morning the 10th, it’s finally surfable. Swell is tiny at 2ft from the west with a short 8-second gap, combined energy is weak at 67. But the wind is light at 10 mph from the SSE, cross-off and clean. It’s small, but you can get a few little turns on a longboard.
The real standout is Saturday the 12th. Morning looks unreal. We’ve got 5ft of swell from the WNW, and that period jumps to 13 seconds – proper groundswell with decent energy (732). The wind is a light 15 mph from the SSE, cross-off and clean. This is the best session of the whole run. The Peak is an exposed reef, and that long-period groundswell will groom into some nice lines. Crowds are possible here when it’s on, so get out early.
Sunday the 13th holds 5ft from the WNW, 12 seconds (658 energy), but the morning wind is a fresh 30 mph from the south. It’s cross-off and clean, but that wind is strong enough to make it a battle.
Then Monday afternoon the 14th steps up. Swell is 5ft from the west, 11 seconds, and the wind goes light at 15 mph from the SSW, cross-off and glassy. Expect very good conditions. That afternoon is a gem.
Thursday the 17th is another winner. Morning delivers 5ft from the west, 11 seconds (599 energy), with a light 10 mph SSW breeze, cross-off and clean. The afternoon gets even better – pure offshore wind from the SSE at 10 mph, with 5ft west swell, 11 seconds. That afternoon will be a picture.
Saturday the 19th is solid, too: 4ft from the west, 10 seconds, with a gentle 15 mph SSW cross-off.
But the absolute best of the outlook is Sunday the 20th. Morning session: 6ft of swell from the west, 11-second period, combined energy at 792. Wind is pure offshore from the SE at 15 mph. Gentle offshore and clean. That’s the one to mark on the calendar. The Peak with offshore winds and a solid 6ft west swell is going to be handing out some beautiful, rippable walls. Just be ready for it to be busy.
Water temp is about 62°F, which is roughly 5°F warmer than average for this time of year – that’s a pretty big deal, so the water feels nice.
In short: suffer through the early nonsense, then lock in Saturday the 12th morning, Monday the 14th afternoon, Thursday the 17th, and for sure Sunday the 20th morning.
Stay frothy,
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.
