The Lowdown
Alright, grab your board. Rusty here with the scoop on The Peak for the next couple of weeks. This reef needs a proper west swell to light up, and we've got a slow burn before it gets good.
Water temp is 61°, a touch warmer than normal for the season.
Sunday the 13th is a dud. Small 3-foot swell from the WNW, messy cross-off wind, and weak energy (186). Not worth the paddle.
Monday the 14th is tiny. Morning has 2-foot swell with a short 8-second period. Afternoon bumps to 3-foot from the west with a better 11-second period and energy at 195, but the wind is still a problem.
Tuesday the 15th is blown out. Swell hits 5 feet, but a strong cross-onshore WNW wind at 18 mph makes it a lumpy mess. Energy is up at 469, but it's not for paddling.
Wednesday the 16th is still poor. 6-foot swell from the WNW with an 11-second period and energy at 672, but it's cross-onshore and messy.
Thursday the 17th is big and ugly. Swell is 10 to 12 feet from the west-northwest with a long 13-second period, and energy goes ballistic at 4576. But it's howling cross-onshore at 25 mph. Expert-only, borderline unsurfable. Kite surfers might love it.
Friday the 18th is the first standout. Morning is a bit messy with 8-foot swell, but by afternoon the wind swings to the SSW at 9 mph, becoming a clean cross-off. Swell drops to 7 feet from the WNW with a solid 12-second period and strong energy at 1200. Excellent surf for experienced surfers. The Peak will be handling that groundswell perfectly.
Saturday the 19th is a step back with onshore wind and 5-5-foot choppy swell.
Sunday the 20th is another big day. 10-foot west-northwest swell with a very long 14-second period and energy at 3213. Wind is light cross-onshore, so it's cleaner than Thursday. For experts only.
Monday the 21st morning is the second standout. Swell is 6 feet from the WNW with a 12-second period, energy at 1051, and a light cross-off wind from the SSW at 6 mph. Clean and excellent for experienced surfers. The afternoon goes downhill.
Tuesday the 22nd and Wednesday the 23rd see the swell drop. Wednesday morning has 7 feet from the WNW, but a short 8-second period and glassy wind. It'll look clean, but be a bit weak.
From Thursday the 24th onward, the swell fades. We're looking at 4 feet and under for the rest of the period, with clean offshore winds at times. A tiny 1-foot bump on the 25th with a 15-second period isn't worth the drive.
Bottom line: Friday afternoon the 18th and Monday morning the 21st are your best bets. Clean, cross-off winds with a solid, long-period west-northwest swell for the experienced crew. The Peak will be on.
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.
