The Lowdown
This is Rusty, and here's the word on The Peak for the next couple of weeks.
It starts quiet, and we're looking at a long, dry spell before anything worth paddling out for shows up. The first real chance won't roll in until Sunday, September 21st, so plan accordingly.
The window opens the morning of Sunday the 21st at The Peak. It won't be huge, but a clean 5ft swell from the WNW with a 12-second period is on the cards. A gentle cross-offshore breeze from the SSW will keep things tidy. The combined wave energy sits at 800, so it's got some push. That direction and period should be a good match for this reef. Water temp is about 61°, which is a touch warmer than usual for this time of year. This is your target session—make it count.
Monday the 21st into the 22nd keeps the quality up. Monday afternoon sees a glassy, clean 5ft swell from the WNW as the wind goes offshore out of the SE. Clean, lined-up waves. The energy drops to 633, but the quality will be there. Tuesday the 22nd morning is more of the same, with a light 5ft swell and light winds.
From Wednesday the 23rd, the swell tapers off fast, dropping below 3ft. The wind stays light and offshore through the 25th, but the waves lose all their power—the energy readings get weak, down in the low double digits. It'll be small and limp, good for a log but nothing else. By the weekend of the 27th, there's barely a ripple at 0.6ft.
So here's the deal: sit tight through the crap weather, and be ready for that golden stretch from Sunday the 21st through Tuesday the 22nd of September. That's your window.
Catch ya in the water,
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.
