The Lowdown
Alright, Rusty here. Let’s talk about what’s coming up at The Peak.
Right now, things are flat and pretty grim. The forecast shows a long stretch of hardly any surf to start with. From late August through the first few days of September, we're looking at tiny, weak swell – barely a ripple. The water temp is sitting at 63°F, which is much warmer than normal for this time of year, so at least the paddle out won’t sting.
You’ll see a gap of nearly a week where there’s nothing worth paddling for. The swell is puny, period is short, and the wind is mostly cross or onshore. Not much to get excited about. The first real sign of life doesn’t show up until the tail end of the window.
Now, if you’ve got patience, The Peak (reef break) can start to show its teeth from the morning of September the 4th (Friday). That’s when we get a solid pulse of groundswell rolling in from the WNW. Wave heights around 4ft with a period of 11 seconds – that’s a proper groundswell with good energy behind it (combined energy pushing 400). Winds will be light offshore from the SE, making for clean, lined-up waves. This will be a standout session, especially for a reef break that loves that west-northwest direction. The crowd factor is "sometimes," so you might have some company, but with clean conditions like this, it’s worth it.
The quality holds into September the 5th (Saturday). Still clean and glassy, with a slightly smaller but sweet 3ft to 3ft swell from the same direction, and that light cross-off wind keeping the face smooth. Combined energy is still solid in the 200s. This is the pick of the entire forecast, and it’s consistent enough to keep you smiling all morning.
After that, it fades again. September 6th drops off, and by September 7th and 8th, the wind picks up and the quality goes pear-shaped. The final week is blown out or choppy, with cross-onshore to strong onshores making a mess of things.
So, to sum it up: wait it out through the first week. The best bet is Friday the 4th and Saturday the 5th of September at The Peak. That’s where you want to be.
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.
