The Lowdown
Alright, let's get into it. The start of this period is a total dead zone for The Peak. We're looking at a week-long drought with poor surf conditions across the board. Tiny, weak swell and messy winds. It's not worth getting wet for. The waves are small, the wind is all over the place, and you'd just be fighting it. Hang loose, this one's a test of patience.
The first real swell of any consequence arrives on Thursday, September 4th. The morning brings a big 10ft west swell with a strong 12-second period. The combined energy is pumping at 2468, which is serious juice. But this is a reef, exposed to the west, and the morning light cross-shore wind keeps it marginal. The afternoon just gets bigger, hitting 12ft, but the onshore wind is going to wreck it. This is big, heavy surf for serious surfers only, and the conditions are going to be messy.
The day to actually clear your schedule is the morning of Friday, September 5th. The swell eases down to a much more user-friendly 6ft, still with a solid 10-second period and that good west direction. The energy is still strong at 682. The wind is light from the southwest, which is okay, but then the afternoon turns glassy. The swell drops to 5ft, and it's completely clean. This is the standout. The Peak with that west groundswell and clean conditions is going to be firing. It'll be popular, but it's a reef that handles a crowd. This is the one you want.
After that, the window slams shut. The last week of the forecast sees the surf dropping back down, with fresh winds and onshore slop making a comeback. There are a few cleaner moments, like the 6th with that offshore wind, but the size drops off and it gets jumbled. By the 10th and 11th, we're back to tiny, onshore junk.
One other thing to note: the water is running at about 62°F at the start of this stretch, which is over 4°F warmer than the long-term average. That's noticeably warm for this time of year.
So, there you have it. A long, barren start, one absolute gem of a session on the 5th of September, and then it fades back into nothing. Keep your eyes on that one day.

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.
