The Lowdown
Right, listen up. Rusty here. Gotta say, the next couple of weeks are a bit of a mixed bag. We're looking at a long stretch of ordinary to poor conditions at The Peak, but there is a light at the end of the tunnel. The first week is pretty much a write-off, but if you can wait, the second week has a couple of windows that'll make it worth hanging in there.
The first bit of surf worth mentioning is on Wednesday morning, 2nd September. The swell is only 2ft, but it's coming from the west with an 8-second period, and we've got a light SE offshore breeze. The combined energy is weak (57). It's surfable, but honestly, it's pretty ordinary. You'll be fighting for scraps.
The next real glimmer doesn't come until Monday, 14th September. That's a long wait of nearly two weeks. That morning, we've got a clean 5ft west swell with a 9-second period, and light offshore winds from the ESE. The energy is moderate (401). That afternoon, it gets serious. The swell jumps to 8ft from the west, period stretches to 11 seconds, and the wind stays offshore from the SSE. The combined energy is strong (1656). This is the standout. For experienced surfers, this is going to be excellent. Just be aware, with that size and period, it'll be a lot of wave, so it's not for the faint-hearted.
Tuesday, 15th September, is still good. The morning holds a clean 7ft west-northwest swell with light winds, and energy is still strong (850). The afternoon eases off a bit to 4ft but stays clean. That's your best run.
The Peak is a reef break, so it's exposed to west swell, which is exactly what we get. The water is 63° and much warmer than normal for this time of year, so you won't need a thick suit. It can get crowded here sometimes, so with the good windows, expect a few locals out.
Don't bother with anything else. The whole first week is a mess of cross-shore winds and rain. The swell on the 8th and 9th of September is huge, over 8ft, but with strong winds and a cross-chop, it's just a washing machine. Even the 16th of September has a massive 8ft swell with a very long 14-second period, but the cross-on wind and marginal conditions mean it's not going to be the clean, organised wave you want, especially as that long period stuff can be tricky at a reef.
If you've got the patience, pencil in the 14th and 15th. That's the call.
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.
