The Lowdown
Alright, surfers, Rusty here with the full 16-day scoop for The Peak.
We’re looking at a reef break that’s fairly consistent and exposed to a west swell. Water temp is about 62°, which is 4° above normal – much warmer than what we usually see this time of year. But don’t let that fool you; the first week is a real grind.
Starting Saturday August 29 through the end of the month, it’s tiny. Saturday morning sees flat 0.7ft from the west with only 7 seconds of period and basically no energy (7). Glasy conditions, sure, but it’s a lake. Sunday morning gets a whiff of offshore SE wind and a little more push – 1ft west at10 seconds, energy still weak (39) – but it’s still too small to ride. Afternoon goes cross-on and bumpy.
Monday August 31 sees a bit more size, 5ft west-northwest, but the period drops back to 8 seconds and the wind is cross-onshore at 16 mph, making it choppy. Moderate energy (270) but messy. Same story Tuesday September 1 – 5ft WSW swell, cross-off wind, clean-ish but only marginal, energy 304. Not worth paddling out.
Wednesday September 2 has a tiny glassy window in the morning: 2ft west, period 8 seconds, energy 70 (weak),and the wind goes glassy. Surfable but very ordinary. Then the wind swings and it’s back to cross-chop by afternoon.
Thursday September 3 gets a bit pumped up – 7ft west at8 seconds, but the wind is howling 19 mph cross-onshore, energy 559 (strong but lumpy). Poor. Friday September 4 cranks a12ft west swell at13 seconds – that’s a lot of energy (3829) – but the wind is onshore at 22 mph. Too big, too blown out. Honestly, this setup looks more interesting for kite surfing than paddle surfing.
Now here’s the standout – Monday September 7 morning. The swell settles to 5ft from the west at9 seconds, combined energy 417 (moderate). The wind goes glassy from the south at3 mph. Clean face, good shape, and conditions are labelled “expect good surf conditions.” That’s your window. Crowds are sometimes, so you might share it, but it’ll be worth the paddle. The afternoon gets a light cross-on, so morning is the call.
After that, it’s back to poor. Tuesday September 8 onshore, Wednesday September9 morning has a clean offshore (SE 9 mph) but the swell drops to3ft west-northwest at8 seconds, energy 95 (weak) – surfable but ordinary. Then the rest of the window fades into lumpy, onshore wind and small surf.
Bottom line: one solid session on September 7 morning. The rest is either too small, too windy, or both. Keep that date in mind and don’t expect much else.
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.
