The Lowdown
Alright folks, Rusty here. Let’s get into it for The Peak. We’ve got a bit of a rough patch to get through, but there’s a light at the end of the tunnel.
The overall pattern is pretty messy for the first week and a half. The wind is a constant problem, and the swell is mostly all over the place. The Peak is a reef break, which is good, but it’s exposed to the west, and the wind is going to be hammering it from the wrong directions for a while. We’re looking at a serious gap where there’s nothing worth paddling out for.
The water temperature is sitting at 63°, which is a huge 5° above normal for this time of year – that’s a real anomaly, feels like a late summer holdover.
Thursday the 3rd and Friday the 4th are a total write-off. The wind is howling on Friday, 25 mph cross-on, with over 10 ft of messy, wind-blown swell. The wave energy is huge (4068 on Friday morning), but it’s all for nothing. Just a washing machine.
Saturday the 5th is a slight improvement. The swell drops to 5 ft in the morning from the west, and the wind swings to a light cross-off from the SSW. It’s still marginal, and the energy is weak (562), but it’s the first half-decent window. The water is still that warm anomaly.
Sunday the 6th through to Thursday the 11th is a grim stretch. The swell is either too small, the wind is onshore or cross-on, and it’s just lumpy, choppy, and poor. The energy dips to as low as 60 on Sunday afternoon. Don’t even bother.
Now, here’s the standout. The real prize is Saturday the 12th. This is the one to circle on the calendar. The swell is a solid 8 ft in the morning from the WNW, with a nice long period of 13 seconds – that’s proper groundswell. The wind is a clean offshore from the ESE, light breeze, making for glassy conditions. The wave energy is pumping at 1935. This is excellent surf for experienced surfers. The crowd is listed as “sometimes” here, so there might be a few others who’ve been waiting for this window, but it’s worth it. The swell direction matches the optimum perfectly from the west. This is the best on offer.
Sunday the 13th the swell collapses back to under 3 ft, and the wind turns onshore again. The party is over.
Monday the 14th and Tuesday the 15th are pretty average. Tuesday morning has a moment of glassy conditions with a 4 ft WNW swell, but the energy is low (318) and it’s just “expect good surf conditions” – not a standout.
Wednesday the 16th sees a small, clean 3 ft west swell, but it’s surfable, not special.
The last few days, Thursday the 17th and Friday the 18th, get ugly again with strong onshore winds and lumpy, messy conditions. The energy on Friday morning is 1085, but with 19 mph onshore wind, it’s a no-go.
So, bottom line: there’s a massive gap from now until the 12th. The only real, proper standout is Saturday the 12th of September at The Peak – get on it if you can handle a solid 8 ft with offshore winds.

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.
