The Lowdown
Right then, let’s have a look at what’s on the cards for The Peak. This is a reef setup that’s exposed to the west, and it’s fairly consistent, so we’ve got a bit to work with. The water’s sitting at 61°, which is a touch warmer than normal for this time of year – you won’t be needing the thickest rubber.
The week kicks off Monday with some small, clean surf. It’s nothing to write home about, with waves around 2ft to 3ft coming from the west. The wind is a light cross-offshore, so it’s rideable but ordinary. Combined energy is low (78 to 195), so you’re looking at a mellow paddle. Tuesday sees a jump in size, but the wind swings onshore and gets strong, hitting 30 km/h. Swell hits 7ft from the west, but it’s messy with a moderate energy (643) – not worth it. Wednesday and Thursday are similar stories; the swell builds but the wind is all wrong. Thursday afternoon is a write-off with an 12ft west-northwest swell and a 14-second period, but a strong cross-onshore wind at 40 km/h makes it a total mess. The energy is huge (4420), but that’s for the wind, not for paddling. That setup looks more interesting for kite surfing than paddle surfing.
Friday morning brings a bit of relief. The wind shifts to a cross-offshore, and we’ve got a solid 8ft west-northwest swell with a 13-second period. It’s clean, and the energy is strong (2028), but the conditions are still marginal – it’s one for the experienced crew only. Saturday drops back into onshore wind and lumpy surf.
Now, here’s the standout. Sunday the 20th is where it’s at. Morning brings offshore wind from the southeast at just 10 km/h, with a clean 6ft west-northwest swell. The period is a nice 12 seconds, and the energy is solid (992). This is your pick of the week – clean, lined-up waves and you won’t be fighting the wind. Crowds are sometimes an issue here, so get in early. After that, Monday the 21st keeps the clean theme with a lighter 4ft swell from the same direction, but still good fun. The rest of the second week drops back to smaller, cleaner but less powerful waves, with the 24th Thursday morning offering another clean 6ft west-northwest swell (791 energy) and light winds – another good shout for a paddle.
Overall, Sunday the 20th morning is the clear winner. Get on it.

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.
