The Lowdown
G’day, Rusty here. Look, I’ve been staring at the charts, and I’ll be straight with you: there’s almost nothing to get excited about on the horizon. We’ve got a solid run of poor surf stretching out for the next couple of weeks, and the only break with any kind of pulse, The Peak, a reef setup exposed to the west, is going to be fighting the elements the whole way.
For the first week, it’s a dead loss. The swell is tiny, and the wind is mostly onshore or cross-onshore, leaving the ocean messy and weak. The water is a warm 63°F, which is running about 4°F above the norm for this time of year, so you’ll feel that warmth, but the waves won't be doing you any favors. The combined energy is weak, hardly getting into the low 80s, so there’s just nothing behind those dribblers.
We do see a slight pickup on Tuesday and Wednesday, the 18th and 19th, with swell climbing to around 4 feet and energy jumping up into the 400s. But just as it gets going, that fresh westerly wind kicks in, blowing cross-onshore and turning the place into a lumpy, choppy mess. Thursday the 20th holds some size, around 5 feet from the WNW, but the morning onshore wind ruins it again. The period is short, only 8 to 10 seconds, so those waves are just weak and crumbly.
Then it just dies. From Friday the 21st right through to the 28th, we’re in a massive, dry spell. Swell heights drop below 2 feet, the period shrinks, and the energy readings are pitiful, often in the single digits. You get the odd clean morning with light offshore or even glassy conditions, like Sunday the 16th or Wednesday the 26th, but there’s literally nothing breaking.
So, if you’re really scratching for something, look to the very end of the window. Sunday the 30th sees a bump back up to around 3 feet from the WNW, but the period is still short at 7 seconds, and the wind is cross-onshore again. It’s not good, but it’s the only pulse on the board. The Peak will only show its true quality if the swell direction aligns with its preferred W, and this week’s weak, short-period energy isn't doing it any favors. This looks like a normal blank run for this coast. Forecasts can change, but as of now, get ready for a long stretch of flat, blown-out conditions.
Rusty, signing off.

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.
