The Lowdown
Alright, let’s get into it. The next couple of weeks are looking pretty grim for any sort of proper surf. We’ve got a long stretch of small, wind-blown, and generally messy conditions ahead. Honestly, the first real chance of anything decent doesn’t show up until the back half of next week, and even that’s a bit of a stretch.
Right off the bat, Wednesday the 5th is a total washout. The Peak (Big Island) is getting hammered by a fresh onshore breeze and a lumpy, short-period swell mixing in some rain. It’s just not worth your time. Thursday the 6th is smaller and still chopped up. Friday the 7th has a little pulse in the morning, but it’s still poor, and the afternoon turns into a cross-on mess.
The weekend isn’t offering any salvation. Saturday the 8th is clean-ish in the morning but the waves are tiny and weak. Sunday the 9th is the first time we see a bit more size, but the wind is all over the place. The morning is cross-shore and lumpy, but the afternoon actually cleans up with a cross-off breeze and a 5ft west swell. That’s the best of a bad bunch, but it’s still not great. The wave energy is moderate, around 432, and it’s a short-period swell so it won’t have much punch.
After that, next week is a flat spell. Monday and Tuesday are tiny, with the swell dropping right out. There’s a bit of glassy conditions on Tuesday afternoon, but the swell is only thigh-high. It’s a dead period for a few days.
Then, we finally get a pulse of bigger swell on Thursday the 13th. The afternoon sees the swell jump to 7ft from the west with a 10-second period. The energy is strong, hitting 784, but the wind is cross-on and the conditions are described as marginal. It’s going to be lumpy and bumpy. Friday the 14th morning is glassy with a 4ft west-northwest swell. That might be the most surfable wave of the whole run, but it’s still small. The water temp is about average for this time of year.
The final few days of the window are more of the same—small and messy. There’s another push of energy on the 18th, with a 6ft west-northwest swell, but it’s again plagued by cross-onshore winds. All in all, there are no true standouts here. The only windows that look even remotely clean are Sunday afternoon the 9th and Friday morning the 14th, but both are compromised. This is a period for fixing your board and checking the forecast again in a few days.

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.
