The Lowdown
Alright, let’s get into it. Rusty here.
First off, I’ll be straight with you: this 16-day stretch is a tough one. The Peak is the only spot on the radar, and honestly, it’s a struggle. For the first week and a half, we’re looking at a real flat spell with poor, messy conditions. The ocean’s just not giving us much love.
The water’s sitting at a very warm 65°F right now – that’s 7°F above what’s normal for this time of year, so it’s feeling more like a summer bath than a typical July surf. That’s a standout in itself.
We kick off Monday, the 20th of July, with tiny waves around 1ft from the west, with a period of 11 seconds. The swell energy is weak (44). Wind is offshore but light, so the surface is clean, but there’s just no size or power. Tuesday and Wednesday are more of the same – 1ft to 1ft, short period, and poor conditions. It’s a flat, frustrating start.
Thursday the 23rd sees the swell drop even further – 1ft and a period of only 6 seconds. The energy is tiny (11). Cross-onshore winds are making it choppy and messy. Not worth paddling out.
Friday the 24th finally shows a pulse: the swell bumps up to 4ft from the west-northwest, with a 9-second period. The energy jumps to moderate (202), but the wind is cross-onshore and choppy. The surf is still rated poor. It’s a tease.
Saturday the 25th and Sunday the 26th bring the biggest swell of the whole outlook – 6ft (Saturday morning) and 6ft (Sunday morning) from the west-northwest, with periods around 10 seconds. The energy is strong (637 and 466). This is the most size we’ll see, but it comes with a catch: moderate to fresh cross-onshore wind, and the conditions are choppy and messy. For a reef break like The Peak, that’s a serious letdown. Too big for beginners, and the wind is ruining the shape. The surf quality is still poor.
Monday the 27th through Wednesday the 29th hang around 5ft to 6ft, still with moderate energy (377 to 556), but the wind stays cross-onshore or cross-shore, keeping things lumpy and unattractive. Wednesday the 29th afternoon sees a fresh breeze of 19 mph from the west-southwest – that’s fresh cross-onshore and lumpy. Not a good look.
Thursday the 30th drops to 3ft from the west-northwest, with a period of 8 seconds (147 energy). The wind is lighter, but the conditions are still poor.
Then, finally, on Friday the 31st of July, we get a real moment of hope. The morning shows clear skies, a light offshore breeze from the southeast at 3 mph, and clean conditions. The swell is small – 2ft from the west, with an 8-second period – but the energy is weak (47). The water is clean, but there’s just not enough push to get excited. It’s surfable but very ordinary.
Saturday the 1st of August is the best of a bad bunch. Morning: 2ft from the west, 9-second period (73 energy), with a light cross-offshore breeze from the east-southeast at 6 mph, and the conditions are clean. Afternoon: 2ft, 9-second period (67 energy), with a gentle offshore from the southeast at 9 mph. The wind is offshore, the surface is clean, and the waves are literally surfable. It’s small, but it’s the cleanest, most rideable window in the whole 16 days. If you’re desperate, that’s your moment.
From Sunday the 2nd onward, it’s back to small, weak, and messy. The final days show a few pulses of energy (up to 143 on Monday the 3rd, and 265 on Tuesday the 4th), but the wind is cross-onshore and lumpy, and the surf quality is rated poor. The 4th of August has a fresh cross-shore wind of 19 mph, making it lumpy and unappealing.
The standout: There’s no true standout here. The best window is Saturday the 1st of August – small, clean, offshore winds – but it’s for the patient surfer on a longboard or a foiler. The biggest swell is on the 25th and 26th of July, but the wind kills it.
One caveat: The Peak is a reef break, and it’s fairly consistent, but with this forecast, it’s a long wait for something worthwhile. Forecasts can change, so don’t lose all hope.

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.
