The Lowdown

Alright folks, Rusty here. Let’s get into it.

The next couple of weeks are a real mixed bag. The Peak is the only spot on the radar, and it’s a reef break that’s exposed to the west swell. Right now, we’re looking at a long stretch of frustratingly small, weak surf with poor conditions, so you’ll need to be patient. The first real glimmer of hope doesn’t show up until early September, and even then, it’s a bit of a tease.

The water temperature is sitting at 62°, which is a solid 4° above the long-term average for this time of year – that’s notably warmer than usual.

We’re starting off with a flat spell. Thursday afternoon (27 August) has a tiny 2ft west swell, but it’s 9-second period, meaning weak energy, and a risk of thunderstorms with a light cross-off breeze. Don’t get your hopes up. Friday and Saturday (28-29 August) are even smaller, with swells barely cracking 1ft or 0.7ft. The energy is just a pittance. Sunday (30 August) shows a slight bump up to 1ft and 2ft, but again, it’s poor surf conditions. The combined energy is still weak. So, we’re looking at a gap of almost no worthwhile surf from Thursday through to the end of August.

Monday (31 August) brings a bit more size – 3ft to 4ft west swell, with a 10-second period. The energy is moderate now, but the wind is all wrong. A cross-onshore breeze from the west is making it lumpy and chopped. Tuesday (1 September) is similar, with 4ft to 5ft swell, but still blown out by fresh cross-onshore wind. Not great.

The first sign of something surfable comes on Wednesday morning (2 September). A small 2ft west-northwest swell with a 9-second period, light offshore wind from the southeast, and clean conditions. The energy is only 51, so it’s weak, but it’s a start. Still, it’s just "surfable" and very ordinary. The rest of that day and Thursday (3 September) are back to poor conditions, with moderate to fresh winds and lumpy surf.

Now, Friday (4 September) is a big one. A 8ft west swell rolling in with a 13-second period – that’s a long-period groundswell, packing a punch. The combined energy is a massive 1862! But here’s the catch: the wind is a fresh cross-onshore from the west-southwest, making it lumpy and messy. That size is only for experienced surfers, and the conditions are far from ideal. Expect this to be a kite-surfing day, not a paddle-surfing day.

Finally, Saturday morning (5 September) is the standout. The swell drops to 6ft from the west, with a 10-second period, and the energy is still a solid 800. The wind swings to a light south-southwest cross-off, and the waves are clean. This is the best window of the whole forecast. The Peak should be offering some decent, powerful reef waves. Get on it early, because the afternoon sees the wind swing cross-on and the quality drops.

Sunday morning (6 September) is also a good one. The swell is 5ft from the west-northwest, 9-second period, but the wind goes glassy – a light northwesterly breeze that’s nearly nothing. The energy is 333, and the conditions are clean. This is a solid morning session, though the afternoon gets choppy again.

After that, the surf fades. Monday (7 September) and Tuesday (8 September) bring small to moderate swells (3ft to 3ft) with a 12-second period on Tuesday, offering some clean conditions with a light cross-off breeze. The energy is moderate. It’s not a standout, but it’s rideable.

Wednesday (9 September) brings a 5ft west swell with a 10-second period, but the wind is onshore from the northwest, and the energy is 455. The surf is there, but it’s marginal. The rest of the week (10-11 September) is a return to tiny, poor surf with onshore winds. Not worth a paddle.

So, the takeaway: Saturday morning (5 September) is your best bet. Get to The Peak for a clean, 6ft west swell with light cross-off wind. Sunday morning (6 September) is a close second with glassy conditions. The rest of the time, you’ll be waiting.

Rusty.

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.
