The Lowdown

Righto, let’s have a look at what’s on the cards for The Peak. This spot is a reef break, exposed to the west, so it hoovers up any westerly swell that rolls through. It’s fairly consistent by nature, but the next week or so is looking pretty grim – a lot of onshore junk and messy conditions. We’ve got a fair gap of poor surf ahead before things turn around.

Starting off Monday the 7th, it’s a write-off. We’ve got rain showers and a strong cross-shore wind at 16 mph, swinging up to 22 mph in the afternoon. There’s some swell – about 5 ft to 7 ft from the west – but the wind is just ruining it. The water is sitting at a balmy 62°F, which is much warmer than normal for this time of year, about 4°F above average, so that’s a bit unusual. Nothing to get excited about in the water though.

Tuesday the 8th isn’t much better. Swell jumps to 8 ft out of the west-northwest, with a period around 10 seconds, and the combined energy is pumping hard (1451), but it’s all under onshore wind at 22 mph. That’s expert-only territory if you’re desperate, but honestly, it’s messy. The rest of the week into the weekend stays poor – Wednesday through Friday there’s dribbly 3 ft to 5 ft swell with cross and cross-on winds. Not worth paddling out.

Saturday the 12th is where we finally see a flicker. There’s a solid 7 ft swell from the west-northwest, period jumping to a very long 14 seconds – that’s proper groundswell energy (1419). The wind is cross-offshore at 16 mph, and the conditions turn clean. This is a marginal call though, because at a reef break like The Peak, a long-period swell from that direction can sometimes be a bit straight, but the clean wind helps. It’s a Saturday, so crowds are sometimes a factor here, but this is the first real seed of hope.

Sunday the 13th and Monday the 14th drop back down into poor territory. Monday afternoon actually gets messy again with cross-on chop. Then Tuesday the 15th sees another big pulse – 8 ft at 11 seconds from the west-northwest, energy reading 1505 – but the wind is cross and cross-on again, making it lumpy. That’s not clean surf.

Now, here’s the real standout. Thursday the 17th of September. The swell holds at 8 ft from the west, period 11 seconds, energy 1348, and we get clean, moderate offshore wind from the southeast. The surf report calls it excellent for experienced surfers – this is legit. It’s not for beginners at this size, but for a confident crew, this is the session to circle. The offshore wind is a major positive, keeping the reef lines clean.

Friday the 18th of September is even bigger. Swell hits 8 ft from the west, period 12 seconds, and the energy is massive at 2310. Offshore wind from the southeast at 16 mph keeps it clean. Again, this is expert territory – don’t take a foamboard out here. If you’re comfortable in heavy reef waves, this is the best on offer across the whole outlook.

Saturday the 19th and Sunday the 20th still have plenty of size (6 ft to 8 ft) with clean winds, though Saturday afternoon gets a bit rated down due to tide or something, but still clean. After that, the last few days into Monday the 22nd fade out to small 4 ft to 5 ft leftovers with light wind.

So, the big picture: a long stretch of rubbish until the middle of next week. Then Saturday the 12th offers a glimpse, but the true standouts are Thursday the 17th and Friday the 18th – both offering solid, clean, offshore west swell. Get your boards ready for that window.

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.
