The Lowdown

Alright, Rusty here. Let’s take a look at what Three Peaks has cooking over the next couple of weeks.

First thing to note: the water’s sitting at a warm 65°, which is about 5° warmer than usual for this time of year – that’s a big deal, you’ll barely need a spring suit.

Honestly, the first week is mostly a bust for quality waves. From the 13th through the 19th, we’ve got swell but the wind is just brutal – mostly onshore or cross-onshore from the WSW and NW, and the conditions are consistently rated as poor. The swell energy is weak to moderate, like on the 13th it’s 358 (moderate), but it’s all blown out and messy.

The one bright spot in that first week is the 20th of September. Sunday morning has a light cross-off breeze from the NNE, and by the afternoon the wind turns to a light offshore from the ENE at just 6 mph. That’s clean. The swell is small though, only about 3ft from the WSW at 8 seconds, with a combined energy of 133 (weak). It’s surfable but nothing to write home about. Still, it’s the best we’ve got for a while.

Then there’s a gap from the 21st through the morning of the 22nd with nothing worthwhile.

Next chance is the 22nd of September, Tuesday morning. The wind is a clean cross-off from the north at 16 mph, and we’ve got a 6ft W swell, period a short 7 seconds, combined energy 255 (moderate). The conditions are clean, but the short period means it won’t have much shape. Still, it’s clean.

The standout of the whole outlook is the 23rd of September, Wednesday. Morning has a clean cross-off north breeze, and the swell pushes up to 7ft from the west, still a short 7 seconds. The combined energy jumps to 382 (moderate) in the morning and then a strong 642 (strong) in the afternoon. That’s serious power. The wave comment says “marginal” because of the short period and beach break setup, but if you’re an experienced surfer, that afternoon session has some real punch. Beginners should stay out of the way – 7ft is too big for them, and the short period makes it dumpy.

After the 23rd, the swell drops off fast. From the 24th through the 28th, we’re looking at tiny waves, mostly under 2ft, with very low combined energy (down to single digits and twenties). The winds are clean but there’s just no swell to work with.

So to wrap it up: the 20th is your small, clean, easy day for a paddle. The real standout is Wednesday the 23rd, especially the afternoon, with strong energy and clean winds – just know it’s short-period and punchy, so only for those who can handle it.

Rusty.

Information about the Three Peaks Surf forecast

The above surf forecast table for Three Peaks provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Three Peaks can be found by selecting the local surf guide option on the grey menu. Our Three Peaks 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 (Three Peaks) 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 Three Peaks 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.

Three Peaks is 25 km (16 miles) from Swansea. If you plan a holiday in Wales - Gower, look for hotels and other accommodation in Swansea. Swansea has rooms for a wide range of budgets as well as car hire and transport links.
