The Lowdown

Alright, grab your wetsuit, let’s get into it.

We’re looking at a pretty quiet stretch ahead here. The forecast is lean, with surf kicking off small and never really firing, so don’t get your hopes up for anything epic. Water temp is sitting at 66°, which is a solid 6° warmer than what we’d usually see at this time of year – that’s very unusual, feels more like a late summer holdover than early autumn.

Friday morning the 11th is your best bet for a paddle. Roaches Reef has a clean 4 ft swell from the WSW, period at 9 seconds off a light cross-offshore NW breeze at 19 mph. Combined swell energy is moderate at 277. It’s the only real window with anything decent, and even then it’s pretty small. This break is fairly consistent and exposed to the SW swell which lines up with the direction we’re getting.

From Friday afternoon onward, it goes pear-shaped. That breeze swings onshore or messy, and the swell drops, with all the scores tanking. Saturday the 12th stays lumpy and bumpy with an 19-22 mph SW cross-on wind. Sunday the 13th morning is clean but weak – 4 ft with a cross-off – surfable but ordinary.

We get a glimpse of slightly bigger energy midweek. Thursday the 17th morning shows a clean 6 ft from the west, period short at 7 seconds and with moderate breeze, energy climbing to 310. By the afternoon it’s hitting 7 ft and 439, but the quality still gets the thumbs down, so don’t expect anything hollow or organised. That size is at the upper end for intermediates; beginners might want to sit that one out.

From the 19th onward it’s tiny – under 3 ft most days – and the period flops around. By the 23rd we get a long-period 13-second pulse from the WSW, but it’s only 1 ft, so not doing anything. With that long period and tiny height, it’ll be weak and hard to ride at this reef setup. There’s a clean, glassy morning on the 25th of September but with just 0.7 ft on offer, you’re better off taking the camera than the board.

Honestly, there’s nothing in the second week that lights a fire. The whole 16-day window is a mostly flat, weak run, with only the first Friday morning and maybe the Thursday the 17th worth a look if you’re desperate. For most of it, you’re waiting for something that never really arrives. Forecasts can change, but right now this is about as quiet as it gets around here.

Information about the Roaches Reef Surf forecast

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

Roaches Reef is 11 km (7 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.
