The Lowdown
Alright, Rusty here. Let’s see what’s cookin’ at Roaches Reef.
First off, don’t get your hopes up for the first week. It’s a slow start with barely a ripple and the conditions are junk. There’s a real dry spell of quality surf here.
Come Tuesday the 11th, there’s nothing—just 0.7ft dribbles from the west with a weak 8-second interval and a cross-onshore breeze. The water is sittin’ at 68° which is over five degrees warmer than normal for this time of year—that’s pretty wild. The combined swell energy is a measly 10. Wednesday the 12th stays tiny, 2ft to 2ft, still cross-onshore. Not worth paddlin’ out.
Thursday morning the 13th shows a little life. We get a bump to 3ft from the WSW at 10 seconds with a light cross-off wind, so it cleans right up. The energy hits 149—that’s moderate. But at this size it’s just a knee-slapper. The guide says it’s surfable but very ordinary. The afternoon gets lumpy with onshore wind.
Friday the 14th and Saturday the 15th drop back under 3ft. The wind is okay but the waves just ain’t there. Sunday the 16th is glassy early with 1ft west swell at only 7 seconds—that’s flat. Monday the 17th is a washout with rain and onshore wind.
Now Tuesday the 18th we get a bump: 4ft from the west at 7 seconds, clean in the morning with a cross-off northwesterly. Energy is a moderate 136. Still short-period and the score is poor, so not a standout.
Here’s where it gets interesting. Wednesday morning the 19th we get a solid 5ft west swell at 7 seconds, and it’s clean with that cross-off wind. Energy jumps to 280. That’s proper short-period swell pumping. Over 5ft is getting into intermediate and above territory. The afternoon gets messy though.
The real standout is Thursday the 20th. Morning is a bit bumpy with a 7ft west swell—that’s expert only territory, over 8ft if you’re strict—but the magic is Thursday afternoon. The swell drops slightly to 6ft from the WNW at 8 seconds, with *glassy* conditions and a light southerly breeze. Energy is pumpin’ at 437. The guide says *expect good surf conditions*. This is your window if you’re experienced. Keep in mind the short period can make it sectiony at the reef, but with glassy water and that size, it’ll be on. Crowds? Roaches can have a crew sometimes—get out there early.
After that, Friday the 21st drops to 3ft and stays small and clean but weak. Saturday the 22nd bumps back to 4ft but the cross-onshore wind ruins it. Sunday the 23rd sees another pulse to 7ft west but the wind is cross-onshore all day—choppy and messy.
The second week fades out into small, windy crap. Nothing from the 24th onwards. By the 26th we’ve got near gale force winds and rain. Total bust.
Bottom line: Thursday 20th afternoon is your best bet. Paddle out if you can handle the size. Rest of the window is either tiny or trashed.
Rusty.

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.
