The Lowdown
Alright, Rusty here. Let’s talk about Fall Bay Reef.
It’s a long, rough stretch ahead, mate. For most of the next 16 days, the conditions are junk. The first time you might even think about getting wet isn’t for almost a week.
Tuesday the 15th kicks off with 1.5m west swell, 7-second period, but it’s getting hammered by a 30 km/h cross-off breeze. Water temp is 18°, that’s about 4° warmer than usual for this time of year – pretty noticeable. The combined energy is moderate at 218, but the score is zero – just poor surf.
Wednesday the 16th has a similar setup, but the morning shows a 1.4m, 10-second swell with moderate energy of 384 – still only marginal. It’s not worth your time. Thursday the 17th brings the biggest swell at 1.9m west, but again a short 7-second period, and 30 km/h cross-off winds ruin it.
Sunday the 20th morning is the one real chance. Swell drops to 0.9m from the WSW, but the wind is glassy at 5 km/h from the WNW. Combined energy is weak at 129, but the surf is clean. For an inconsistent reef that can get crowded, this is the window. It’s small, but it’s rideable and smooth.
After that, it fades fast. Monday the 21st is flat and glassy with only 0.6m and 39 energy. Thursday the 24th afternoon shows 1.3m from the west with a solid offshore wind of 25 km/h, but the period is a terrible 5 seconds – it’s just windswell, clean but weak.
Bottom line: Sunday 20th morning is the only real highlight. Crowds are possible. Everything else is blown out or flat. Tough stretch, mate.

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