The Lowdown
Alright, Rusty here, let’s break down what’s on the table.
Right off the bat, this is a pretty quiet stretch for Fall Bay Reef – a tricky, inconsistent reef setup that needs the stars to align. The water is sitting at 66° right now, which is a whopping 5° warmer than normal for this time of year – that’s very unusual, almost feels like the middle of summer out there. But the surf is not matching the warm water. We’ve got a blank run for the first few days: nothing but poor conditions from Wednesday 9th right through to Thursday 10th with lumpy, messy wind and tiny swell. A bit of a wait.
First real glimmer comes Friday morning 11th. The swell picks up to 5ft out of the WSW with a 9-second period and the wind goes light offshore from the NW. That’s clean, that’s workable. Not a monster, but for this spot, it’s the best we’ve seen. The combined energy is moderate at 307 – enough to push you around. It’s a standout simply because everything else is poor or blown out.
Then we get another chance on Sunday 13th in the morning. Smaller again at 4ft from the WSW, but that 10-second period is nice and clean with a light offshore from the N. The energy is solid (245) for the size. It won’t be cranking, but it’ll be tidy. A decent runner-up.
The next real highlight is Wednesday 16th in the morning. Swell is 4ft straight out of the West, with a clean moderate offshore from the NNE (16 mph). The combined energy jumps to moderate-strong at 305. That will give you some nice, lined-up walls. Again, the wind is the key here – clean and offshore. This is another good call for the intermediate crowd.
Looking deeper into the second week, Sunday 20th morning looks promising but it’s a long way out. Swell is up to 7ft from the West, and if the forecast holds, the wind is light WNW cross-offshore which would be glassy. Energy is high at 609. That’s a proper swell size – just on the edge of being too big for beginners, but good for the experienced crew. The caveat here is that it’s over a week away, so don’t lock it in yet.
Outside of those windows – Friday 11th, Sunday 13th, Wednesday 16th, and maybe Sunday 20th – it’s mostly onshore junk, cross-chop, or flat spells. The consistency at Fall Bay Reef is poor to begin with, so this kind of patchy run isn’t surprising. When it’s good, it’s fun; when it’s not, there’s really nothing to chase.
Keep your eyes on the Friday morning and that mid-week Wednesday session for the cleanest, most ridable waves.
Rusty.

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.
