The Lowdown
Alright, folks, Rusty here. Let’s be straight with you—this outlook for Banna Strand is a long haul of frustration with a tiny, fragile light at the end.
The next week and a half is mostly a write-off. We’ve got a big, angry Atlantic pumping in, but the wind is just murdering it. From Tuesday the 15th right through the 19th, it’s onshore, cross-onshore, and lumpy as hell. We’re talking 8ft up to a serious 15ft of WNW swell, but with 30-45 mph winds slapping it flat and ragged. The energy is there—moderate to strong, reading 919 up to a hefty 6689 on the 17th—but it’s all for nothing if you can’t get a clean face. This is not surfable, it’s just a washing machine.
There’s a slight easing on the 20th, but it’s still marginal, with a cross-shore bump. Then on the morning of Monday the 21st, things finally start to look interesting. The wind swings around to a light cross-offshore from the SSE at 10 mph, and the swell drops to a clean 6ft with a 11-second period. That’s a real window of opportunity. The energy is still moderate at 837, but the conditions finally match the swell. This is your first real chance.
Tuesday the 22nd morning is even cleaner—glass with a 5 mph cross-offshore, and 5ft of W swell. But the standout, the one true gem in this whole two-week stretch, is the afternoon of Saturday the 26th. We get a 3ft WNW groundswell with a very long 16-second period, and it’s completely glassy with just a slight air. The energy reading is 981, which is moderate, but that period is special. This is the one to circle. The only caveat—that long period and the sandbar setup here can make things a little straight, but on a glassy day like that, you take it.
The morning of the 27th still has some clean-ish 6ft waves, but the wind picks up hard in the afternoon, and it’s done after that. The final days just fade out into onshore mush and small, messy waves. Not worth getting wet for.
So, the verdict: one solid morning on the 21st, a smoothie on the 22nd, and that magical glassy Saturday afternoon on the 26th is your best bet by far. Everything else? Park the board and watch the horizon.
Keep it salty.

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