The Lowdown
Right, grab a coffee. Rusty here, and I’ve been digging through what’s coming for Banna Strand. It’s a classic exposed sandbar on the west coast, and it’s going to be a story of two very different weeks.
The first week is a total bust, plain and simple. There’s a lot of energy in the water, with combined swell energy values from moderate all the way up to a massive 6484 on Thursday the 17th. But the wind is a nightmare—onshore, cross-onshore, and just plain messy from the west and northwest. The wave comment for most of that time is "poor surf conditions". It’ll be lumpy, choppy, and blown to bits. For a few days, from the 15th to the 18th, the swell runs from 8ft up to nearly 15ft, which is strictly for the experts even with good wind, but with that wind, it’s just dangerous and ugly.
The turnaround is sharp. The standout window opens on Monday the 21st of September. The morning brings a clean 5ft swell from the WNW (683 combined energy) with a light cross-off breeze. The afternoon is even sweeter—glassy conditions, a clean 5ft swell from the west, and a "expect very good surf conditions" note. That’s your best bet for a fun, clean session for the average surfer.
The quality holds through Tuesday the 22nd with glassy conditions and a clean 4ft swell. But the big one for the experienced crew lands on Thursday the 24th of September. The morning is clean, with a 7ft WNW swell (1287 combined energy). The afternoon is pure glass with a 7ft swell. The wave comment says "excellent surf conditions for experienced surfers". That’s the date to circle if you’ve got the nerve and the skill.
After that, it fades. The 25th and 26th have some clean but much smaller waves, and then we hit a flat spell at the end of the month. The last few days of September and the start of October are essentially a total blank.
Bottom line: save your energy this week. The 21st is your best bet for clean, fun waves, and the 24th is the one for the charger looking for size and perfection.

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.
