The Lowdown
Alright folks, Rusty here with the lowdown on Banna Strand. The water is running a touch warmer than usual for the season, about 62°F. We’ve got a rocky start wind-wise, but the second half of the outlook is looking much sweeter.
We open on Sunday the 13th morning with a clean 5ft NW swell running at 11 seconds. That’s a solid groundswell with moderate energy, and the cross-off breeze from the south is keeping the surface smooth. It’s a bit inconsistent, but it’s the best we’ve got right now. That’s your one bright spot before a long, ugly stretch.
From Sunday afternoon all the way through to late Thursday the 24th, it’s pretty much blown out or way too big. Monday the 14th is messy with weak, short-period swell and cross winds. Tuesday the 15th brings a 7ft WNW swell under a strong onshore wind – lumpy, wild, and no good for a paddle. That’s kite country with winds hitting 15-19 mph. The middle of the week gets brutal, with 10ft to 13ft WNW swells hitting the beach under fresh onshore winds. Way too big and messy for a sandbar. Wave energy is strong to very strong (over 1000, hitting the 5000s on Thursday afternoon), but it’s all wasted.
Friday the 18th is massive: 13ft at 14 seconds, then 10ft at 13 seconds. It’s just too big for Banna. The wind is cross and cross-on. Only the most experienced should even think about it, and even then, it’s sketchy.
Now for the second week, things get right. Wednesday morning the 23rd has a clean 5ft NW swell with a 9-second period. The wind goes light offshore from the east, giving us clean lines. Energy is mellow. Wednesday afternoon is a gem: glassy conditions with a 4ft WNW swell. That’s a session you’ll remember. It’s inconsistent, but the quality is high.
Thursday morning the 24th offers a 4ft WNW groundswell with a long 14-second period under cross-off winds. It’s clean, but the long period means the sets are slow and the waves might be a bit straight on the sandbar.
The real highlight is Sunday the 27th through Monday the 28th. Sunday morning has a 7ft NW groundswell at 12 seconds. The wind is light offshore from the east-southeast – that’s gentle offshore and clean. This is excellent for experienced surfers. It’s got size, shape, and perfect wind. The energy is solid (1366), just right. Monday the 28th carries that same energy with a 7ft WNW swell under light offshore easterlies. Still very clean and powerful. That Sunday into Monday is your best window across the whole 16-day run.
So, to boil it down: a clean but short session this Sunday morning, then a long, messy gap, followed by a beautiful run of clean, offshore conditions from the 23rd, with the absolute best being Sunday the 27th and Monday the 28th. Mark that on your calendar. That’s the one.
Rusty.

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.
