The Lowdown
Alright folks, it's Rusty here. Let's be straight with you – this is one of those outlooks where patience is the name of the game. We’re looking at a long dry spell before anything worthwhile shows up.
For Bantham, the first ten days are basically a write-off. From Sunday the 16th right through to Wednesday the 27th of August, we’ve got next to nothing. Tiny dribbles of swell, mostly under 3 feet, and the wind is just horrible – cross-on, onshore, and fresh. You’ll be staring at choppy, lumpy, poor surf conditions. There is a brief moment on Friday the 21st afternoon where it goes glassy, but with only 1 foot of swell, it’s barely a ripple. The combined wave energy is feeble, reading 28 (weak energy). You’d be better off checking the kite setup if you’re desperate.
Then, on Friday the 28th of August, things finally get interesting. We see a real pulse of energy arrive. The morning brings a 4-foot swell from the WSW with a 10-second period, and by the afternoon it jumps to 6 feet from the W with a 9-second period. The combined energy hits a solid 314 in the morning and 745 in the afternoon (moderate to strong wave energy). This is the standout of the entire 16-day window. It’s a bit too big for beginners, but for everyone else, it’s game on. The only catch? The wind is onshore from the SW, so it’s going to be a bit bumpy. But when you’ve been waiting that long, a little chop is a small price to pay for some actual waves.
Given the length of the flat spell, I’d be marking that Friday the 28th in your calendar now. It’s not perfect, but it’s the only proper surf we’re going to see.
Rusty.

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