The Lowdown
Alright folks, Rusty here. Let's get into it. We've got one break on the cards for this stretch, and it's a bit of a mixed bag.
We're looking at a solid run of pulses down at Fish Boma (reef). The water is sitting at 60°F right now, which is a bit colder than normal for this time of year, so don't forget a good hood if you're heading out.
The first decent window opens up on Friday afternoon, August 28th. The morning is a bit of a write-off with iffy conditions, but by the afternoon, the wind goes glassy, and you've got a clean 4ft S swell at 11 seconds. It's not the biggest, but it'll be your best chance for a fun, uncrowded session to kick things off. The combined energy is moderate (765).
Saturday the 29th is a bit of a letdown. The morning is choppy with cross-on wind, and the swell drops to 3ft. The afternoon cleans up with a cross-off breeze, but it's only 2ft of SW groundswell with a 13-second period. It'll be tidy, but you'll be scratching for waves.
Sunday the 30th is where the energy starts to build. The morning is messy with a 6ft SW swell (9 seconds) and cross-on wind, but hold out for the afternoon. The wind drops to glassy, and the swell jumps to 7ft from the SW with a 12-second period. The combined energy is strong (1209), and conditions are excellent for experienced surfers. This is a standout session for the first week.
Monday and Tuesday are a bit of a washout with cross-on wind and marginal conditions, despite the swell holding around 5ft to 8ft.
Now, here's the big one. On Wednesday, September 2nd, we get a monster. The morning session sees a massive 13ft groundswell from the SSW with a super long 17-second period. The wind is offshore from the E, and the combined energy is absolutely pumping (8282). This is exceptional surf, but only for experts. The afternoon is still huge (12ft, 16 seconds), though the wind picks up to 16 mph, making it a bit more challenging.
After that, the swell starts to drop but remains hefty. The 5th of September offers a few days of solid 10ft to 12ft ESE swell with offshore winds, which is excellent for experienced surfers.
There's a gap of a few days with smaller, weaker surf from the 6th to the 10th of September, before another pulse arrives on the 12th. The morning of the 12th is a bit of a question mark, but the afternoon of Saturday, September 12th, is a standout: glassy conditions with a 13ft S swell. The combined energy is huge (2968). It's a solid, clean pulse for those who can handle it.
The absolute best on offer is the Wednesday morning (September 2nd) session at Fish Boma. That's a serious, serious swell with perfect offshore wind. Second best would be the glassy afternoon on Sunday, August 30th, or the glassy afternoon on September 12th.
The only thing to keep in mind is the long period swells (15 seconds and up) can make beach breaks a bit too straight, but for a reef break like Fish Boma, they'll be lined up and juicy.
Rusty.

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