The Lowdown
Alright, Rusty here. Let’s talk about what’s cooking at Fish Boma. This is a reef break, exposed to the south swell, and it likes an optimum swell from due south. It breaks fairly consistently, but when it’s on, it can be a proper wave.
The water temp is sitting right around average for this time of year, nothing weird to report there.
Right now, we’ve got a bit of a slow start. Tuesday the 25th has some solid 8ft SW groundswell rolling in with a long 15-second period, but the wind is on it or cross-shore, and the combined energy is heavy at 3983 (moderate to strong). It’s a bit messy and more for the experienced crew than a beginner session.
Wednesday the 26th is similar story – a 8ft to 8ft SSW groundswell from that long-period energy (16 seconds), but a stiff E wind is making it bumpy. The energy stays up around 2300-3239 (moderate to strong). It’s clean-ish, but not glassy.
Now, Thursday the 27th morning is where it gets interesting. We have a 6ft SSW groundswell at 12 seconds, combined energy of 1610 (moderate), and the wind goes dead calm – glassy. That’s the standout session in the near term. The wave is solid for experienced surfers, and with absolute glass, you’ll be getting clean, lined-up reef waves. The afternoon goes light cross-off, still good but not as perfect.
Friday the 28th morning keeps the theme with a 4ft S swell at 11 seconds and glassy conditions. Energy is at 839 (moderate). It’s a little smaller, but for a morning paddle, it’s going to be very good. The afternoon gets a bit onshore and messy.
From Friday afternoon through to Monday the 31st, the surf gets smaller and the wind turns onshore or cross-onshore. Saturday has a fading 3ft to 3ft swell, the combined energy drops to 550-534 (weak), and it’s just marginal. Sunday the 30th has a weird 7ft spike with a short 7-second period – that’s windswell, not the good stuff. Not worth paddling out for.
There’s a lull of a few days where the quality drops off, but we bounce back on Monday the 1st of September. A 4ft to 4ft SW groundswell with 11-14 second period, cross-off E wind, and combined energy of 522-876 (moderate). Clean, small but fun. It looks like a good morning session.
Wednesday the 2nd of September brings a big pulse of 10ft SW swell at 13-14 seconds, but with strong cross-on or onshore wind. The energy is huge at 3041-4041 (strong). For a reef break, that’s getting heavy and blown out – expert only, and the wind is going to make it a battle.
Thursday the 3rd and Friday the 4th are a write-off with heavy rain, onshore wind, and junky 6ft to 12ft swell. Energy is high but the wind is shredding it. You’d be better off with a towel than a board.
Then, look out for the real standout of the whole run: Saturday the 5th of September morning. A 8ft S groundswell with a 13-second period, combined energy of 2446 (moderate-strong), and light cross-off E wind. That is clean, solid, and a proper step up for the experienced surfer. It’s the best size and quality combo in the whole 16-day window.
Sunday the 6th of September morning keeps the glassy hopes alive with a 4ft SSW groundswell at a very long 16 seconds, light ENE wind, and energy of 1452 (moderate). That long period will wrap nicely into the reef. The afternoon gets a bigger 5ft wave at an even longer 18 seconds, but the cross-shore wind adds a bit of texture.
Monday the 7th morning has a big 10ft SSW groundswell at 15 seconds, strong 3788 energy (strong), with a clean cross-off N wind. That’s big, powerful, and only for experts. The afternoon drops to 7ft but goes offshore at 6 mph – a proper session for the brave.
Tuesday the 8th of September morning finishes the run with a smaller 4ft SW swell at 13 seconds, glassy conditions, and energy at 820 (moderate). A clean, easy end to the period.
Overall, the standouts are Thursday the 27th morning for the glassy perfection, and Saturday the 5th of September morning for the solid, clean size. Fish Boma can get busy, so expect company on those good days.
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.
