The Lowdown
Right, old Fish Boma... we've got a bit of a mixed bag coming our way for the next couple of weeks. The reef here is exposed, so when it works, it really works, but there's going to be a lot of waiting around for the right windows. The water's sitting at 60°, which is a bit colder than normal for this time of year, so you'll want that extra rubber.
Now, some of the early stuff is less than ideal. A bit of a false start, really. We've got a solid 10ft SW groundswell rolling in on the Wednesday morning, period of 13 seconds, but it's coming with a light cross-onshore wind, so it'll be a bit bumpy. That's a massive energy reading off the charts, but the conditions just aren't cooperating. The afternoon cleans up a touch but the cross-shore breeze and 8ft swell won't offer much. Nothing to write home about for the next few days, with strong winds and messy seas making it look pretty ordinary. Friday and Saturday are a write-off with fresh cross-shore winds and lumpy chop on 8ft swells.
Hold on though, we get a real glimmer of hope heading into Sunday the 6th. The morning has a 6ft SSW groundswell kicking in, a period of 19 seconds, and clean cross-off winds from the east. The energy is pumping. This is proper groundswell, long period stuff, and it's going to wrap in nicely over the reef. The afternoon gets even better – swell bumps to 8ft, period drops slightly to 17 seconds, but the energy jumps right up. That's your standout session for the first week. Keep an eye out for a crew though, the crowds are "sometimes" here, and with surf like that, they'll be out.
We then have a bit of a lull through the middle of the week, with smaller swells and onshore winds. Monday the 7th is too messy. By Tuesday the 8th it's small, weak and offshore but the energy is barely there, so not really worth the paddle. Then there's a real gap in quality until we look into the second week.
Looking further out, we've got some potential but it's a long-range call. On Monday the 14th of September, there's an 8ft ESE swell, period of 10 seconds, hitting with light cross-off winds. It's clean, the energy is moderate, and it's flagged as excellent for experienced surfers. That's your second standout – a bit more friendly, but still punchy.
The last big hoorah looks like Thursday the 17th of September. We're talking a 12ft SW swell with a period of 14 seconds and light offshore winds. The energy is massive. That is a serious swell, only for the experienced crew, and it'll be a big, powerful reef break. The afternoon sees a drop to 10ft but it's still cranking. That’s one to circle on the calendar, but treat it as promising rather than a done deal.

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.
