The Lowdown
Alright, this is Rusty, and I’ve been staring at the charts for our stretch. Let’s get into it, just you and me.
First off, the water is sitting at 60°, which is a bit colder than normal for this time of year – you’ll feel that difference, so don’t skimp on the rubber.
We’ve got a solid run of SSW groundswell heading our way, starting Sunday morning. The first few days are going to be a bit of a mixed bag with the wind, but we get a real clean-up window on Monday morning that looks choice. That morning session on the 7th of September is a standout: a nice 7ft SSW swell with a long 14-second period, and the wind is a light cross-off from the ENE at just 3 mph. That’s going to leave the surface glassy at Fish Boma (reef). The combined swell energy is sitting at 2794, so there’s plenty of push behind it. This is proper groundswell, so expect long, well-formed lines that will really wrap into the reef. The crowd factor is a "sometimes" here, so you might have to share, but with conditions this clean, it’s worth the company. Just a heads-up: at 7ft, this is more for experienced surfers.
Sunday itself is still surfable, but that east wind is a bit stronger, so Monday morning is the real prize to start the week.
The pattern continues with another pulse of SSW swell. Tuesday morning the 8th of September is a glass-off special. Swell drops a touch to 5ft, but it’s from the east with a short 9-second period and a glassy surface. The energy is moderate (764), so it won't have the same grunt as Monday, but it will be clean, fun, and more manageable.
After a bit of a lull in the middle of the week, the surf really ramps up again. Saturday the 12th of September afternoon is where we see another serious window. The swell jumps back to 7ft from the SSW with a long 16-second period, and the combined energy is a very strong 3596. The wind is a clean cross-off from the east at 9 mph. This is proper, powerful groundswell for the reef.
Later on, Tuesday the 15th of September morning also looks excellent. We get another glassy morning with a 7ft SW swell and a 12-second period. The energy is strong at 1448. Again, the wind is glass, so it will be clean and lined up, but this is another one for the experienced crew.
The last really promising call is on Thursday the 17th of September afternoon. After some messy wind earlier in the day, it cleans up nicely with a 5ft SW swell and light east cross-off wind.
Overall, there’s a lot to like here, but the absolute standouts are Monday morning the 7th and Saturday afternoon the 12th. Those are the days to move your schedule around for.
Stay stoked, and don’t forget the wax.

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.
