The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu at Fish Boma over the next couple of weeks.
We’ve got a slow start, but it’s worth the wait. The first real action kicks off Saturday morning, the 5th of September, with a clean 5-foot SSW swell rolling in. The wind is a cross-off from the east at 12 mph, so the faces will be holding up nicely. The water temp is about average for this time of year, so no surprises there. The swell energy is moderate (698), nothing earth-shattering, but it’s a clean start to the weekend.
Sunday the 6th is where we start to see some serious juice. The morning shows a solid 8-foot SSW groundswell with a very long period of 19 seconds, and the energy is massive (4935). This is proper groundswell, the kind that gets the heart pumping. For a reef setup like Fish Boma, that long period means the waves will have plenty of power and shape, but the sets will be widely spaced. This is strictly for experienced surfers – at 8 feet, beginners should stay well clear. The wind stays light and cross-off, so expect clean, heavy lines. The afternoon pushes up to 10 feet, still clean, but the period drops a touch to 17 seconds. This is the standout of the first week.
Monday the 7th is the real gem. Morning session with 7-foot SSW swell, still a solid 14-second period, and the wind is a light 6 mph cross-off. The combined energy is strong (2926), and the conditions are clean. This is a small window of world-class potential. The afternoon is still good, but the wind swings a touch more cross, so the morning is your session.
The surf settles down from Tuesday through Thursday, with smaller, mixed-up swells. The wind is mostly light, but the direction isn't as clean. You’ll find a few rippable waves, but it’s not the top tier.
Thursday the 10th afternoon brings a resurgence. The wind gets clean again, cross-off from the east, and we get a 6-foot SW swell with a 15-second period. The energy is strong (1907), and the conditions are clean. This is a solid run.
Friday the 11th morning is another good call. Clean 6-foot SW groundswell, light winds, and strong energy (1207). It’s a nice way to finish the working week.
Now, the second week gets a bit wild. Saturday the 12th is a bit of a mixed bag. The morning has a 12-foot SSE swell, but the period is a short 8 seconds, and the wind is a fresh 19 mph cross-off. The setup is more about power than finesse. The afternoon sees the swell hold at 12 feet, but the period is still short at 9 seconds. This is getting into big, lumpy territory.
Sunday the 13th is a beast. The morning has a massive 15-foot east-southeast swell, but the wind is onshore and choppy. The energy is extreme (8850), but the quality is poor. This is a day for the kite guys, not the paddle guys. The afternoon is still big and messy.
From Monday the 14th through to Wednesday the 16th, the swell drops back to a more manageable 6-8 feet, but the wind is mostly onshore or cross-on, so the quality is just average. Tuesday the 15th morning is a brief reprieve – glassy conditions with a 4-foot SW swell, but it’s a small window.
The best bet in the second week is actually Thursday the 17th. The morning shows a clean 8-foot SW swell with a 13-second period, the wind is a solid cross-off from the east at 12 mph, and the energy is strong (2243). The afternoon holds similar conditions. It’s a solid, powerful day for experienced surfers.
The final weekend, Saturday the 19th, looks like another huge, messy swell – 18 feet from the east-southeast, but with onshore winds. Again, that’s kite territory, not a surf session.
So, overall, don't bother paddling out until Saturday the 5th. The absolute standout window is Monday the 7th morning. The second best is Thursday the 17th. Keep an eye on Sunday the 6th if you’re experienced and want big, clean groundswell. The crowds are "sometimes" an issue here, so if you get on that Monday morning, you might have it all to yourself.
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.
