The Lowdown
Alright, Rusty here. Let’s take a look at what’s on the cards.
Right off the bat, Fish Boma has some energy building but the wind is messing with it for a few days. Starting Saturday the 29th, we’ve got a 3ft S swell at 11 seconds, but that 12 mph WSW cross-on breeze is turning it into a choppy mess. Not worth paddling out.
Sunday the 30th sees a jump to 7ft SW swell, but again, the wind is cross-on and the combined swell energy (988) is moderate, yet it’s still looking marginal. The swell period drops to 9 seconds on the morning, so it’s a bit short and lumpy.
Now, get this – Monday the 31st, early morning. This is the standout so far. We’ve got 5ft SW swell, period stretching out to 12 seconds, combined energy of 719 (moderate), and glassy conditions with a 3 mph S breeze. It’s clean, it’s got good shape, and the energy is solid. Water temp is about average for the time of year. For an intermediate, this is the best on offer in the whole run, no doubt. Get in before the wind swings cross-on later.
Tuesday the 1st of September sees the swell push up to 7ft SW, 12-second period, with a cross-on breeze. Energy climbs to 1133, but the wind keeps it from being perfect. Still, there’s something to work with if you can handle a bit of texture.
Wednesday the 2nd brings 10ft SW swell, 13 seconds – that’s a proper groundswell. Combined energy hits 3377, which is strong. But it’s cross-on or cross-shore all day. This size (over 8ft) is expert territory only, and the wind is the spoiler.
Thursday the 3rd sees the swell drop to 7ft, but breezy and rainy. Not great.
Friday the 4th has 10ft ESE swell at a short 7 seconds – this is more of a windswell, and the fresh 19 mph ESE cross-wind makes it lumpy. This is looking more like a kite session than a paddle surf.
Saturday the 5th of September, morning – clean conditions with 5ft SSW swell, 11-second period, and a 9 mph E cross-off breeze. Combined energy is 1253. It’s clean, it’s fun-sized, and it’s a solid second option for intermediates who missed Monday.
From the 6th through to the 10th, the wind is all over the place, with cross-onshore and choppy conditions, and the swell drops off. A few windows of clean cross-off wind on the 8th and 9th, but the swell is small – below 5ft. Not worth a special trip.
Then Saturday the 12th of September – this is a long-range standout, but keep your expectations in check. We’ve got 10ft SW swell, 15-second period – very long period groundswell. Combined energy is a massive 3811. The wind is cross-off and clean. That size is only for experts, and at a reef setup, it could be epic, but it’s also got that long period which can make it wall up. Sets will be fat and powerful. If you’re experienced and looking for a mission, circle this date.
Sunday the 13th still has 8ft SW swell with clean wind, but it’s the tail end of that pulse.
Overall, the pick of the whole 16-day run is Monday 31st August morning at Fish Boma – clean, glassy, and solid 5ft SW. Everything else is either wind-affected or too big.
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.
