The Lowdown
Alright, this is Rusty. Let's get straight into it.
Alright folks, the next couple of weeks are a bit of a mixed bag here. We're looking at a real slow start, but there's some serious firepower waiting on the horizon if you can be patient. The60° water is running a bit colder than normal for this time of year, so you might want an extra rashie.
We kick things off on Thursday the 27th with some small, average energy. After that, the beginning of September is where the real story starts. There's a big gap of nothing special from the 28th to the 31st of August and into the 1st of September, so don't rush for the first few days.
The standout window opens on Tuesday the 1st of September. Afternoon at Fish Boma is going to be the pick. We've got a solid 8 ft swell from the SW, and the wind is dead calm—glassy as a lake (133 m). This is clean, powerful surf for experienced crew. It’s going to be pretty big for beginners though, so if you're not solid, give this one a miss.
The week after that gets serious, but you need to be cautious. On Wednesday the 2nd of September the swell jumps to a massive 20 ft from the SW with a very long period of 17 seconds. The combined energy is a mind-boggling 42002. This is expert territory only, and the cross-onshore wind is making it lumpy and mean. Honestly, this setup looks more interesting for kite surfing than paddle surfing.
If you can suit up on Thursday the 3rd of September, the morning session is the real gem. Glassy conditions again, with a 12 ft SW groundswell (4943 m). The long period of 14 seconds is going to grind down that reef perfectly. This is another one strictly for the hardcore, but the quality is undeniable.
Then we roll into the second week. Sunday the 7th of September morning offers a very clean 7 ft S swell with calm winds (133 m). Excellent conditions for the experienced surfer again.
Later on, Friday the 11th of September is worth a look, with clean, cross-offshore winds and a 6 ft to 7 ft SW swell. The energy is moderate, and it’ll be a cleaner session than the size suggests.
The break is fairly consistent but the quality varies wildly. Keep your eyes on the 1st and 3rd of September for the true standouts. Crowds are possible at Fish Boma when it's on, but that big swell on the 2nd will keep the numbers down.
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.
