The Lowdown
Alright, grab your wetsuit, let’s break down what’s cookin’ at Fish Boma over the next couple weeks.
Right now, the water’s running at 59°, which is a solid 4° colder than average for this time of year – that’s a bit of a shock to the system if you’re not expecting it. You’ll want a good 4/3, maybe boots unless you’re tough.
The first few days are pretty ordinary. Saturday the 29th is a write-off – cloudy, cross-on wind, weak 3.3ft S swell, energy way down at 572 – just poor, choppy conditions. That afternoon barely improves with a tiny 2.3ft SW swell and light cross-on. Not worth paddlin’ out.
Sunday the 30th morning stays cross-on but the swell bumps to 6.9ft SW, period 9s, energy 1053 – still marginal. Then Sunday afternoon things flip. Glassy winds hit, same 6.9ft SW swell but period lengthens to 12s, energy jumps to 1191. That’s our first real window – clean, well-shaped waves for intermediate surfers. Not huge, but smooth.
Monday the 31st morning stays glassy with 5.2ft SW, 11s, energy 707 – very good conditions. Afternoon gets a light cross-on and drops to 4.9ft, still rideable but less clean.
Tuesday September 1st morning is offshore with 6.9ft SW, 12s, energy 1134 – clean faces, but the afternoon turns cross-on with 7.9ft SW, 13s, energy 1931 – still decent but less perfect.
Wednesday the 2nd has a cross-shore breeze with a solid 9.8ft SW, 13s, energy 3181 – that’s moderate-to-strong energy, big enough to be expert

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.
