The Lowdown
Alright folks, Rusty here. Let's have a look at what Fish Boma has in store for us over the next couple of weeks.
The overall pattern is a solid start, but we’ll see conditions turn a bit messy in the second week. The water temperature is sitting at 60°, which is a bit colder than normal for this time of year, so you might want an extra layer.
The standout session is Monday morning, September 7th. We’re seeing a clean 7ft SSW groundswell with a long 14-second period. The wind is glassy from the ESE at just 3 mph, meaning the surface will be smooth as silk. This is a big, powerful swell with combined wave energy of (2646), so it’s definitely for experienced surfers only. The break is exposed to the south, and the swell direction matches the optimum, so expect some proper, lined-up waves.
Tuesday morning, September 8th, is another good call. The swell drops a touch to 5ft from the east with a short 9-second period, but the wind is glassy again. It’s a bit smaller and more manageable for intermediates, but the energy is moderate (756). Still a clean session before the wind shifts.
Wednesday the 9th into Thursday the 10th sees the swell drop off and wind turns cross-onshore, so not the best quality. Thursday afternoon picks up a solid 8ft SSW swell with a 16-second period and wave energy of (2785), but the onshore wind makes it a bit of a battle. It’s more of a challenge than a clean ride.
Saturday morning, September 12th, offers a glassy window again with a 4ft SW swell (766), good for a relaxed paddle.
Looking further out, Tuesday afternoon, September 15th, is a promising but less certain call. Glassy wind and a clean 5ft SW groundswell with a long 16-second period (1934). That’s a quieter period of the forecast, so keep an eye on it.
Wednesday, September 16th, gets big again with an 12ft SW swell, but the 16 mph cross-onshore wind chops it up. This is too big for beginners, and the wind kills the quality.
From the 17th onward, the wind picks up significantly. There’s still some size, but it’s messy and mostly poor for a paddle. The setup starts to look more interesting for kite surfing than paddle surfing as the breeze strengthens. There’s a gap of several days with no real recommendations here.
Alright, that’s the look from Fish Boma. Stay stoked.
Rusty.

A general guide to surfing at Fish Boma can be found by selecting the local surf guide option on the grey menu.

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.
