The Lowdown
G’day, I’m Rusty. Let’s have a look at what’s on the menu for Fish Boma.
We’ve got a bit of a wait before things get good. A big, messy pulse of swell rolls in on Thursday morning, with a 5ft SW swell pushing through, but the cross-on wind and indifferent tides mean it’s more of a look-and-see scenario. By Thursday afternoon things turn ugly – a 13ft SSE swell with howling cross-on wind is a no-go.
Friday and Saturday are no better. The swell jumps around but messy cross-shore wind keeps everything lumpy. Sunday however, things start shifting. Sunday morning sees a clean 7ft swell from the SSW with cross-off wind. It’s still only marginal, but you can feel the potential. The real spike comes Sunday afternoon with a 8ft SSW swell at a massive 18-second period pushing combined swell energy through the roof (5196). That’s proper groundswell – long lines, plenty of punch, but at a beach break it might run a little straight. Still, this is where it starts to get interesting.
Now, the standout. Monday morning, September 7 – glassy conditions, 6ft SW swell at 14 seconds, combined energy of 2154. The wind is dead calm, the water’s sitting at 60°F, which is about 3°F colder than normal for this time of year, so you’ll feel that chill. But the surf is clean, well-shaped, and set for experienced surfers. This is the pick of the whole forecast. If you’ve got one session to chase, this is it.
Tuesday morning (September 8) keeps things tidy with a glassy 4ft SW swell. Not as big, but still good clean conditions for a more relaxed paddle. After that, the swell drops away mid-week, with small 3ft to 4ft waves and light onshore wind through to Friday. Not worth getting out of bed for.
The next window opens on Sunday, September 13, when a new SSW swell builds to 10ft, but cross-shore wind churns it up. Monday September 14 cleans up nicely with an 12ft SSW groundswell and cross-off wind – combined energy 4195. That’s strong, powerful surf, and at 14-second period it will have real bite. This is for experienced surfers only.
By Tuesday September 15 things ease a little, but glassy conditions return on Tuesday afternoon with a clean 5ft SW swell. A good, safer option if the Monday pulse is too gnarly.
Beyond that, the last week sees moderate 6ft to 8ft SSW swells but onshore wind and lumpy conditions are the norm. Nothing to write home about.
Best on offer: Glassy Monday morning September 7 – 6ft SW, clean, calm, and proper quality. Second standout: Monday September 14 with that big, clean 12ft SSW groundswell for those who can handle it.
Stay safe out there.
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.
