The Lowdown

Right, mate, Rusty here. Let’s have a proper look at what Fish Boma has cooking over the next couple of weeks. It’s a reef set-up that loves a good south swell, and we’ve got some significant energy coming through. The water temp feels about average for the time of year, nothing weird going on there.

The week kicks off with a bit of a mess, honestly. Sunday morning the 13th has some solid, very long period south-west groundswell – we’re talking 15-second intervals – with a combined energy pushing 3130, which is strong. But that east wind is blowing cross-offshore, making things tricky. It’s clean, but the conditions are marginal and the score is just fair. That afternoon the wind swings cross-shore, not helping much. Monday the 14th and Tuesday morning the 15th are pretty poor, with onshore winds and messy conditions. Tuesday morning the 15th does go flat calm though, with glassy 1.6m easterly swell, but it’s short period stuff at 11 seconds.

The real first stand-out window opens on Monday the 21st. Monday morning we get a glassy-offshore calm, with a 1.5m south-west swell riding long 12-second periods. The combined energy is moderate at 1258, but the conditions are excellent for experienced surfers. The water is clean, and that’s a good session.

Tuesday the 22nd morning is also a gem. Solid 1.8m south-west swell with a very long period of 16 seconds – that's groundswell with real grunt. The wind is cross-offshore from the east, keeping the faces clean, and the combined energy is strong at 2426. A reef like this loves that long-period south-west. Crowds are sometimes a factor here, so you might have to share, but it’s worth it.

Then Wednesday the 23rd morning, another glassy-offshore set-up. Dead calm, 1.7m south-west swell with a 13-second period. Clean as a whistle. The energy is moderate at 1545, but the quality is there.

Later in the fortnight, Thursday the 24th morning sees a 2.1m south swell with a shorter 10-second period, but it’s glassy again. Good for the more experienced crew. However, by Saturday the 26th we’re looking at a 3.0m easterly swell, but with an 8-second period – that’s short period and lumpy. Sunday the 27th morning pushes a 2.2m south-west swell with an incredible 18-second period and combined energy of 4330. That’s very strong. But the wind is cross-on, making it choppy, and the overall conditions are poor. It’s a lot of power but messy – one for the experts and maybe even kite-surfers given the wind and size.

So, the absolute pick of the bunch is Tuesday the 22nd morning for that long-period south-west groundswell with clean cross-offshore winds. Monday the 21st morning is a close second for the glassy conditions. The second week has some promising pulses, but they come with wind issues, so stay tuned.

Rusty, signing off.

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.
