The Lowdown

Alright, Rusty here, and we’ve got a look at a single spot for the next couple of weeks. The only game in town is Fish Boma, a south-facing reef break that’s got a pretty good reputation. Right now, the water’s sitting at 59°, which is a solid 4° colder than usual for this time of year – that’s a noticeable chill, so you’ll want the thicker wetsuit.

The good news is there’s a long run of swell coming from the south-west, and the first few days are mostly clean with light winds. But the catch is that for today, Sunday the 30th, and into Monday the 31st, the surf is described as marginal. The swell is there – about 7 ft to 7 ft today (from the SW) – but the timing or conditions aren't clicking for anything special. You might get a few, but it’s not the standout.

The first real sign of something promising builds through Tuesday, September 1st. Morning sees a 7 ft SW swell with a nice 12-second period, and it’s got a clean offshore wind from the SSW. The combined energy is solid (1401). That's a nice window before the afternoon sizes up to 8 ft with an even longer 13-second period (2187 energy). That’s a proper groundswell pushing in, and with those light offshore winds, it’s going to be clean. Keep in mind, at 8 ft this is starting to push into expert territory, but for the experienced crew, Tuesday afternoon is the first true standout.

Wednesday the 2nd sees the swell peak. The morning is 10 ft from the SW with a long 14-second period (3072). That’s a powerful, heavy swell. The wind is cross-shore, light, so the takeoff might be a bit tricky but it’s still workable. This is big and strong – expert only. Afternoon gets a bumpier cross-offshore breeze that spoils it a little.

Then the wind turns ugly. From Thursday the 3rd through Friday the 4th, we get moderate to fresh cross-shore winds and some rain. Swell drops and gets messy – wave energy is lumpy, and the period shortens up. Not worth paddling out. Saturday the 5th is better, but still cross-shore with moderate breeze. The quality is just average.

Now, here's the real highlight of the whole outlook: Sunday, September 6th. This is the day. The morning brings a 7 ft SSW groundswell with a 13-second period, but the magic is the wind – glassy. Absolutely flat calm. That’s “excellent surf conditions for experienced surfers” right there, and the combined energy is pumping at 1684. This will be the cleanest, most lined-up session of the two weeks. Afternoon stays good with a clean cross-offshore breeze. If you can pick one day, this is it.

After that, the swell fades fast. The second week is much quieter. From Monday the 7th through to around Thursday the 11th, we’re looking at weak swell (under 4 ft), mostly poor winds, and generally poor surf conditions. There’s almost nothing to get out of bed for. The energy values drop to the low hundreds – real weak stuff.

Things perk up a little again on Saturday, September 12th. We get a 8 ft SW swell with a 13-second period and a clean cross-offshore wind (energy around 1900). It’s punchy, but it’s not as clean as the 6th and the wind is stronger.

Finally, Sunday, September 13th has another glassy morning with a 6 ft SW groundswell, but the energy is moderate (929). It’s a nice, smaller follow-up session.

And then the window closes with Monday, September 14th, which shows a massive 10 ft SW swell with a 15-second period and offshore wind – energy over 4000 – but it’s listed as marginal. That’s big, long-period energy that needs a reef like this, but at that size it’s a serious, serious challenge. Only for the heaviest local chargers.

Because this is a reef break that can handle the longer-period groundswell, it’s the right spot for this. It will hold the line better than a beach break would.

Signing off – 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.
