The Lowdown

Righto, folks, Rusty here. Let’s have a look at what’s on the table for the next couple of weeks. We’ve got one spot in the crosshairs, and it’s going to be a mixed bag of some serious juice and some real duds, so you’ll need to pick your moments.

The overall pattern is driven by a solid run of southerly groundswells, with some real heavy hitters mixed in and a few days of glassy, clean conditions that will make the most of it. But there are also some windy, messy days and a few dry spells with not much to get excited about. The first real standout is a cracker, but it’s for the experienced crew only.

The action starts on Tuesday, the 1st of September. Fish Boma is the only break in the game, and it’s kicking off with a bang. Tuesday afternoon is looking glassy, with a light breeze from the SW and an 8ft SW swell at 13 seconds. That’s a solid, long-period groundswell and the combined energy is a massive 2414 – that’s strong, powerful stuff. The water temperature is 58°, which is 5° colder than normal for this time of year, so you’ll want a good wetsuit. This is excellent surf, but only for experienced surfers – it’s too big for the beginners. The swell direction is exactly what this reef wants, and with the glassy conditions, it’s going to be clean. This is a true standout, but it’s not for the faint-hearted.

Wednesday the 2nd and Thursday the 3rd of September see the swell hang in there, but the wind gets messy. Wednesday morning is a cross-on breeze with a bigger 10ft SW swell, but the quality is marginal. The wind picks up real strong on Thursday afternoon – a 28 mph cross-on from the SSE with an 12ft S swell at a short 9 seconds. That’s a messy, windy combo that’s a write-off.

Friday the 4th and Saturday the 5th of September are a write-off too, with fresh cross winds making a lumpy mess of the 7ft to 4ft swells. Not worth your time.

Now, Sunday the 6th of September is another big moment. The morning is clean with a 6ft SSW swell, but the real story is Sunday afternoon. We’ve got a 10ft SSW swell with a very long period of 17 seconds, and the combined energy is a huge 7864 – that’s very strong, deep water energy. The wind is a clean cross-off from the E at 19 mph. This is a massive, powerful groundswell, but that long period (over 15 seconds) means it might break a bit straight at a beach break, so it’s best suited to the reef here. The conditions are clean, but this is for experts only. It’s a standout swell, but the caveat is the period.

Monday the 7th of September is a return to glassy in the morning, with a nice 6ft SSW swell at 14 seconds. Clean and smooth, but again, that’s a strong swell for the intermediates.

After that, the surf drops off. Tuesday the 8th through to Saturday the 12th of September sees a lot of smaller, wind-affected, or just marginal waves. There’s a brief window on Thursday the 10th of September morning with a clean 5ft SW swell, but it’s nothing special.

The highlight of the second week is Saturday the 12th of September afternoon. It’s glassy again, with a small 4ft east swell at 10 seconds. The combined energy is only 476, so it’s weak, but with glassy conditions, it’ll be a fun, clean option for the loggers or the longboarders.

Sunday the 13th of September is a messy day of cross-on wind and a poor 6ft SSW swell, so skip it.

Then we get another cracker late in the run. Monday the 14th of September morning is looking excellent for experienced surfers, with a 4ft SW groundswell at 13 seconds and clean offshore winds from the NE. The combined energy is 1055, so it’s got some push. Clean, lined-up waves.

The final highlight is Tuesday the 15th of September morning. It’s glassy, with an 8ft east swell at 8 seconds. That’s a short-period swell, so it’ll be a bit more crumbly and less powerful, but the glassy conditions will make it fun. The combined energy is 1488, so it’s got some beef. This is also only for the experts as it’s over 8ft.

The tail end on Wednesday the 16th of September has a decent 7ft SSW groundswell at 17 seconds, but with a cross wind, it’s a bit average.

So, the two true standouts are the Sunday the 6th of September afternoon (massive, clean, but for experts only) and the Tuesday the 1st of September afternoon (glass, big swell, perfect direction). The week-long mini-gap from the 8th to the 12th is a bit of a dry spell, but it’s not all bad. Keep an eye on those late clean windows.

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.

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.
