The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the cards for Fish Boma over the next couple of weeks.

We've got a solid run of swell on the horizon, but it's going to take a bit of patience to find the real windows. The early part of the forecast is messy, with a lot of cross-shore wind and chop. The wave energy is decent though, with moderate to strong readings for much of the period.

Thursday 10th and Friday 11th are pretty average. The wind is cross-on or cross, and the conditions are chopped up. You'll see some 5ft to 6ft SW swell moving through, but it's not worth paddling out for. The combined energy is moderate to strong (1568 on Thursday morning), but the quality just isn't there.

Saturday 12th gets a bit more interesting, but also windier. By the afternoon, we've got a 6ft SSW swell, but a fresh cross-shore breeze (22 mph) is going to make it a lumpy mess. That energy is strong (2931), but you'd be fighting the wind more than the waves.

Sunday 13th sees a change. The wind swings cross-offshore in the morning and stays that way for a few days. The morning swell is 6ft from the SW (2995 combined energy), and it's clean. But it's the Monday 14th morning that looks like a proper stand-out. We've got 8ft of ESE swell, a light offshore breeze, and the conditions are clean. This is excellent surf for experienced surfers. The only thing is the period is a moderate 10 seconds, so it's not a super-long period groundswell, but the overall package is hard to beat.

Tuesday 15th morning is a beautiful one for the early birds. The wind goes glassy, and there's a 5ft E swell with 11 seconds of period. The energy is moderate (919), but glassy conditions at Fish Boma are a treat. The afternoon gets tricky with a 3ft, 20-second period SSW swell, but the cross-shore wind messes it up.

We hit a rough patch from Wednesday 16th right through Sunday 21st. Onshore winds dominate, and the swell gets big and messy. A 7ft to 10ft SW swell on Wednesday 16th and Monday 21st brings strong energy (3170 and 3068 respectively), but the wind is onshore and the conditions are poor. Not one to get excited about.

Tuesday 22nd and Wednesday 23rd bring some decent swell again (7ft to 10ft) with strong cross-offshore winds, keeping it clean, but it's a bit of a wind-battle at the top end.

The real highlight of this whole outlook, aside from Monday 14th, is the final day, Thursday 24th September. The morning is clean with a 7ft E swell and 11-second period under a light offshore breeze. Combined energy is strong (1556). But the afternoon steals the show: it goes glassy, the swell is a clean 6ft from the east with that same 11-second period, and conditions are perfect. This is the best session on offer. For the afternoon session on the 24th, the light NW wind, glassy conditions, and solid E swell will be magic at this reef.

Remember, if you're looking for a smaller, more manageable day, the Tuesday 15th morning with glassy conditions and a 5ft east swell is a beauty. But for power and perfection, circle the 24th.

What about the water? It's sitting right around average for this time of year, so no surprises there.

So there you have it. Fish Boma will have its moments. The first week is all about waiting for that clean offshore window on the 14th and 15th, and then holding out for that absolute cracker of an afternoon on Thursday the 24th.

Stay stoked,
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.
