The Lowdown
G’day, it’s Rusty. We’ve got a solid run of surf at Fish Boma starting this Saturday, August 15th, and stretching right through the outlook. The swell is coming from the south-west, which is pretty much the optimum direction for this spot, so the setup is right. The water temp is sitting about average for this time of year, so nothing unusual there.
The first few days are a bit of a tease. Saturday the 15th has some swell around 4 ft, but it’s a bit messy with cross-shore winds and the forecast says it’s borderline. Sunday the 16th morning is a write-off with onshore wind, but the afternoon cleans right up – glassy conditions with 4 ft SW swell. That’s a nice gentle start.
Now, Monday the 17th morning is the first real standout. We’ve got 8 ft of SW groundswell with a 13-second period, glassy conditions, and the combined energy is pumping at 609. This is excellent for experienced surfers – the size is up there, and the clean conditions will make it a proper session. Monday afternoon drops off a bit.
Tuesday the 18th morning is another cracker – 6 ft, glassy, excellent conditions. The swell energy is moderate (1119). Then we get a run of great mornings through Thursday the 20th, with 7 ft to 7 ft, glassy, and clean. Thursday afternoon is dead calm with zero wind – that’s a rare treat.
The real highlight of the whole outlook is Tuesday the 25th afternoon. That’s a week and a half away, so it’s a long-range call, but it’s a beauty. 8 ft SSW swell with a very long 17-second period, clean offshore wind, and the combined energy is strong at 3434. The period is extreme – this is proper groundswell, best for a reef setup like Fish Boma, and it’ll hold together beautifully. Crowds are possible here, so get on it early.
There’s a heavy pulse on Saturday the 22nd with 13 ft SSW swell, but the wind is nasty – 35 km/h cross-shore in the morning and a near gale in the afternoon. That’s blown out, and at that size it’s only for experts anyway. Sunday the 23rd is still big but messy.
The last few days of the month settle back into solid 7 ft – 7 ft SW swell with some glassy windows, especially Saturday the 29th morning. Overall, there’s no real gap in the surf – it’s a consistent run, with the best windows being the glassy mornings and that standout Tuesday the 25th afternoon.
Rusty.

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.
