The Lowdown

G’day, Rusty here, and I’ve got the scoop on what’s comin’ our way. We’re lookin’ at a solid run of swell, but you’ve gotta pick your moments. The water’s sittin’ at about 63°, which is pretty much bang on average for this time of year, so nothin’ wild there.

The real story starts Tuesday the 4th of August. It’s a bit of a slow burner with some chest-high swell around 4ft from the SW. The combined energy is moderate at 789, and the wind’s light and cross, so it’s okay but nothin’ to write home about. By Tuesday afternoon though, it cleans right up with glassy conditions and the same 4ft SW swell – that’s a nice little session if you’re keen.

Wednesday the 5th sees the swell start to build. Morning’s got 4ft from the SSW with a period of 15 seconds, that’s a proper groundswell, and the energy jumps to 1137. Wind’s light cross-on, so it’s a bit bumpy. Wednesday afternoon gets bigger – 7ft from the SW with a 16-second period, energy at 2114, but still that cross-on breeze. It’s gettin’ there.

Thursday the 6th is pumpin’ but messy. We’re talkin’ 10ft in the morning from the SW, 13-second period, and energy at 3445. That’s a lot of water, but the wind’s cross-on again, so it’s a bit of a washing machine. Afternoon drops to 8ft, still cross-on. This is expert territory if you’re brave enough to deal with the chop.

Now, Friday the 7th of August is a standout. The morning’s got 8ft from the SW, 14-second period, and the wind is dead calm – glassy as. Energy at 2604. That’s clean, powerful surf for experienced surfers. Friday afternoon is even better: 8ft, 15-second period, glassy, and energy at 3222. This is the best of the early run, no doubt.

Saturday the 8th is a step back. The swell’s still 8ft from the SW, but the wind picks up to 9 mph cross-on, makin’ it choppy. Energy drops to 2595. Still surfable, but not as good.

Sunday the 9th is a write-off. Light rain, 12ft to 15ft of SW swell, and onshore wind hittin’ 19 mph. Energy is through the roof at 3893 to 5363, but it’s a mess. That’s more for kite surfers than paddle surfers.

Monday the 10th of August is another gem. The swell’s 13ft from the S with a 11-second period, but the wind is glassy. Energy is 3817. That’s a big, clean swell for experts only. If you’re good enough, it’s a dream. Afternoon drops to 10ft from the SSE, still clean but with a light cross breeze.

The rest of the week stays solid. Tuesday the 11th has 8ft from the SSE with clean cross-off winds, and Wednesday the 12th is a ripper. Morning sees 8ft from the ESE, 13-second period, and offshore winds from the NNE. Energy is 6210 – that’s strong. This is exceptional surf for experts. Thursday the 13th of August is the absolute standout. Thursday afternoon has 10ft from the ESE, 14-second period, light cross-off wind, and energy at 9240. That’s huge, clean energy. If you’re an expert, that’s your session.

The swell eases from Friday the 14th, with 7ft from the ESE, and then we drop off. The 15th and 16th are small, 4ft to 5ft from the SW, with light cross-onshore winds. Not much goin’ on. Then Monday the 17th of August, the swell picks up again to 10ft from the SW, but it’s cross-on and choppy. By Wednesday the 19th, we get one last glassy pulse: 7ft to 8ft from the SW, 12-second period, and glassy conditions. That’s a clean finish.

So, the two standouts are Friday the 7th of August, with glassy 8ft SW groundswell, and Thursday the 13th of August afternoon, with 10ft ESE groundswell, light wind, and massive energy. Crowds are possible at Fish Boma, but with that quality, it’s worth it. Keep your eyes on the dates, and don’t sleep on those Thursday afternoon waves.

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.
