The Lowdown

Alright, let’s get into it. This is Rusty, and I’m looking at the run for Fish Boma. This is a reef break, and it’s the only spot we’ve got in the books for the next couple of weeks. Let’s break it down.

First up, the water’s running about average for the time of year, so nothing funky there. The first bit of action worth paddling out for is Friday morning the 28th of August. It’s a bit cloudy with a light cross-onshore breeze, and we’ve got 4.3ft swell out of the south, with a 11-second period. The energy’s moderate (774), so it’s fair to say it’s a bit of a warm-up. Not the cleanest, but it’s better than nothing.

Friday afternoon is where it starts to clean up. The wind goes glassy, with a 3.9ft south swell still at 11 seconds. The energy drops a bit (688), but the glassy conditions make it rideable. A solid little session for the intermediate crew.

Saturday and Sunday are a bit of a mixed bag. Saturday morning has a 3.3ft south swell but the wind is cross-onshore and choppy – not great. Sunday morning gets a bit of light rain, but the swell is 4.3ft out of the southwest at 13 seconds, with light cross-onshore wind again. The energy is moderate (955), but still marginal.

Now, here’s the standout. Sunday afternoon the 30th of August. The wind goes glassy, and we’ve got a 6.6ft southwest swell, 12-second period, and the energy jumps to strong (1190). This is excellent surf for experienced surfers. The swell’s getting a bit sizey, but the glassy conditions will make for some clean, lined-up waves. This is the best on offer in the first week.

Monday the 31st is a write-off – choppy, cross-onshore wind, poor conditions. Not worth your time.

Tuesday the 1st of September morning is another gem. Glassy calm, 7.2ft southwest swell at 12 seconds, and strong energy (1313). This is excellent for experienced surfers again. The wind is dead calm, so it’ll be clean. The afternoon turns onshore and drops off a bit.

Then things get wild. Wednesday the 2nd of September morning brings a massive 14.8ft swell out of the SSW with a 19-second period – that’s very long period groundswell. The energy is through the roof (12443). But the wind is a fresh cross-onshore, and it’s lumpy. This is expert-only territory, and honestly, it’s looking more like a kite surfing setup than a safe paddle out. The afternoon has the same size but the wind is onshore, so still tricky.

Thursday the 3rd is messy. Strong cross-shore winds, lumpy chop, and a 13.1ft swell with a short 8-second period on the afternoon. Not good.

Friday the 4th of September is huge. 26.2ft to 29.5ft swells out of the ESE with very long periods (12-13 seconds). The energy is insane (18559 to 26960). The wind is offshore, so the waves will be clean, but it’s just too big for this break. I’d say it’s definitely a kite surfer’s dream, but for paddle surfing, it’s a no-go unless you’re a total nutter.

Saturday the 5th of September morning is a return to form. 13.1ft ESE swell, 12-second period, with light offshore wind. The energy is strong (4921), and it’s clean. This is excellent for experts. The afternoon goes glassy with 11.5ft ESE swell – still excellent, but still big.

Sunday the 6th of September morning is glassy with 7.5ft ESE swell at 12 seconds, strong energy (1925). Excellent for experienced surfers. The afternoon gets a bit of cross-onshore wind, but it’s still a decent 5.9ft.

After that, the surf drops off. Monday the 7th and Tuesday the 8th are small and choppy, not worth it. Wednesday the 9th of September afternoon has a 7.2ft SW swell at 12 seconds with clean offshore wind – that’s a good one for experienced surfers again.

The last few days of the run get big again. Thursday the 10th and Friday the 11th of September see 9.8ft to 14.8ft ESE swells, but the wind is cross-onshore and the period is short (8 seconds) on Thursday, so it’s lumpy. Friday has 14.8ft ESE swell at 11 seconds, but still cross-onshore. Saturday the 12th of September morning has 7.9ft ESE swell but onshore wind and rain – not great.

So, the true standouts in this 16-day window? Sunday afternoon the 30th of August and Tuesday morning the 1st of September. Both have glassy conditions, solid 6.6ft+ SW swell, and strong energy. For the second week, Saturday the 5th of September morning and Sunday the 6th of September morning are the best bets, with clean offshore winds and

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.
