The Lowdown

Alright, Rusty here. Let's talk about what's coming up for Fish Boma.

We're looking at a solid run of swell, but it's not all clean. The water is sitting at 60°, which is a bit colder than usual for this time of year, so don't forget a good hood if you're sensitive to it.

The standout window is Thursday the 27th, first thing. We've got a clean 7ft SSW groundswell, with a solid 12-second period, and the wind is absolutely glassy. Zero knots. That's about as good as it gets for a session. The combined energy is strong at 1597, so there's plenty of push. This is an intermediate spot, but with that size and power, it's more for the experienced crew. Crowds are possible, so get there early.

The run-up to that is a bit messy. Tuesday the 25th afternoon has a 8ft SW swell, but the wind is cross and the conditions are only marginal. Wednesday the 26th is a write-off for me – big winds, 15-22 mph, making things choppy despite the 6ft to 8ft swell.

After that Thursday morning glass, things drop off. Thursday afternoon sees it drop to 5ft with a cross wind, and Friday through Saturday are smaller with onshore winds and dropping energy. Sunday the 30th has a bit of a pulse back up to 6ft from the SW, but it's cross-on and the quality is marginal.

We go into a bit of a lull for a few days. Monday the 31st is small and onshore. Tuesday the 1st of September is a big one – a 13ft SW swell with 12 seconds rolls in, but the wind is onshore and the energy is extreme at 8566. That's big, powerful, and messy. Wednesday the 2nd is even worse with 15 mph winds. That's a hard pass for paddle surfing. That kind of setup with that much wind at a reef break is more for the kite crew.

The real second highlight, and it's a proper one, is Thursday the 3rd of September morning. After a few days of chaos, the wind goes glassy again, and there's a clean 8ft SW swell (2391 energy). This is another excellent window for experienced surfers. The afternoon picks up to 10ft from the SSE, but the period drops to 9 seconds, making it a bit lumpy.

After that, the conditions get pretty average. Friday the 4th and Saturday the 5th are onshore and choppy. The swell sticks around, but it's not clean. Sunday the 6th of September morning has a clean 8ft easterly swell with offshore winds, which is a nice surprise, but the period is short at 8 seconds.

The final week sees a slow fade with smaller, inconsistent swells and mostly onshore or cross conditions. There's a small, glassy 5ft window on Wednesday the 9th of September morning, but it's weak.

So, to sum it up: your best bets are the glassy mornings of Thursday the 27th of August and Thursday the 3rd of September. The rest of the time is a gamble with the wind or the size.

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.
