The Lowdown
Alright, let’s switch to feet and Fahrenheit. This is Rusty, and I’m looking at what’s on the cards for Fish Boma over the next couple of weeks.
Right off the bat, we’ve got a solid run of swell coming through. The first real action hits on Friday, August 7th, with a clean 8ft SW swell rolling in, and a cross-off breeze from the ENE making for some excellent, clean conditions. The wave energy is pumping strong at 2762, and honestly, this is one of the best windows on offer. The morning session is the pick for experienced surfers, as it’s a bit beefy for the average punter.
The wind gets a bit messy later on Friday and into Saturday, so those afternoons are less of a focus. Saturday morning has some clouds and a cross-on wind, which chops things up a bit, so it’s worth skipping.
Sunday looks like a write-off with strong onshore winds and rain, pushing the swell up to 10ft to 12ft. That’s expert territory, and the quality is poor, so I’d give it a miss.
Monday, August 10th, is still a bit rough with rain showers and a cross-on wind, but the swell drops to 7ft to 8ft. It’s marginal, not a standout.
Now, here’s where it gets interesting. Tuesday, August 11th, the morning is a ripper. Clear skies, 8ft SSW swell, and a clean cross-off breeze from the ENE. The energy is still strong at 1806. That’s a solid session.
But the real jewel in the crown is Wednesday, August 12th. The morning is glassy. Dead flat calm, no wind, and a 5ft SSW swell with a period of 20 seconds. That’s a very long-period groundswell, and it’s going to be incredibly clean and well-shaped, especially on this reef. The wave energy is still very strong at 2440. This is the best morning on the whole forecast. The afternoon stays clean with a cross-off breeze.
Thursday, August 13th, the morning is another highlight. Offshore wind from the north, 7ft SW swell, and a period of 17 seconds. Clean, powerful, and for experienced surfers. The energy is massive at 2887.
Into the second week, things stay decent but a bit smaller. Friday, August 14th, the morning is clean with a cross-off breeze and 4ft SW swell. The afternoon goes glassy, which is a nice way to end the week. Saturday, August 15th, is another clean day with a cross-off in the morning and glassy conditions in the afternoon, with 5ft to 5ft SW swell. The energy is moderate to strong (1289-1351).
Sunday, August 16th, is a bit of a letdown with light onshore breezes and smaller swell, so it’s marginal.
The following week from Monday, August 17th, looks promising again. The morning is glassy with 6ft SW swell, and the energy is solid at 1348. The afternoon stays glassy, too. That’s a good, clean day.
Tuesday, August 18th, gets a bit onshore, so it’s marginal. The rest of the week through to the 22nd is mostly cross-shore winds and smaller, shorter-period swell, so not a lot of excitement. The exception is Friday, August 21st, in the afternoon: glassy conditions with a 7ft SSW swell, but the period is short at 10 seconds, so it might be a bit crumbly, but it’s clean.
Overall, the standout sessions are the mornings of Wednesday, August 12th, and Thursday, August 13th. That’s where the magic is. The crowds are possible at Fish Boma, so get in early for the glassy ones.

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.
