The Lowdown
Alright, Rusty here, let’s get into it.
We’ve got a solid run of surf coming up at Fish Boma, a reef setup that’s exposed to the swell. The water is sitting at 63°, which is bang on average for this time of year, so nothing weird going on there.
Things kick off on Monday, August 3rd, with a clean 6ft ESE swell, period around 11 seconds, and glassy conditions in the morning. The combined energy is pumping at 1255, so there’s some proper push behind it. This is excellent for experienced surfers. The wind stays light and cross-off in the afternoon, keeping it tidy.
Tuesday the 4th drops a bit in size to 4ft from the SW, but with a 12-second period, the shape should be nice. Morning has a cross-off breeze, so it’s still clean. By afternoon, a cross-shore wind creeps in, making it a bit lumpy, but still surfable.
Wednesday the 5th sees the swell building again, 5ft in the morning from the SSW with a very long 16-second period, but the wind is cross-onshore, putting some ripples on the face. The energy jumps to 1369. By afternoon, it’s a full 7ft onshore wind, but the swell period is still 16 seconds – it’s a lot of water moving, but the wind is messy.
The standout window is shaping up to be Thursday the 6th through Sunday the 9th. Thursday morning has a solid 10ft SW groundswell, 13-second period, and strong energy at 3472, but it’s cross-onshore and choppy. That’s big, powerful, and rough – kite surfers would be having a field day here, but for paddle surfing, it’s a battle.
Now, Friday August 7th is the real gem. Morning session is glassy, 8ft SW groundswell with a 15-second period, and the energy is a massive 2826. The wind is dead calm. This is excellent for experienced surfers, and the question is: can you handle a reef break with a 8ft groundswell? It’s going to be powerful, long walls, and with that period, it’ll be lining up. Afternoon stays clean with a cross-shore breeze and 14-second period. This is the best on offer.
Saturday the 8th drops a touch to 8ft, but the wind is cross-onshore and picking up, making it choppy. Not the same quality.
Sunday the 9th is a write-off. Heavy rain, strong onshore wind at 16 mph, and 10ft messy swell. The energy is still high at 2692, but it’s a washing machine. That’s a day to stay on the beach.
There’s a gap of poor conditions until Monday the 10th, which is a smaller 7ft SSE swell, cross-shore wind, and only moderate energy. Not great.
Tuesday August 11th is another good call. Morning has a clean 6ft SSW groundswell, 13-second period, and light offshore wind from the NE. The energy is 1172. It’s clean, well-shaped, and much more manageable. Afternoon gets a cross-shore breeze, but the morning window is pure.
Wednesday the 12th is a weird one – a tiny 2ft SSW swell but with a 22-second period! That’s a very long period groundswell, and the energy is still 1028, so it won’t be flat. Glassy in the afternoon. For a reef, that long period could make it really fun and lined up, even if it’s small.
The next big window is Thursday August 13th through to Saturday August 15th. This is the big one. Thursday morning starts with 7ft SSW, 18-second period, and energy at 3954 – that’s a lot of juice. The wind is light cross-onshore, so not perfect, but it’s building. By Friday August 14th, it’s 10ft SW, 15-second period, glassy in the morning, and the energy is 3640. This is excellent for experts. Saturday the 15th holds similar size, 10ft SW, 15-second period, with 4337 energy – the biggest energy reading of the whole run. The wind is onshore, so it’s going to be a bit lumpy, but the power is undeniable.
Sunday August 16th cleans up again, with a 6ft SW groundswell, 12-second period, and glassy conditions in the morning. A solid, fun day.
The rest of the run into Monday the 17th and Tuesday the 18th sees dropping size, and onshore winds creep back in, so it’s back to average conditions.
The standout: Friday August 7th morning – glassy, 8ft SW groundswell, 15-second period, massive energy. That’s the session to circle. The second standout is Friday August 14th morning – same story, bigger size (10ft), glassy, and even more energy. That’s a proper expert-only day.
Crowds are possible at Fish Boma, so get in early.

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.
