The Lowdown
Alright, Rusty here. Let’s talk about what’s shaping up.
We’ve got one spot on the radar for the next couple of weeks: Fish Boma. It’s an exposed reef break, and it’s fairly consistent, so it’s got some potential. The water temp is about average for this time of year, nothing too unusual.
The first few days are a bit of a mixed bag. Monday the 20th kicks off with a 6ft SW swell, but the wind is cross and conditions are only marginal. Not worth getting too excited about. The afternoon goes glassy with a 4ft ESE swell, but the energy is moderate (868) and the wave comment is “expect very good surf conditions,” so it could be a sneaky clean session if you’re patient.
Tuesday the 21st is where things start to get interesting. The morning is glassy again, with a solid 6ft SSW groundswell (14-second period) and strong wave energy (1829). This is excellent for experienced surfers – the water will be clean, and that long period means the reef will handle it well. The afternoon gets bigger at 8ft, but the wind turns cross-on, so it’ll get lumpy. Only for the keen.
Wednesday the 22nd and Thursday the 23rd are mostly cross-on and choppy, with moderate energy. Thursday afternoon sees a 10ft SW swell, but a moderate breeze and choppy conditions make it a tough one. Not recommended.
Now, here’s a standout. Friday the 24th morning. The swell jumps to 12ft from the SSW with a very long 15-second period. The combined energy is a massive 5089 – that’s strong. The wind is light and cross, so it’ll be a bit lined up. This is expert territory, no question. The reef will be firing, but it’s going to be a heavy, powerful wave. Saturday the 25th keeps the swell around 8ft to 8ft, but the wind stays cross, so it’s still marginal.
Sunday the 26th is a glassy day with a 6ft SW swell – clean and smooth. A good one for intermediate surfers. The energy is moderate (947), but the glassy conditions make it a real treat.
The first week of August is a letdown. Monday the 27th through Friday the 1st of August are mostly blown out or choppy, with poor conditions. The swell drops off significantly. It’s a real gap.
But hold on. The best of the whole outlook is Tuesday the 4th of August. The morning is glassy, with a 10ft WSW swell and a 14-second period. The combined energy is a massive 6742 – that’s very strong. This is exceptional for experts. The wind is off, the swell is big and long, and the reef will be handling it beautifully. This is the one to circle on the calendar.
So, the first week is a bit of a tease, with a few good windows, but the real standout is that Tuesday the 4th morning. It’s a long way off, so things can change, but if it holds, it’s going to be a special session.
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.
