The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got one spot on the radar for the next 16 days, and it’s all about Fish Boma. This reef break is exposed to the south swell, and it’s about to get a solid run of south-west and south-south-west groundswell. The water temp is sitting at 62°F, which is about normal for this time of year, nothing weird going on there.
The first real action kicks off on Thursday, 6th August. The morning sees a solid 10ft SW swell rolling in with a 13-second period, but the wind is a cross-on from the WSW at 9 mph, making it a bit choppy and messy. The combined energy is pumping at 3445, but the conditions are marginal. The afternoon is similar, with the same size swell and a lighter cross-on breeze, but still not clean. This one’s a pass for the paddle.
Friday, 7th August, is where it starts to get interesting. The morning brings a clean, cross-off offshore breeze from the east at 9 mph, with 8ft SW swell and a 14-second period. The energy is still strong at 2762. This is quality surf for experienced surfers. The afternoon bumps up to 10ft, 15-second period with a clean cross-off again, and the energy hits 3869. This is the standout of the first week. The swell direction is SSW, matching the optimum S direction nicely, and the offshore wind will keep it lined up.
Saturday and Sunday (8th and 9th August) are a write-off. Saturday morning has a strong cross-on wind from the west at 12 mph making a mess of the 8ft swell, and Sunday gets slammed by onshore winds and rain. The swell gets up to 12ft on Sunday afternoon, but with onshore winds hitting 19 mph, it’s a complete no-go. That’s kite-surfing weather, not for the paddle.
Monday, 10th August, is still messy with rain and cross-on winds, so we’ll skip that.
Tuesday, 11th August, brings a return to form. The morning has a clean cross-off breeze from the ENE at 9 mph, with 8ft SSW swell and a 12-second period. The energy is moderate at 1873, but the conditions are clean and excellent for experienced surfers. The afternoon is a bit windier with a fresh breeze, so the morning is the pick.
Now, Wednesday, 12th August, is a real treat. The morning has a light cross-off breeze from the ENE at just 6 mph, with a 5ft SSW swell. But the period is a massive 20 seconds – that’s very long-period groundswell. The energy is still moderate at 2039, but the shape will be incredible. This is a reef break, so it’s perfectly suited to handle that long period. The afternoon holds 6ft, 18-second period, still clean. A standout for the mid-week.
Thursday, 13th August, is looking glassy. The morning has a glassy, offshore wind from the north at just 3 mph, with 7ft SSW swell and a 17-second period. The energy is strong at 2827. This is as good as it gets – clean, glassy, and a solid groundswell. The afternoon is clean too, with a cross-off breeze. This is a top contender for the best session of the entire forecast.
Friday, 14th August, the swell starts to drop. The morning is still clean with a light offshore wind, but the swell is down to 4ft. The afternoon gets a bit crinkly with a cross-shore wind.
The second week (15th August onwards) is a mixed bag but still has some gems. Saturday, 15th August, is clean in the morning with 4ft, 17-second period, and a glassy afternoon with 4ft. The energy is low, but the conditions are perfect. Sunday, 16th August, is smaller and onshore, so skip it.
Monday, 17th August, is another standout. The morning is glassy with 5ft, 12-second period, and the afternoon is glassy with 7ft, 15-second period. The energy jumps to 2655 in the afternoon. That’s a solid, clean, glassy afternoon session. Tuesday, 18th August, is glassy in the morning with 6ft, 14-second period.
The rest of the week (19th to 21st August) sees the swell holding but the winds turning more cross-shore and onshore, with some rain and strong winds on the 21st. The morning of Thursday, 20th August, is a notable mention: 8ft, 12-second period with a light cross-shore breeze, but it’s not as clean as the earlier windows.
The Best on Offer: The morning of Friday, 7th August, and the glassy morning of Thursday, 13th August, are the true standouts. Friday has the size and clean offshore wind, Thursday has the glassy perfection with a long-period swell. Both are for experienced surfers only. Fish Boma can get crowded sometimes, so expect company on those days.

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.
