The Lowdown
Right then, let’s get into it. The coming weeks have some serious energy headed our way, but you’ll have to pick your moments. Fish Boma is your only play in this region, and it’s a reef setup that demands respect.
The water's currently running at 59°F, which is a good 4°F colder than what you’d normally expect around here this time of year, so you’ll be wanting a decent wetsuit.
We start off pretty average. Monday the 24th of August sees a decent 5ft SW swell, period around 11 seconds pushing in with a combined swell energy of 1048 (moderate energy). Winds are light and onshore from the SSW, so it’s messy. Not worth rushing for.
Tuesday the 25th of August, the swell jumps up to 8ft from the SW, period lengthening to 15 seconds. This is a long period groundswell, combined energy hits 3983 (strong energy). Morning has light onshore winds again, but the afternoon sees a cross-shore from the SE with 6 mph winds, so it’s slightly better but still mixed. For me, the standout window opens on Thursday the 27th of August. Thursday morning we get glassy conditions, zero wind from the SSE, with a solid 6ft SSW swell running on a 12-second period. Combined energy is a strong 1474. This is prime time for experienced surfers – clean, well-shaped waves rolling over the reef. Crowds are sometimes a thing here, so you might have a few out, but that quality will be worth it. If you can’t make Thursday, Friday the 28th also offers glassy conditions in the morning with a 5ft E swell at 10 seconds (970 energy). It’s a bit smaller and softer, but still very clean and surfable.
The end of August and start of September gets a bit iffy again with some onshore winds and building swell. September 2nd sees a big jump: Wednesday morning the 2nd of September has 12ft SW swell, 13-second period, combined energy of 3920 (very strong). But it’s onshore wind, and at that size, this is strictly for experts, and the quality is compromised by the wind. Thursday the 3rd of September is a write-off – massive 20ft to 21ft swell from the SE with rain and strong onshore winds. Combined energy peaks at 10331 (very strong). That is way too big and ugly for paddle surfing; that’s kite territory if anything.
The real standout of the entire 16-day window, however, lands on Saturday the 5th of September. It’s clean, cross-offshore winds from the E at 9 mph, with the swell dropping to a still hefty 12ft from the ESE, period 12 seconds. Combined energy is 3350 (strong). This is going to produce excellent, powerful waves for experienced surfers at Fish Boma. It's the closest we get to perfection in this stretch, so circle that date.
Then on Tuesday the 8th of September, we see a return to cleaner conditions but smaller surf. Tuesday morning offers a clean, light offshore wind from the N at 6 mph, with a 5ft SW swell on a 13-second period (1210 energy). A nice, manageable end to the forecast period for those who want a calm session.
Stay safe out there, and don’t sleep on that 5th of September session.

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.
