The Lowdown
Alright, let’s get into it for Fish Boma. This is a reef break, open to the south swell, and it’s fairly consistent, so it’ll usually show something. The water temperature is sitting at 60°F, which is a bit colder than average for this time of year, so you’ll want a good wetsuit.
The first few days are a write-off. Thursday afternoon the 3rd has heavy rain and a strong cross-onshore wind from the SSE at 25 mph, turning the 12ft swell into a mess. The combined energy is high at 2193, but the conditions are just poor. Friday the 4th is still ugly with cross-shore winds and lumpy chop on 8ft swell. No good for a paddle.
The first real standout shows up on Saturday morning, the 6th of September. The swell drops to 5ft from the SSW with a period of 11 seconds, combined energy at 688. The wind is cross-shore from the ESE at 12 mph, but it’s only marginal. The real magic is Sunday morning the 6th. We’ve got a 8ft SSW groundswell, period jumping to a very long 19 seconds, and the combined energy leaps to 4449. The wind is cross-offshore from the E at 16 mph, and the wave comment says clean. This is the best of the outlook. That long period from the SSW is perfect for a reef, giving long, powerful lines, and the cross-offshore wind will keep it glassy. It’s solid at 8ft, so it’s for the experienced surfers. Crowds are possible here, so expect some company.
Monday morning the 7th is also a beauty. Clean 6ft swell from the SSW, period 14 seconds, combined energy 2352, and the wind goes glassy from the ESE at 3 mph. That’s an excellent session for the experienced crew. The swell is over 5ft, so it’s pushing into the bigger range, but the clean, glassy conditions make it special.
The rest of the week drops off. Tuesday the 8th has a glassy morning with 5ft swell from the E, but it’s short period at 10 seconds and the combined energy is only 903. It’s a marginal day. From Wednesday the 9th through to Saturday the 12th, the swell drops to under 3ft, the wind turns cross-onshore or choppy, and the scores are low. There’s a gap of a few days with no real recommendations.
The second week sees a pulse. On Sunday the 13th, a clean cross-offshore wind with 6ft SSW swell, period 14 seconds, combined energy 1313, gives a decent but not amazing day. Then Monday the 14th brings a bigger 8ft SSW swell, period 16 seconds, combined energy 3394, but the wind is cross-onshore from the W at 12 mph, making it choppy. The afternoon has an onshore wind, so it’s marginal. That 8ft is only for experts.
The final standout is Thursday morning the 17th of September. The swell is 5ft from the SW, period 13 seconds, combined energy 836, and the wind is glassy from the SSE. That’s an excellent, clean session for intermediate to advanced surfers. The swell is under 5ft, so it’s more accessible.
Overall, the best on offer is the Sunday morning the 6th with that long period groundswell and clean cross-offshore wind. It’s a cracker. The Monday morning the 7th is a close second. The rest of the outlook is a mix of marginal days and a few decent but not perfect windows. Keep an eye on the 17th morning for a glassy 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.
