The Lowdown
Alright folks, Rusty here. Let's take a look at what we've got coming down the pipe at Fish Boma. It’s a reef setup exposed to the south swell, and right now it’s a bit of a mixed bag.
The water’s sitting at 59.7°, which is a touch colder than normal for this time of year, so you might want to pull on the steamer. The next couple of weeks have a few windows of opportunity, but we’ve got to wade through some challenging conditions to get to them.
For this Monday (14th September), it's a bit of a write-off. We’ve got a solid 6.9ft swell from the ESE at 10 seconds, but the wind is onshore and the energy is weak for the size (1280). It’s just not happening.
Tuesday the 15th is where things start to look up. Tuesday morning is the first real standout. The swell drops to 5.2ft from the east at 11 seconds, but the wind goes glassy – dead calm. That’s going to make for some clean, peeling lines. The combined energy is moderate at 884. It’s not a huge swell, but with those conditions, it’ll be fun and workable for an intermediate. Afternoon turns a bit bumpy as the breeze swings cross-onshore.
Wednesday the 16th sees a big pulse of energy. The combined energy jumps to 2818 on Wednesday morning with an 8.2ft SW groundswell at a very long 14-second period. That’s a lot of power, and this is big enough that it’s only for experienced crew. The problem is the wind is a strong cross-onshore, so it’ll be choppy and hard to manage. The following days through to Friday the 19th are all in that same vein – plenty of swell (often over 6.6ft) but the wind is cross or cross-off, and often strong (18-22 mph). It’s going to be lumpy and bumpy. The 13.1ft swell on Saturday the 19th afternoon (3513 combined energy) is massive, but it’s also messy.
We hit a real lull on Sunday the 20th. The wind is onshore and howling, and the surf is poor. That carries through to Monday morning.
The next real standout comes on Monday the 21st of September. The afternoon session is pure magic. The swell is a modest 4.3ft from the SW at 12 seconds, but the wind goes glassy again. Absolutely perfect conditions for a reef break. The combined energy is moderate at 931. It won't be huge, but it’ll be clean, lined up, and a joy to surf. Keep in mind this spot can get a crowd "sometimes", so with conditions this good, expect a few others in the water.
Tuesday the 22nd offers a clean afternoon with a cross-off breeze and a 5.6ft SSW groundswell at 13 seconds, but the energy is still moderate (1784).
The last big call is Monday the 28th of September. This is another genuine standout. Both the morning and afternoon sessions are looking excellent for experienced surfers. We’ve got 7.5ft from the WSW at 9 seconds and 7.2ft from the SW at 9 seconds, with a clean cross-off wind. The combined energy is strong (1801 and 1630). This will be a proper session for those who know what they’re doing.
After that, it tails off into smaller, cleaner surf towards the end of the month, but nothing that jumps out as a must-surf.
So, if you’re looking to paddle out, your two best bets are the glassy windows on Tuesday morning the 15th and Monday afternoon the 21st. For the bigger, more powerful stuff, Monday the 28th is the day to circle on the calendar.
Stay safe out there.

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.
