Alright, Rusty here, giving you the scoop on Fish Boma. This reef break loves a good south swell, and it’s wide open to it. The water’s sitting at 63°F, which is about average for this time of year – nothing weird.
The first real action is Sunday the 5th. It’s not huge, but it’s clean. Morning brings a 5ft ESE swell with a 12-second period and a light cross-offshore breeze – the energy is moderate (924). It’ll be tidy. Sunday afternoon goes glassy with a 4ft ESE swell. A gentle, fun start.
Monday the 6th steps up. Morning has a 6ft SW swell (12s) with clean cross-off wind – the energy jumps (1073). That direction is spot-on for Fish Boma. Afternoon holds at 5ft, still clean.
Tuesday the 7th, the swell stays at 6ft from the SW. Morning wind is a bit cross-on, but the afternoon goes glassy. That afternoon glass with a solid 6ft SW swell and strong energy (1013) is a real treat – clean, punchy waves.
Wednesday the 8th gets bigger but messier. The swell hits 7ft from the SW, but the onshore wind and chop ruin it. The energy is high (1826 to 2353), but not worth the fight.
Thursday the 9th is where it gets serious. We’ve got a 10ft SSW swell with a 14-second period and glassy conditions – that’s a massive, powerful groundswell. The energy is huge (3279). This is for experienced surfers only. The long period means long waits, but the walls will be thick.
Friday the 10th is similar – 10ft SSW swell, 13-second period, clean in the morning (energy 3052). Another heavy day for experts. The afternoon gets a 20 km/h cross-shore wind, so get out early.
Saturday the 11th still has a solid 7ft SSW swell (12s) and clean conditions. Energy is still high (1526). A great window for strong intermediate to expert surfers.
It drops off Sunday the 12th with a short-period (8s) SE swell and onshore wind – not great. Monday the 13th is a washout with fresh onshore wind.
We get a reset on Tuesday the 14th. The swell drops to 5ft SE (9s), but it’s glassy and fun. Wednesday the 15th is smaller at 4ft to 3ft.
Then, the big one – Thursday the 16th morning. A massive 10ft SSW swell with a 14-second period, clean offshore wind from the north, and the energy meter goes nuts at 5010. This is exceptional, powerful, and rare. Expert-only, and the long period will make it a dream on this reef. Crowds will likely be there, but it’s the session of the forecast.
Friday the 17th stays solid with 7ft to 6ft SSW swells, clean – excellent follow-up. The weekend of the 18th-19th tails off to smaller, cleaner 5ft to 5ft waves. Monday the 20th finishes with a glassy 4ft S swell.
The two absolute standouts are Thursday the 9th with that 10ft glassy SSW swell, and then Thursday the 16th morning with the colossal 10ft SSW groundswell and perfect offshore wind. Those are the days.
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.
