The Lowdown
Alright, Rusty here. Let’s talk about what’s on offer at Fish Boma.
We’ve got a bit of a slow start, but stick with me because this reef setup is going to fire. The first few days are pretty average, with light cross-onshore winds and small, short-period swell giving us messy, weak waves. The combined energy is weak, around 378, and the period is only 8 seconds—not much push. You’re better off waiting.
Things start to get interesting on Wednesday afternoon the 15th, when the wind swings onshore from the southwest but the swell jumps up to 5.2ft from the SW with a period of 11 seconds. The energy kicks up to 1365, which is moderate, but the wind is onshore, so it’ll be a bit bumpy.
Now, Thursday the 16th is where it gets good. Morning glass-off, zero wind, and a solid 8.2ft SW groundswell rolling in with a 14-second period. The combined energy is strong at 2705. This is clean, powerful, long-period swell—perfect for a reef. It’s going to be big and only for experienced surfers. The glassy conditions will make it a real standout.
That swell hangs around through Friday the 17th and Saturday the 18th, still with glassy mornings and solid 5.9ft to 7.5ft waves. The energy stays strong. Saturday morning especially looks clean with that calm, glassy surface.
We hit another lull on Sunday the 19th with smaller swell and cross-onshore wind. Not worth the paddle.
Monday the 22nd of July sees a big pulse: 9.8ft to 13.1ft SW swell with a 14-second period. The energy is very strong, up to 5683. But the wind is cross-onshore to onshore, so it’ll be choppy and messy. This is only for experts who don't mind some chop.
The real standout of the whole run is Friday the 24th of July. Morning session: 13.1ft SW swell, 12-second period, clean cross-offshore wind from the east. The combined energy is 5023—very strong. The conditions are described as exceptional for expert surfers. That’s the one to circle on your calendar. Afternoon stays big and clean too at 14.8ft.
Saturday the 25th is still pumping, 11.5ft SSW swell, glassy in the morning. Strong energy. Excellent for experienced surfers.
Sunday the 26th keeps it going with 8.2ft SW swell and glassy morning conditions. Energy still strong at 3633. Another excellent morning session.
After that, the swell fades through the end of July but stays rideable with clean conditions and smaller 4.9ft to 7.9ft waves. The energy drops back to moderate.
So the top two picks: Thursday the 16th for that first big glassy groundswell, and Friday the 24th for the biggest, cleanest, most powerful swell of the run. Both are for experienced surfers only.

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.

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.
