The Lowdown
Alright, Rusty here, let’s get into it.
We’ve got a solid run of surf coming up at Fish Boma, a reef break that’s fairly consistent and exposed to the south. The water’s sitting at 63°, which is bang on average for this time of year, so no shock to the system there.
The real headline is the end of the month. Saturday the 25th of July is the standout. That morning, we’re looking at a deep, long-period SSW groundswell pushing 13ft with a period of 18 seconds – that’s a proper pulse of energy (10,670 combined energy). And it’s dead calm, glassy conditions. This is exceptional surf for expert surfers only. It’s going to be big, powerful, and lined up beautifully on the reef. If you’ve got the skills, that’s the session you wait for.
Before that, Thursday the 23rd of July morning is a strong option. Clean conditions with offshore E wind, swell around 15ft from the SW (7,074 energy), a bit more manageable but still solid for experienced surfers. The period is 14 seconds, so it’s a proper groundswell that will hold its shape well.
The middle of the run has some good windows. Tuesday the 21st of July morning is glassy, with a 6ft SSW swell and a very long 15-second period. That’s a lot of energy for the size (1,664 energy), and the reef will love it. Friday the 17th of July morning is also glassy, with 8ft SW swell and 12-second period – clean and punchy for experienced surfers. Thursday the 16th of July morning is a good warm-up: glassy, 8ft SW swell, but the period is a touch shorter at 14 seconds. Still excellent for experienced surfers.
Now, the caveat: this is a reef break, and when the swell gets big, especially over 8ft, it’s not for beginners. The 18-second period on the 25th means long lulls between sets, but the waves that do come will be thick and powerful. The break is also a bit exposed, so when the wind swings cross-on or onshore, it gets messy. You’ll see that on the 22nd of July, when a 13ft SW swell gets hit by a 15 km/h cross-on wind – that’s more of a kite-surfing show than a paddle session.
Crowds can pop up here sometimes, especially on the glassy mornings, but given the size of the swell on the best days, it’ll thin out the pack to only the keen and capable.
There’s a gap in quality after the 25th, with the last week of July seeing smaller, more wind-affected waves. The 31st of July morning offers a last chance with 8ft SW swell and clean offshore wind, but it’s not in the same league as earlier.
So, bottom line: the absolute best is Saturday the 25th of July morning. Mark it. The second best is Thursday the 23rd of July morning. Get on it.

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.
