The Lowdown
Alright folks, Rusty here. We’ve got a solid 16-day window ahead of us, and it’s all about one spot: Fish Boma. This is a reef break, exposed to the south swell, so it’s going to be the main event. The water's sitting at 63°F, which is bang on average for this time of year, so no surprises there.
The action doesn't really kick off until Thursday, July 16. We’ve got a 8ft SW swell moving in, but the wind is a cross-on mess, so it’s a bit of a write-off. By Friday morning, though, things get interesting. The swell drops slightly to 8ft, but the wind goes glassy, dead calm. The wave energy is strong (1503), and it’s clean. That’s the first real standout for experienced surfers, but it’s still a bit meaty for beginners.
The real magic starts to build toward the end of the week. Tuesday, July 21, is a cracker. You’ve got a 6ft swell from the SSW with a very long 14-second period, glassy conditions, and a solid 1646 energy reading. The waves will have real punch and shape, perfect for a reef break like this. Crowds are only a possibility, so you might get a few sets to yourself.
Now, if you’ve got the skills and the nerve, the period from Wednesday, July 22, through Saturday, July 25, is next-level. The swell jumps massively. Wednesday morning, we’re looking at 16ft of SW swell with a 12-second period and a combined energy of 12389. That’s not just strong; that’s monstrous. This is expert-only territory. The wind is a cross-shore, so it’s not perfect, but the power is undeniable. By Thursday, July 23, it drops to 13ft, but the wind goes glassy again. If you’re good enough, that’s the session of the year.
The standout session, if I had to pick one, is Thursday, July 24, in the afternoon. You’ve got 10ft of SW swell, a 15-second period, glassy wind, and an energy reading of 3884. It’s big, it’s clean, and it’s powerful. For the experienced crew, that’s the one.
The last week of the month settles down a bit. Monday, July 27, still has 8ft SSW swell with glassy conditions in the morning, and the energy is still strong (3046). Wednesday, July 29, is another smaller gem with 5ft of S swell and an 18-second period – that’s a very long period groundswell. It’ll be clean and lined up, but be aware that long period swells can break a bit straight on a reef, so pick your peak.
There are no gaps in the surf here; it’s pretty much continuous from the 16th onward. The first couple of days are a bit messy, but once it cleans up, you’re in for a run of quality.
Stay safe out there, and don’t be a hero if you’re not ready for the big stuff.
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.
