The Lowdown
Alright, Rusty here, letting you know what’s on the cards for the next couple of weeks. We’ve got one spot to talk about, and it’s a beauty – Fish Boma. This is a reef break, exposed to the south swell, and it’s fairly consistent. The water is sitting at 64°, which is pretty much bang on average for this time of year, so no surprises there.
The forecast kicks off right away. Friday the 17th afternoon is looking tidy with a 7ft SW swell. The wind is glassy, dead calm, and the water is like a mirror. The combined energy is moderate at 952. This is a solid start, but it’s just the warm-up. The real standout is the Saturday morning of the 24th of July. We’re talking a solid 10ft SSW groundswell with a very long period of 16 seconds. That’s a serious amount of energy – 4747. The wind is glassy again, and it’s being called excellent for experienced surfers. At that size, over 8ft, this is one for the experts only. The long period and south direction are a perfect match for this reef, so expect some proper, powerful lines.
Before that, there’s a bit of a mixed bag. The 18th and 19th have some swell, but the wind is a bit messy, cross-on or cross, keeping the quality marginal. The 20th has a glassy morning with a 6ft SW swell, which is a good, clean option for the more experienced. The 23rd of July also has a glassy morning with a 7ft SW swell, another clean one for the crew who know what they’re doing.
After the 24th, the swell stays big into the 25th with a 10ft SW swell in the morning, still glassy and excellent. But then the 26th of July is a write-off – strong onshore wind and a messy 13ft SE swell. That’s more of a kitesurfing day than a paddle day. The 27th and 28th clean up again with some solid SSW groundswell and clean, cross-off winds. The 29th sees the swell drop, but the 30th brings a new E swell with clean conditions.
Overall, the clear standout is the 24th of July. That’s the one to circle on the calendar. It’s a powerful, glassy day for the experts only. The 25th is also a top-tier option. The rest of the window has plenty of other clean, surfable days, but nothing else hits that same peak.
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.

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.
