Righto, Rusty here, let’s break it down.
The next couple of weeks are gonna be a bit of a mixed bag at Fish Boma, a reef setup that’s pretty exposed to the swell. We’re looking at a decent pulse of swell coming through, but the wind’s gonna be the story for most of it.
We kick off on Tuesday, July 7th. Morning is a bit average with a light cross-onshore, but the afternoon turns glassy. You’ve got a solid 6ft SW groundswell pumping in with a 12-second period and the combined energy is chunky at 1037. The water temp is about average for this time of year, so no surprises there. That Tuesday afternoon is the first real standout – it’s gonna be clean and fun for an experienced surfer.
Wednesday, July 8th gets blown out. Stronger cross-onshore winds and the swell jumps up, but the quality goes out the window. Thursday, July 9th is still cross-onshore, but the swell is pushing 10ft. That’s getting big for most folks, better left for the experts.
Now, here’s the second standout of the whole run. Friday morning, July 10th. Glassy conditions, 10ft of SSW groundswell with a 13-second period. The combined energy is massive at 3683. The sets are gonna be packing a punch, and with clean, windless conditions, Fish Boma is gonna turn on for the crew that can handle it. It’s a reef, so that long-period swell is going to line up properly. Expect some crowds here, as it’s a spot that gets attention when it’s this good.
Saturday, July 11th starts glassy again with 7ft SSW swell, but it goes to trash in the afternoon as the wind howls. Sunday, July 12th through Monday, July 13th clean up with offshore winds, but the swell drops off a fair bit – you’re looking at 4ft to 6ft. Still, it’ll be clean.
Tuesday, July 14th is glassy but the swell is small, around 4ft. Then we hit a rough patch. Wednesday, July 15th through Thursday, July 16th is a write-off. Strong, lumpy onshore winds and messy swell. That’s the biggest gap of the forecast; a couple of days you can safely sit out.
Friday, July 17th sees things clean up again but the swell is small. Then, the final push. Saturday, July 18th through Sunday, July 19th, Fish Boma gets another really promising window. Saturday morning is clean with a building 6ft SW swell, and by Saturday afternoon it’s glassy with 8ft. Sunday, July 19th is completely glassy all day, with the morning seeing 8ft SSW swell. That Sunday morning is a real beauty on paper – clean, strong, and consistent. That long-period groundswell is going to reel down the reef.
Monday, July 20th stays glassy with a big 8ft E swell, but that short-ish 9-second period might make it a bit walled-up at a reef. Still, it’ll be clean. After that, the wind turns onshore again from Tuesday, July 21st and the last couple of days look poor.
So, to wrap it up: your best bets are Friday morning, July 10th, and Sunday, July 19th – both days look like they’ll have the size, the power, and the glass to make Fish Boma a proper session.
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.
