The Lowdown
Alright, surfers, Rusty here. Let’s break down this next stretch of swell for Fish Boma. It’s a reef break that loves a good south groundswell, and boy, we’ve got a run of energy coming our way.
The Overall Picture
We're looking at a solid, persistent run of southwest swell for the next week and a half. It's not going to be giant the whole time, but there are some proper windows of clean, powerful surf to be had. The standout days are definitely the ones with the lighter winds, and we've got a couple of those.
Now, let’s be real. The start of this forecast is a bit of a story. Our first call is Friday, August 7th. Early in the morning, we’ve got a clean 8.2ft of southwest swell rolling in with a 14-second period, and a light ENE cross-offshore breeze. The energy is solid at 2762 – that's a good, strong push. The water temp is at a normal 62.2°F, so nothing weird there. This is a proper start, but it’s a wave for the experienced crew, not the groms.
By Friday afternoon, the swell picks up a touch more energy (3222), the period stretches to 15 seconds, and the wind stays clean out of the east. This is top-notch stuff.
The Weekend Grind
Saturday, August 8th, things get a bit more complicated. The swell is still there, sitting around 7.5ft, but the wind swings around to the west, making it cross-onshore and choppy. It’s not going to be pretty. The energy drops a bit too, down to around 2117. This is a “stay on the beach and watch” kind of day.
Sunday, August 9th, is a write-off. The wind goes full onshore from the SSW, the swell jumps up to 11.5ft by the afternoon, and the energy spikes to a massive 6391. This is all power and no shape. The rain showers won’t help the mood either. Monday the 10th looks much the same – messy and blown out. It’s a lot of water moving around, but zero quality.
The Mid-Week Reset
Tuesday, August 11th, starts to show some signs of life again. The wind goes back to a cross-offshore easterly, cleaning up the 8.2ft of south swell. It’s a bit of a step down in quality from Friday, but the energy is still 2499, so there’s push. It’s a salvageable day if you’re keen.
The Real Standout
Now, listen up, because this is the one. Wednesday, August 12th, we see a new, longer-period swell arrive. The morning shows 4.6ft from the SSW, but with a 20-second period! That’s a serious groundswell. The energy reads 2952, which is heavy for that size. It’s clean with a light ENE cross-offshore breeze. This is a day for the point and reef connoisseurs. You want that long-period energy to wrap and push down the line, and this spot is perfect for it.
Thursday, August 13th, is the absolute pick of the entire run. We've got a beautiful 4.9ft of SSW swell with a 19-second period, and the wind goes offshore from the NNE at just 3 mph. The conditions will be glassy, the wave will be clean, and the energy is still strong at 3292. This is a day you call in sick for. Even though it's not the biggest swell, the combo of size, period, and wind makes it the best quality surf on offer.
Friday, August 14th, is a bit of a letdown after Thursday, with the energy dropping to 1144. It’s still clean in the morning with a 4.9ft swell, but the magic is gone.
The Second Week
Saturday, August 15th, looks fun again. We get a glassy morning with a 5.2ft southwest swell at 15 seconds. Light winds again, so it should be clean and ripable.
Sunday, August 16th is a smaller day, with the swell dropping to 3.6-3.9ft. But don’t count it out. The afternoon turns glassy, and with a 14-second period, it could offer some clean, playful waves for the loggers.
Monday, August 17th is another strong call. The wind goes totally calm in the morning, with 6.2ft of southwest swell at 14 seconds. The energy is back up to 1462. This looks excellent for experienced surfers – another solid, clean day.
Tuesday and Wednesday, August 18th and 19th, see the swell start to fade and the wind turn onshore. we’re looking at 5.2-5.9ft but with cross-onshore winds, so it'll get lumpy.
From Thursday, August 20th, we get a gap of a few days with very little surf on offer, and the energy readings drop below 500. Friday, August 21st brings some rain and building wind, which sets up a stormy weekend with fresh onshore breezes and messy, lumpy conditions.
So, to sum it up: Thursday, August 13th is your day for the best surf. Wednesday the 12th and Monday the 17th are also strong. The first weekend and

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.
