The Lowdown
Alright, this is Rusty comin' at ya from the beach. Let's have a proper look at what's on the menu for the next couple of weeks at Fish Boma.
The surf window opens up on Thursday the 30th of July, but it’s a bit of a slow burn. The first couple of days are there, but not firing on all cylinders. The real magic starts to build from the weekend onward, and there are a couple of absolute standouts that’ll have you calling in sick.
We start with Thursday afternoon, 30th July. The swell is a modest 5.2 ft from the SW, with a solid 13-second period, giving it some proper grunt. The energy is moderate (841), but the wind is a cross-off from the E at 15.5 mph, which keeps things clean enough. It’s a bit of a warm-up lap, nothing to get too excited about.
Friday the 31st shows some promise. The morning session sees the swell bumping up to 5.6 ft from the ESE, with a shorter period of 9 seconds. The energy is moderate (1062) and the wind is a light cross-off. It’s a solid session for experienced surfers. Friday afternoon, the swell jumps to 8.2 ft, but the period drops to 7 seconds, making it a bit of a choppy mess despite the clean wind.
Saturday morning, 1st August, is where things start to get interesting. We’ve got an 8.2 ft swell from the E, period pushing 9 seconds, and the wave energy is strong (2140). The wind is a whisper at 3.1 mph, a light cross-off. It’s clean, punchy, and built for the experienced crew. This is a serious early call.
But Sunday morning, 2nd August, is a true gem. The swell drops a touch to 6.6 ft from the ESE, but the period is a lovely 9 seconds. The energy is strong (1107). The real kicker? Dead calm, glassy conditions. The wind is NW at 0 mph. It’s going to be as smooth as a mirror. For a reef break like Fish Boma, which is exposed to the S swell, having that ESE swell direction with perfect morning glass is a dream. You’ll be trading waves with the locals, but that’s alright. The water is sitting at 63°, which is bang on average for the time of year, so no need for a thick suit.
Monday morning, 3rd August, is another glassy dawn patrol. The swell is down to 4.3 ft from the SW, but the period stretches to 13 seconds, giving it a lovely long, wrapping feel. The energy is still moderate (1104). It’s a smaller day, but perfect for dialing in your turns.
Now, the first week of August is steady, but the real fireworks are in the second week. From the 5th onward, the swell size starts to get serious. Wednesday morning, 5th August, sees a 6.6 ft SW groundswell with a 16-second period (very long) and the energy is very strong (2175). The wind is light and onshore, so it’s not perfect. Wednesday afternoon, the swell hits 9.8 ft, but the wind stays cross-on.
Thursday the 6th holds 9.8 ft SW swell. The energy is huge (3266). It’s big, powerful, and for experts only.
Then we hit the first major standout. Friday morning, 7th August. The swell is 9.8 ft from the SW, period 14 seconds, with a massive 3564 energy reading. The wind is glassy from the NNW at 3.1 mph. This is a big, clean, powerful groundswell hitting a reef. It’s going to be a serious session, but not for the faint of heart. This is a day for the big dogs.
The next standout is Saturday morning, 8th August. The swell pumps to 13.1 ft from the SW, period 15 seconds. The wave energy is a colossal 6014. The wind is a light cross-on from the SSE. This is a beast of a day. The sheer power is off the charts. It’s an expert-only zone, and it’s going to be a spectacle.
There’s a bit of a lull in the middle of the week. Sunday the 9th is still solid at 8.2 ft, glassy in the morning, but the afternoon is a write-off with 18.6 mph wind and rain. Monday the 10th is a wild card: 19.7 ft of SSW swell with 11-second period and a massive 8322 energy reading, but the wind is a strong 25 mph cross-off. It’s going to be a wind-blown mess, but the raw power is insane. This setup might be more interesting for the kite crew than paddle surfers.
The final true standout is Friday morning, 14th August. The swell is 13.1 ft from the SW, period 14 seconds, with a massive 6575 energy reading. The wind is glassy from the SSW. This is as good as it gets for a big swell

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.
