The Lowdown
Righto, let’s get into it. This is Rusty, and I’m looking at the forecast for Fish Boma. This is a reef setup, exposed to the south swell, and it’s a fairly consistent spot. The water temp is about average for this time of year, nothing weird going on there.
We’ve got a bit of a slow start, but the real action kicks off on Friday, July 31st. That morning, we’re looking at a clean 4ft SW swell, with a light cross-off breeze. The combined energy is solid (1177), and it’s a good one for experienced surfers. The afternoon gets a bit messier with a bigger, short-period ESE swell at 8ft and a stronger cross-off wind, so the morning is the pick of that day.
Saturday, August 1st is a standout. The morning brings a clean 8ft E swell (9 seconds) with hardly any wind, giving you clean conditions. The combined energy is pumping (2047). The afternoon stays clean too, with a 8ft ESE swell. This is a top session for the experienced crew.
Sunday, August 2nd is the absolute gem. The morning is glassy with a 6ft ESE swell, and the wind is dead calm. The afternoon gets even better: glassy, 7ft, with a long 12-second period from the ESE, and the combined energy is strong (1540). That’s a wave that will have shape and power. This is the best on offer right now.
Monday, August 3rd keeps it tidy with glassy mornings and a 5ft ESE swell, but the energy drops a bit.
From Tuesday, August 4th through to Wednesday, August 5th, we get a shift. The morning of the 5th is a bit onshore with a solid 8ft SW swell, but the afternoon of the 5th is a standout. You get a 10ft SW groundswell, with a very long 16-second period, and it’s glassy. The combined energy is huge (3736). That’s a big, powerful, clean swell, but at 10ft, it is only for experts. It’s a point break kind of day.
The 6th and 7th of August keep the big SW swell going, with the 7th morning being glassy again at 10ft, but it’s big. The 8th of August (Saturday) offers a more manageable 8ft SW swell with clean conditions, and the afternoon is glassy. That’s a solid weekend contender.
After that, the swell drops back through the second week, with a mix of clean and choppy days. The 10th of August has a nice glassy afternoon with a 7ft SSW swell. The 11th of August has clean conditions in the morning with a 8ft SSW swell, and the afternoon pumps out a 10ft S swell, but it’s a shorter period.
The 12th of August gets a bit wild with a 13ft SSE swell, but it’s cross-onshore and choppy, so that’s more for the experts who don’t mind a battle. The 13th of August is a write-off with strong winds and rain. The 14th of August cleans up nicely in the afternoon with a 5ft SW swell, and the 15th of August (Saturday) finishes strong with a clean 7ft SW swell and offshore winds.
So, the standout is the glassy, long-period ESE swell on the afternoon of Sunday, August 2nd. The other big one is the glassy, 16-second SW groundswell on the afternoon of Wednesday, August 5th, but that’s expert territory. The whole first week is pumping if you’re in the know.

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.
