The Lowdown
Alright, grab your board and listen up, this is Rusty.
We’ve got a solid run of swell on the way for Fish Boma, but you’ve got to be an experienced surfer to really handle what’s coming. The water temp is sitting right around average for the time of year, nothing unusual there.
The action kicks off on Friday, July 31st. The morning session is looking clean with a 4ft swell from the SW, period at 13 seconds, and a light cross-off breeze. The combined energy is a solid 1157 (moderate), so there’s some push. It’s a reef break and it’s exposed, so it’s going to be workable for the experienced crew. The afternoon though, the wind picks up and the swell direction shifts, making it more marginal.
Saturday, August 1st, the morning is the standout. We’re looking at a 8ft swell from the E with a 9-second period, and the wind is a super light cross-off (5 km/h). The energy jumps to 2047 (moderate to strong), and it’s clean. This is the best on offer for the first week. The afternoon drops off a bit.
Sunday and Monday mornings are both glassy with clean conditions. Sunday has a 7ft swell from the ESE with glassy, calm conditions. Monday morning is sweet too, 6ft from the ESE with an 11-second period and glassy conditions, energy at 1305 (moderate). Both are solid options.
Tuesday, August 4th, is a write-off with cross-onshore winds and poor conditions. Skip it.
Now, Wednesday, August 5th morning is a gem. The wind is glassy, the swell is 5ft from the SW with a very long 15-second period, and the energy is 1447 (moderate). That long period groundswell is going to wrap beautifully around the reef, giving you some proper lines. The afternoon gets big and messy.
Thursday, August 6th, is a big day. The swell hits 15ft and 13ft with very strong energy (6334 and 5846). The wind is cross-on, and it’s choppy. This is expert-only territory, and honestly, it might be more interesting for the kite surfers than paddle surfers given the wind and chop.
Friday, August 7th, the morning is back to clean with a 10ft SW swell, cross-off wind, and strong energy (2895). Good for experts.
The real standout of the whole forecast, though, is Wednesday, August 12th. The morning is absolutely firing. You’ve got an 12ft swell from the SW with a 15-second period, and the wind is offshore from the NNE at just 5 km/h. The energy is massive at 4578 (very strong). This is a proper, powerful, clean groundswell hitting the reef perfectly. It’ll be one for the experienced crew only, and it’s going to be a session to remember.
The following days, August 13th to 15th, have some decent swell but the wind is mostly onshore or cross-on, making it messy. The afternoon of August 15th is worth a mention though – glassy conditions with a 10ft SW swell, 15-second period, and energy at 4697 (very strong). A clean, powerful end to the run.
Crowds are possible at Fish Boma, so get in early if you want a piece of it.

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.
