The Lowdown
Alright, Rusty here again. Let’s break down what’s coming for Fish Boma.
The next couple of days are looking pretty average with weak, onshore junk. The first real surf worth paddling for shows up on Thursday the 16th. Water temp is about 17°, right where it should be for this time of year, nothing out of the ordinary.
The absolute highlight is Tuesday the 21st of July. A big, deep groundswell from the SSW rolls in at 13 to 15 feet, with a 15-second period. The energy in the water is massive (7542 to 9259), and it’s glassy calm in the morning. This is a heavy, clean reef break for experts only. The crowd factor is only “sometimes,” so you might get a slice of it if you’re early.
The next standout is Friday the 24th of July. It’s a 12-foot SSW groundswell with a very long 16-second period, and again, glassy conditions in the morning. Another top-tier session for the pros.
After the 25th, the swell eases but there are still clean moments, especially the afternoon of the 25th with glassy 10-foot waves. Then the 27th is a total washout with near-gale winds, so skip that day entirely.
Your best bet: get out for the sunrise session on Tuesday the 21st and Friday the 24th. That’s the real deal.

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.
