Table - best surf conditions forecast for Fish Boma over the next 16 days.
Alright, this is Rusty with the same rundown in old-school numbers.
We start on Saturday the 11th of July with a good solid 8ft SSW groundswell at Fish Boma, a reef break. The period is 12 seconds, which gives it punch, and the combined energy is 2047. The wind is a light cross-off from the east, so the surface is clean. This one is for the experienced surfers. Water temp is about average for the season.
Sunday the 12th brings a smaller 5ft SSW swell, still clean. Monday the 13th goes glassy with a 5ft ESE swell, but the period drops to 8 seconds, so it’s a bit softer. Still a fun session. Tuesday the 14th stays glassy with 4ft. Wednesday the 15th sees the swell pick up but onshore wind makes it less appealing.
Thursday the 16th has 10ft SW swell with a 14-second period, but the wind is cross-onshore, messy. Friday the 17th morning is glassy with 10ft SW swell and a 12-second period – that’s big and clean, but only if you’ve got the nerve.
Into the second week, Saturday the 18th offers 6ft S swell with a long 13-second period and clean cross-off wind. Sunday the 19th has 7ft from the SSE, also 13 seconds, light offshore in the morning. Tuesday the 21st is small in the morning at 3ft, but the afternoon brings a 4ft SSW swell with a very long 17-second period – a proper groundswell.
The big news is Thursday the 24th of July: 10ft SSW swell in the morning with a 20-second period and energy at 9653, then 13ft SSW in the afternoon at 18 seconds, energy 9701. Experts only. The wind is light but onshore.
The absolute standout is Saturday the 25th of July: 10ft SW groundswell, 16-second period, combined energy of 4033, and clean cross-off wind from the east. The afternoon is just as good at 10ft SW, 16 seconds, energy of 4610. That’s the one to circle on the calendar.
Rusty out.

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.
