Table - best surf conditions forecast for Fish Boma over the next 16 days.
Right, listen up. Rusty here. We’ve got one spot on the radar for the next couple of weeks, and it’s a proper reef setup that’s going to have its moments, but you’ve got to pick your windows.
The pattern starts with a bit of a slow build. Sunday the 12th, we’re looking at a solid 5ft SSW swell rolling in with an 11-second period. The energy is moderate (958), and the wind is coming from the east, which is a clean cross-offshore. This is a decent starting point, but the real standout doesn’t hit until the following week.
Now, the water temp is sitting at 62°, which is about normal for the time of year, so nothing wild there.
The first real standout is Wednesday the 15th in the afternoon. A tiny 3ft wave on the face of it, but the period jumps to a very long 18 seconds. That’s groundswell energy right there, and with glassy conditions, the reef at Fish Boma will be offering up some clean, lined-up waves for the experienced crew. The energy is moderate (1014), but the quality is high.
Then, hold onto your board. Thursday the 16th morning is a big one. An 8ft SW groundswell with a 14-second period, and the energy is strong (2762). The wind is dead calm, glassy. This is for experts only, as it’s over 8ft. It’s going to be powerful and straight on a reef, but clean as a whistle.
The absolute best of the best, though, is the 22nd of July. The Wednesday morning session is an 12ft SSW groundswell with a 14-second period, and the energy is very strong (4494). The wind is a light offshore breeze from the NE. This is the one. Crowds are possible, but for this quality, you’ll be in the zone. The afternoon is just as good, with a gentle offshore keeping it clean.
After that, there’s a bit of chop and cross-shore wind through the 23rd and 24th, but the 24th afternoon turns glassy again with an 8ft SW groundswell. The 25th morning is also worth a mention, with an 8ft SSW groundswell at a very long 16 seconds and glassy conditions. The 26th of July is a monster, with an 18ft swell, but that’s for the absolute lunatics only, and the wind is a bit cross-on, so it’s going to be a handful.
The last week drops off a bit, with smaller swells and onshore winds, so the 22nd is your target.
Rusty.

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.
