G’day, this is Rusty. Let’s talk about what’s coming up for Fish Boma. This is a reef setup, exposed to swell, and it’s pretty consistent, so there’s plenty to get excited about.
We kick off on Saturday the 4th of July with a solid pulse of swell. Saturday morning we’ve got 7ft of ESE swell at 13 seconds, and glassy conditions with a slight air from the NNW. The water’s sitting at 63°, which is about average for this time of year. The energy’s pumping hard – 1512 (moderate to strong) – and it’s calling for experienced surfers only. This is one of the standout windows. Saturday afternoon stays clean with 6ft ESE swell and glassy wind.
Sunday the 5th drops off a bit to 5ft and 4ft, but still clean with offshore/cross-off and glassy conditions. Monday the 6th sees a direction shift to SW, with 6ft and 6ft – glassy morning, clean afternoon. That moderate combined energy (1113 and 909) still delivers.
Tuesday the 7th holds 6ft and 6ft SW swell, but the morning gets a cross wind. The afternoon turns glassy again – that’s the pick of the day. Wednesday the 8th gets a bit gnarly with 8ft and 7ft SW swell, but cross-on wind and a big energy reading (2126 and 1961) make it a messier option.
Now, the real standout – Thursday the 9th of July. We’ve got 10ft SSW swell at 14 seconds with cross-off wind and clean conditions. The energy’s enormous at 3166. This is big, powerful groundswell – only for the experienced crew. The size (over 8ft) puts it firmly in expert territory. Friday the 10th is still solid at 8ft and 7ft, with clean mornings but stronger ESE wind picking up.
The second week starts to taper. Saturday the 11th has 6ft and 5ft S swell, but ESE wind gets up to 12-16 mph, so it’s cleaner offshore but bumpy underfoot. Sunday the 12th glasss off with 4ft ESE swell – nice fun size. Then we hit a real lull from Monday the 13th through Friday the 17th. Waves drop to around 2ft to 5ft, mostly cross-on or messy, with poor conditions and weak energy. Not worth paddling out.
Things flicker back to life Saturday the 18th of July. We get a 4ft SW swell at 15 seconds – that’s a very long period groundswell. It’s clean with cross-off wind, and 834 energy. This is a promising late window, but it’s a long way out and confidence is lower.
Overall, if you’re keen, Thursday the 9th and that Friday morning the 10th are the best on offer – serious swell with clean conditions. Saturday the 4th is also a cracker. The rest of the first week has plenty of fun, clean moments, but that Thursday is the one to circle.
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.
