The Lowdown
Alright, this is Rusty, and I’m looking at what’s cookin’ for our local stretch over the next couple of weeks.
Right off the bat, we’ve got a real treat lined up. The first surf we’re looking at kicks off Friday, August 7th, at Fish Boma. This is a reef break, and it’s exposed to the south swell, so when it’s on, it’s on. The water is sitting at 62°F with a negative anomaly of -0.9°F, which is pretty much bang on average for this time of year. Nothing weird going on there.
Friday morning brings a solid 8ft SW swell with a period of 14 seconds, and the wind is ripping cross-offshore out of the east at 9 mph. That’s a dream setup. The wave energy is pumping at 2762 (moderate to strong), and the conditions are clean. This is a setup for experienced surfers—that’s a serious amount of water moving. The afternoon keeps the same energy, period bumps to 15 seconds, and the energy jumps to 3353. It’s still clean. This is a standout window.
Saturday the 8th starts to get a little messy. The swell is still 8ft SW, but the wind goes cross-on in the morning, and the afternoon is choppy. The scores drop right off. Sunday the 9th is a write-off, with 10ft SW swell and onshore winds from the south, rain, and a combined energy of 5602 (very strong). That’s a beast, but it’s a mess. Honestly, that setup on Sunday with the onshore wind and big swell—this is more of a kite surfer’s playground than a paddle surfer’s dream.
Monday the 10th is still a bit rough, but Tuesday the 11th is another cracker. Tuesday morning is 10ft S swell (13-second period), cross-offshore wind from the ENE at 9 mph, and clean. The energy is 3011 (moderate to strong). That’s a heavy day for experienced surfers only. The afternoon drops to 6ft but the wind picks up to 19 mph, so it’s less appealing.
Now, Wednesday the 12th is interesting. The swell is smaller at 5ft SSW, but the period jumps to a very long 20 seconds. That’s groundswell, and at a reef, that’s going to be lined up and powerful. Morning winds are cross-off and clean. The energy is 2248 (moderate). This is a good day for anyone comfortable on a longer-period wave.
But the real gem of the whole run might be Thursday, August 13th. The morning is glassy—no wind, just a slight air at 3 mph from the NE. The swell is 5ft SSW with a 19-second period, and the energy is 3220 (moderate to strong). That’s spooky clean. Expert level, but if you’re on it, it’s magic. The afternoon stays excellent with a 7ft SW swell and 18-second period, cross-off wind, clean. Two standout sessions in one day.
Friday the 14th morning is another glassy one, 5ft SW, 15-second period, clean. The energy drops a bit to 1113, but the quality is still there. The afternoon fades.
Moving into the second week, things get more inconsistent. There’s a decent little run from Sunday the 16th afternoon through Tuesday the 18th, with clean conditions and 5ft SW swell, but the energy is lower, around 1000. The 17th morning is glassy again, which is a nice touch.
After that, the wind gets messy from Wednesday the 19th onward. The 21st Friday has a 8ft SW swell, but the wind is cross-on and choppy, and by the afternoon it’s a poor mess with rain. The 22nd Saturday is pretty flat and windy.
So, if you’re picking your window, Friday morning the 7th and Thursday the 13th are the absolute standouts. The 13th has that glassy morning with a groundswell that will make the reef sing. The 12th is also worth a look for the long period. The rest of the run is a mix of good and average, with a real messy gap from the 19th onwards.
This is Rusty, signing off.

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.
