The Lowdown
Alright, Rusty here. Let's have a look at what's lined up for us at Fish Boma.
The next couple of weeks look pretty solid, with a lot of action to get your board wet. It kicks off with a bit of a building trend, but you'll want to be picky about the conditions.
The water temperature is sitting at about 64°F, which is about what you'd expect for this time of year. Nothing too crazy, just normal winter temps.
The first decent window is Monday the 20th morning. We're looking at a solid 6ft swell rolling in from the SW, with an 11 second period. This is a nice groundswell, but more importantly, the wind is glassy from the W at just 3 mph. That's a major positive – the lineup is going to be clean. The combined swell energy is chunky at 1127 (moderate), so there's some proper push behind it. Good for experienced surfers looking for a quality session.
Tuesday the 21st morning is the real standout early on. The wind goes dead calm, glassy as anything, with a 6ft SSW swell and a long 14 second period. The energy jumps to 1695 (moderate). That long period means the waves will have some serious shape and power – ideal for this reef setup. It's a bit more advanced, so if you've got the chops, this is your window.
We then get a few days of onshore crud, so wait it out.
The absolute highlight of the whole run is Friday the 24th morning. This is the one. We’ve got an 12ft SSW groundswell with a very long 15 second period. The energy is pumping at 5225 (strong) – that’s serious power. And the wind? Glassy from the ESE at just 3 mph. It's going to be big, clean, and perfect. This is expert territory only – way too big for beginners. If you are an experienced surfer, this is the session.
Saturday the 26th offers a couple of nice windows. Both the morning and afternoon have glassy conditions with a 6ft SW swell around 11-12 seconds. The energy drops back to a manageable 878-924 (weak to moderate). It's a great day for a step down from the Friday beast, still clean and fun with a smaller crowd.
There's a rougher patch mid-week from the 27th with onshore winds, but things clean up again from Thursday the 30th morning with a 6ft SSW swell and clean conditions.
After that, Sunday the 3rd of August morning looks excellent. Light offshore wind from the N at 3 mph, with a 6ft SW groundswell at 14 seconds. The energy is solid at 1307 (moderate). Clean, lined-up waves with no wind messing them up. That's a proper send-off for the forecast period.
So, to keep it simple: if you're skilled, your two best bets are Tuesday the 21st morning for that clean, powerful long-period swell, and the absolute all-star session on Friday the 24th morning for the big, glassy, expert-only bombs.

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.
