The Lowdown
G'day, I'm Rusty. Let's have a look at what's on the cards for Fish Boma.
The next 16 days are looking pretty darn good, with a solid run of swell coming through, especially for the more experienced crew. The water temperature is about what you'd expect for this time of year, so no surprises there.
The action kicks off on Saturday morning the 18th of July, but it's a bit of a mixed bag. The first session is a bit average with a 4ft SSW groundswell and a light cross-on breeze, making for a messy start. The real standout for the weekend is the Saturday afternoon session. The wind drops to glassy, and the swell builds to a clean 5ft from the SW with a period of 10 seconds. The combined energy is moderate (733), and it's looking like a ripper for a few easy waves.
Sunday the 19th sees the swell jump up, but the wind turns nasty. By Sunday afternoon, it's a messy 10ft SW windswell with a short 8-second period and a fresh cross-on breeze. The energy is strong (1354), but that's way too big and choppy for most, and honestly, looks more like it's set up for a kite session than a paddle.
Monday the 20th is where it gets interesting. The morning is glassy again with a 7ft SW groundswell (11-second period). The energy is strong (1315), and conditions are excellent for experienced surfers. This is a top pick for the week.
The action keeps building. Wednesday morning the 22nd is glassy with a 7ft SW swell and a 13-second period, a solid option for the experienced. But the real showstopper is Friday the 24th of July. The morning is glassy and the swell is a pumping 12ft from the SSW with a very long 16-second period. The combined energy is massive (6098). This is exceptional, expert-level surf. The long period means it'll be powerful and lined up at this reef, but the size and power will be too much for anyone but the most skilled.
The following weekend, Saturday the 25th and Sunday the 26th, still has a big 10ft SW groundswell, but the wind is mostly cross-off or cross-on, keeping it from being perfect. The longer range into the 28th and 29th of July still has some decent swell, but the wind gets a bit more onshore, and by the 30th the swell drops right off. The first week of August sees a fade to smaller, cleaner conditions, but nothing that will get your heart racing.
To wrap it up, the absolute standout is Friday the 24th of July morning for the big dogs. For the rest of us, the Saturday afternoon the 18th and Monday morning the 20th are the best bets for a clean, fun session. The crowds can be there sometimes, so pick your moment.
Rusty.

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.
