The Lowdown
Alright folks, Rusty here with a look at the upcoming waves. We’ve got a solid run of surf on the cards, but let’s get into the nitty-gritty.
The forecast period kicks off on Thursday, July 30th, with some decent, strong groundswell, but the wind is a bit of a spoiler. The swell energy is solid and punchy (1515), but with a moderate cross-off breeze, it’ll be a bit choppy.
We start to really clean up on Saturday morning, August 1st. It’s glassy at dawn (1098), with a 8ft swell from the ESE. The period drops to 9 seconds though, so it’s a bit short-period and gutless compared to what’s coming. Sunday morning, August 2nd, builds on that with clean 7ft surf (1040) and zero wind. Nice and clean.
Now, here’s where things get interesting. The standout period begins on Wednesday afternoon, August 5th. The wind goes totally calm, and a new 8ft groundswell from the SSW with a long period of 15 seconds arrives, pumping in at 3154 combined energy. The water temperature is about average for this time of year.
Thursday, August 6th, sees that swell continue but with a messy cross-on wind, so it’s not the pick. But hold on for Friday, August 7th. The morning brings an expert-only 12ft groundswell from the SW with a 15-second period and a light cross-off breeze. The energy is massive (5743), and for experienced surfers, it’s going to be a proper session.
The real blockbuster, though, is on Sunday, August 9th. That’s the one to mark in the calendar. The swell jumps to 16ft on the Sunday morning and 20ft in the afternoon. The energy readings are off the charts (8905 and then 13170), with long-period SW groundswell, dead calm glassy conditions, and the forecast is rating it as exceptional. This is heavy, powerful, and very clean. Only for the well-experienced and those with big-wave boards. The clean conditions string into Monday, August 10th, with a 13ft swell and a light cross-off wind before it eventually backs off.
After that epic run, the surf hangs around. Tuesday, August 11th, still sees a 10ft SW groundswell, and the glass-off on Wednesday and Thursday mornings (August 12th and 13th) provides clean, smaller waves in the 5ft to 8ft range. The final Friday, August 14th, finishes the forecast with a clean, small 4ft swell offering ideal beginner-friendly waves or a mellow session.
If you can only pick one, go for the Sunday the 9th. The combination of size, power, and absolute glass is a once in a 16-day window type of deal.
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.
