The Lowdown
Alright folks, Rusty here. Let’s get into it.
At first glance, it’s a bit of a slow start. The first real action on the cards isn’t until Monday the 20th of July, and even then, it’s only a marginal little 4ft pulse from the ESE. Not worth getting too excited about. But don’t write it off, because this window is set to build into something pretty special.
The standout window is shaping up for Friday the 24th of July. We’re looking at a solid 12ft SSW groundswell with a very long 16-second period. The wind is light and cross-offshore from the East, keeping it clean. This is expert territory – that size (over 8ft) with that much energy (6441) means it’s not for the faint-hearted. Fish Boma is a reef, and that long-period groundswell is going to wrap in beautifully, offering some proper heavy, lined-up waves. The energy is massive, and the conditions are about as good as it gets. This is the absolute best on offer.
Saturday the 25th is still a cracker. The swell drops to 8ft from the SSW, but the wind goes glassy. That’s a major positive. It’s still big (over 8ft) and powerful, but the glassy conditions will make it a dream for experienced surfers who can handle the heft.
After that, we get a few more days of fun, dropping into the 7ft range with glassy spells on Sunday the 26th. Then we hit a rough patch from the 27th to the 29th with strong onshore winds and rain, turning the lineup into a messy, choppy mess. Strong wind and a big swell over a reef? That’s kite-surfing territory, not paddle surfing.
The period from the 30th of July onwards looks promising again. A glassy morning on the 30th with 6ft SW swell, and then the end of the month and start of August is a real doozy. The 31st of July and 1st of August are pumping. The 31st sees an 12ft SW swell building to a massive 16ft with a very long period, and the energy is off the charts (12082). That’s a big, dangerous, expert-only swell. The 1st of August is the pick of that second week: 15ft SW swell, glassy conditions, and a solid 13-second period. It’s a lot of water moving, but if you’ve got the skills, it’s going to be an unforgettable session. Keep in mind, this is a reef, so that long period will be pushing straight and heavy.
The water temp is sitting at 64°, which is pretty much normal for the time of year, so no need to dig out the thickest rubber.
Crowds can be a factor at Fish Boma sometimes, but with the size on offer, a lot of the crew will be watching from the beach.
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.

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.
