The Lowdown

Alright, Rusty here, checking in with the surf outlook for your spot. Let's get into it.

We've got a bit of a mixed bag coming our way over the next couple of weeks. The pulse of the ocean is definitely going to be felt at Fish Boma (a reef setup), but you're going to have to pick your moments. The good news is, there's some serious energy heading our way, but it's going to come with some challenging winds. The water temperature, by the way, is feeling pretty standard for this time of year, nothing unusual to mention.

We start off on Wednesday the 26th with a solid 5.6 ft groundswell from the South (2541 combined energy), but it's a bit rough and ready thanks to a cross-off wind. The swell bumps up to a meaty 7.5 ft in the afternoon from the SSW (3489 energy), but a stronger breeze will make it a bit jumbled. Not the best quality for paddling right now.

Then we hit the real gem of the short term. Thursday morning, the 27th of August, is where it's at. The wind goes glassy – dead calm – and we've got a clean 6.6 ft SSW groundswell with a nice 12-second period. The combined energy is strong at 1587. This is going to be a morning of clean, powerful lines at Fish Boma, especially for the experienced crew. The crowd factor is a "sometimes" thing here, so get on it early.

Thursday afternoon stays clean with a 4.9 ft S swell, but the wind goes light cross-shore, so it's still rideable, just not as perfect as the glass-off earlier.

Friday the 28th through the weekend (28th, 29th, 30th of August) is a write-off for quality surf. Onshore winds and dropping swell sizes mean it's going to be bumpy and messy. The energy drops right off into the hundreds. You can leave the boards at home.

Now, there's a light at the end of the tunnel. Monday the 31st of August morning brings us back to life. The wind is glassy again, and we've got a 5.2 ft groundswell from the SW (676 combined energy). While the energy isn't massive, those clean, glassy conditions make it a great option. It's a much smaller window, but a promising one.

Things go a bit sideways from Tuesday the 1st of September through Wednesday the 2nd. The swell balloons – we're talking 9.8 ft to 14.8 ft from the SW (combined energy up to 6386). But it's howling cross-onshore. This is a lot of churning white water. At 8.2 ft+ it's expert territory only, and with those winds, it's more of a mess. Honestly, that setup looks more interesting for a kite session than paddle surfing.

We get a brief window on Thursday the 4th of September morning. An 8.2 ft SE windswell (1145 energy) with a short 8-second period, plus a gentle cross-shore breeze. It won't be perfect but it'll be surfable. The afternoon cleans up a bit with a cross-off wind. Friday the 5th of September holds some similar sized, clean-ish surf.

The standout in the second week is Sunday the 6th of September morning. We're back to those glassy conditions, with a solid 6.9 ft S swell (1262 energy). This is another one for the experienced, and those clean faces will be a joy.

After that, the back half of the forecast is a lot more inconsistent and smaller. A few marginal windows, but nothing to get excited about. If you have to pick your battles, that Thursday morning (27th August) and the following Monday morning (31st August) are your best bets in the first week, and then that Sunday the 6th of September morning for the second week. Keep an eye on the long-range, it's always a bit less certain.

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.
