The Lowdown

Right, folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.

Alright, so we’ve got a bit of a slow start, but things are gonna build nicely. The first real sniff of a wave is on Sunday the 23rd – a bit messy with that cross-on breeze, but there’s a decent 7ft swell from the SW rolling in. The water’s sittin’ at 59°, a good three and a half degrees cooler than usual, so you’ll be wantin’ a thicker steamer. The combined energy of that swell is strong at 1352, so there’s plenty of push.

Honestly, the first few days are a bit of a write-off for clean surfing. The wind is just never quite right. But hang in there, because Thursday the 27th is where it’s at. We’ve got glassy conditions, a solid 6ft SW swell, and the water’s clean. The wave energy is still strong at 1417. That’s the standout of the first week for sure. The next morning, Friday the 28th, is a bit smaller but still okay.

After that, it drops right off. Saturday the 29th is tiny, Sunday the 30th is small and glassy but tiny, and Monday the 31st has a nice window of glassy 4ft waves in the morning that’ll be clean. Then Tuesday the 1st of September has another glassy session in the afternoon with 5ft swell from the SW.

Now, the real excitement is a bit further out – Saturday the 5th of September. That’s the one. There’s a massive 16ft swell from the SW, with a long 16-second period, and the combined energy is a whopping 10989. That’s a lot of water moving. The wind is a gentle cross-on, so it’ll be a bit lumpy but massive. That’s an expert-only paddle, or honestly, it might be more interesting for kite surfing than a normal paddle session. The afternoon cleans up a bit more with 15ft and the wind straight onshore, but it’s still huge. This is the big one, but it’s a long way out, so keep an eye on it.

The tail end of the forecast, from the 6th, is still big but getting messier with the wind. Tuesday the 7th has 10ft SW swell but the cross-on wind is just gonna chop it up.

So, for the best clean, manageable surf, I’m calling Thursday the 27th of August at Fish Boma. Glassy, 6ft, and plenty of energy. That’s your pick.

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. 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.
