The Lowdown

Alright, Rusty here. Let's break down what's on the table for the next couple of weeks.

Alright, to be honest, Fish Boma is going to be a bit of a mixed bag over this 16-day window. We've got some serious energy coming in, but the wind and conditions are going to make you work for it. The water is much colder than normal for this time of year at 58°F, so you'll want a good winter suit.

The first few days, from Wednesday the 16th through to Friday the 18th, are pretty average. We’ve got some solid, chunky swell in the 6 ft to 8 ft range from the SW on a long 14-second period, but the cross-shore winds are howling at 12-19 mph, turning things into a lumpy, choppy mess. The combined wave energy is moderate to strong (2424), but the quality just isn't there. Not worth paddling out for.

Things start to turn around on Saturday the 19th. The morning drops to a cleaner 5 ft with a light cross-offshore breeze, and the energy is still decent (1150). Then, Saturday afternoon is a real standout. The swell bumps back up to 7 ft from the east with a short, punchy 8-second period. The wind goes light and cross-offshore, making for some surprisingly clean waves compared to the previous days. That's your call for a good session this week.

Sunday the 20th is another one to watch. The morning is a bit messy with cross-shore winds on a 7 ft SW swell, but the afternoon goes dead glassy. Zero wind, clean lines on a 6 ft SW swell with a great 13-second period (1586 energy). That’s as good as it gets for Fish Boma; you’ll have the place feeling like a different spot.

There’s a real flat spell from Monday the 21st through the middle of the following week. Swell drops right off to 4 ft – 4 ft with poor wind, just a quiet patch for the ocean.

But hold onto your board, because the real event of the forecast window is on Thursday the 24th of September. The afternoon swings in a beast of a SW groundswell, hitting 10 ft with a very long 14-second period. And here's the kicker: the wind goes completely glassy again. The wave energy is pumping at 3395, which is very strong. Now, a 10 ft swell is expert territory, and the direction is on the money for the reef. That’s a powerful, clean session for the experienced crew. The morning of the 24th is a write-off with strong cross-onshore wind, so don't even bother until that afternoon glass-off.

After that, we've got a few more mixed days into the end of September and start of October. The 27th of September has some more decent glassy conditions in the morning and afternoon on a 7 ft SW swell, offering another clean window. The very end of the period into October 1st drops right off again as the swell runs out of steam.

If you're picking one, it's the Thursday 24th of September afternoon session for the serious crew, or that glassy Sunday the 20th for a solid, clean experience. Everything else is a case of chasing the windows.

- 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.
