The Lowdown

Alright, Rusty here. Let’s talk about what’s coming up for Fish Boma.

Right off the bat, we’ve got a bit of a slow start. The first real action kicks off on Wednesday afternoon, the 12th of August, but it’s not exactly a classic. There’s a 6ft swell from the SSW, but the wind is a cross-off from the east at 19 mph, and the wave energy is strong (3120). The water is sitting at 61°, which is a bit colder than normal for this time of year. It’s a bit of a battle, but there’s potential for a few.

Now, Thursday the 13th is where it starts to get interesting. Thursday morning we’ve got a 5ft SSW groundswell, with a very long period of 19 seconds, and the wind is offshore from the NE at 12 mph. The energy is pumping (4210) and it’s going to be clean. That’s a proper session for experienced surfers. Thursday afternoon the swell picks up a touch to 6ft from the SW, still a long period of 17 seconds, and the wind goes light cross-off from the ENE at 6 mph. The waves will be well-shaped, but that long period means it might be a bit straight at the take-off, so you’ll want to be on your game.

Friday the 14th is a real treat. The morning has a 5ft SW swell with a 16-second period, and the wind is offshore from the NNE at 6 mph. Clean, lined-up waves. Then Friday afternoon turns glassy – a 4ft SW swell with a 15-second period, and the wind goes to glass from the east at 3 mph. That’s the kind of session you dream about. The energy is moderate (1034), but the quality will be top-notch.

The weekend fades a bit. Saturday the 15th and Sunday the 16th see the swell dropping to around 4ft, with shorter periods and cross or cross-on winds. It’s marginal, not worth getting too excited about. That’s a couple of days of small, bumpy surf.

Monday the 17th delivers a bit of a pulse, with a 5ft to 6ft SW swell, but the wind is cross or cross-on, keeping it a little messy. Still, there’s energy in the water (1224), so you might find a few if you’re keen.

The standout, the one you’ve been waiting for, is Sunday the 23rd of August. The morning session is absolutely pumping. We’re looking at an 12ft SSW swell, with a very long period of 17 seconds, and the wind is a light cross-off from the east at 6 mph. The combined energy is massive (7024). This is expert territory only – too big for beginners. The waves will be powerful and lined up, but that very long period might make them a bit tricky at the peak. It’s the best on offer, hands down. Monday the 24th is also very solid, with a 10ft SSW swell, long period of 16 seconds, and light cross-off wind. More big, clean surf for the experienced crew.

After that, the swell drops back down, but there are still a few fun windows. Wednesday the 26th has a 7ft SW swell with a 16-second period, but the wind is cross-on, keeping it from being perfect. Thursday the 27th morning looks glassy with a 4ft SW swell, a nice way to wind down.

So, to sum it up: the best waves of the whole 16-day run are on Sunday the 23rd and Monday the 24th of August. That’s the big, clean, powerful SW groundswell, and it’s for experts only. The next best is Friday the 14th, with those glassy offshore conditions. Don't sleep on it.

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.
