The Lowdown

Right then, let’s have a look at what’s on the cards for the next couple of weeks.

The action is all at Fish Boma, a reef break that’s fairly consistent. Water temp is sitting at 16°, which is about normal for this time of year, so nothing to worry about there.

The swell starts to build on Saturday the 8th of August, but it’s messy. We’ve got a 8ft SW swell with a 14-second period, but the wind is cross-on from the west at 6 mph, and the combined energy is decent at 2190, but the conditions are just marginal. The swell is a bit of a lumpy mess.

Sunday the 9th is a write-off. The swell jumps to 10ft from the SW, but the wind is onshore, strong, and the energy is 2820. It’s a no-go.

Monday the 10th is still poor with strong onshore winds.

Now, Tuesday the 11th of August is where it starts to get interesting. The wind turns cross-off from the east, and we’ve got a 10ft S swell at 13 seconds. The energy is 2852. It’s still a bit on the bigger side, so you’ll want to be comfortable in size, but the conditions are clean. The afternoon drops to 6ft, still clean. This is a solid option.

But the real standout kicks off on Wednesday the 12th of August. The wind is light and cross-off from the ENE, and the swell is a 4ft SSW groundswell with a *very long* 20-second period. The energy is 2037. This is excellent quality, clean surf. The 18-second period swell on the afternoon holds good shape too. This is proper, lined-up, reef-sucking waves. Not huge, but that period is magic. This is your best bet for the week.

Thursday the 13th of August is very similar, with a 6ft SSW swell and a 19-second period, cross-off winds, and energy hitting 4142. The morning session is the pick, with a 5/5 quality rating internally. It’s clean, it’s powerful, and it’s going to be a treat.

Friday the 14th of August is another winner. The wind goes offshore from the NNE at 9 mph, with a 4ft SW swell at 15 seconds. Light offshore, clean faces. It’s a dream.

The second week sees a drop in size, but there are still good sessions. Saturday the 16th of August has a glassy morning with a 3ft SW swell at 14 seconds. The energy is 635, but glassy conditions are a major positive. Then Sunday the 23rd of August is another glassy day with a 4ft SW swell, 14-second period, and 678 energy. A great way to finish the forecast.

The weekend of the 22nd and 23rd is a bit hit and miss, but the 23rd morning is a gem.

So, to sum it up: the best on offer is Wednesday the 12th through Friday the 14th of August. That 20-second, 18-second, and 15-second period swell with clean, cross-off or offshore winds is as good as it gets. Get 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.
