The Lowdown

Alright, mate, Rusty here. Let’s break down the next couple of weeks.

Water temp is around 61°F, which is about a degree and a half cooler than usual for the season – a spring suit is a good call.

We kick off with a solid groundswell from the SW, running 5ft with a nice long 16-second interval and a combined energy reading of 1317 – that’s proper power. Early Friday morning, the wind is a light offshore out of the NNE, so Fish Boma (a reef break) is clean and handling that long-period energy well. This is your standout for the opening window – the sets will have a lot of oomph, but this is for experienced surfers at this height. The offshore flow and the long groundswell hitting that exposed reef will give you some great lines. It can get a crowd here, but early should be okay.

Friday afternoon, the wind turns onshore and the energy fades – not much to write home about.

We hit a quieter patch over the weekend. Saturday is smaller with cross-shore breeze, Sunday stays messy until the afternoon. Then Sunday afternoon goes glassy with a light westerly, and the swell is still a decent 5ft (593 energy). That’s a sneaky clean session.

Monday morning is where it really fires up. The swell jumps to 7ft (1659 energy) with a 13-second period and glassy ESE wind – this is going to be pumping. Over 7ft on a reef is expert territory only. Monday morning is a major high point, but watch for the crowds.

Tuesday keeps the size. Morning is glassy with 5ft (982 energy) and flat calm. Tuesday afternoon bumps it to 7ft with more cross-shore – still ridable but not as clean.

Another good window opens Thursday, August 20th, afternoon. The wind goes glass, and we’ve got 6ft of SW swell (922 energy). That’s a clean, powerful afternoon for experienced surfers.

Then things get heavy. Saturday, August 22nd, the swell hits 12ft in the morning, going to 13ft by afternoon. The combined energy rockets to 6324 and then 9465 – that is an extreme, dangerous amount of power. The wind is cross-onshore, so it’ll be messy, but for experts charging, the afternoon is absolutely massive. Expert only.

That big swell sticks around for Sunday and Monday, but the wind stays on it, keeping things rough. By Tuesday, August 25th, it drops to a weak 5ft, then a short-period easterly swell comes in Tuesday afternoon.

The final standout is Saturday, August 29th, morning. The forecast shows a huge 15ft SSW groundswell (very long 15-second period) with clean, slight offshore ENE wind. The combined energy is a monstrous 9375 – that is extreme. This is for experts only, no doubt. It’s almost two weeks out, so it’s a hopeful one, but if it lands, it’ll be the session of the run.

Stay sharp on that reef.

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.
