The Lowdown

Alright, Rusty here, lookin’ at the next couple of weeks for Fish Boma. This reef loves a south swell, and the water’s about normal for this time of year.

First window is Thursday morning, September 3rd. We got a clean 5ft swell from the southwest, with a 12-second period, and the wind is dead glass. The combined energy is strong (1053). It’s a bit big for beginners, but for experienced surfers, this is a sweet spot. The break is fairly consistent, but expect some company.

That Thursday afternoon goes to hell—heavy rain and a 30 km/h cross-onshore wind ruin the 11ft swell. That’s a kite session.

Sunday, September 6th is a big one. The morning swell is 6ft from the SSW, but the period is a massive 19 seconds. That’s a very long groundswell, and the energy is huge (3360). With clean cross-off winds, it’ll be epic at this reef. The afternoon bumps up to 8ft, still clean, but that’s expert-only territory.

Monday, September 7th is the day to circle. The swell is 6ft from the SSW, period 14 seconds, and the wind is glassy all day. The energy is still very strong (2091 and 1776). This is a classic, perfect reef day.

It gets smaller after that. Wednesday, September 9th afternoon has a tiny 3ft swell with glassy conditions—perfect for a longboard.

Another pulse on Thursday, September 10th with 7ft in the morning, then glassy 5ft in the afternoon. Very good.

The second week is bigger but messier. Sunday, September 13th afternoon has a 10ft swell from the SSW with a 13-second period, but a gentle cross-shore wind will make it a little bumpy. That’s for experts.

Monday, September 14th is 11ft from the east with a short period and cross-onshore wind—choppy and big. Kite territory.

Tuesday, September 15th afternoon brings a glassy 4ft from the east. Short period, but clean and fun.

Thursday, September 17th is a total washout with 15ft of swell and 35 km/h winds.

The standout is Monday, September 7th—glassy, 6ft, powerful SSW groundswell at Fish Boma. Second best is Sunday, September 6th morning with that 19-second groundswell. Get it while it’s clean.

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.
