The Lowdown

Alright, crew, Rusty here. We’re looking at the Fish Boma reef break over the next 16 days. The water temp is running 58°F, which is about 5°F colder than normal for this time of year – that’s a very unusual cold snap, so you’ll want a good thick wetsuit or even booties if you’re going in.

The forecast kicks off with a bit of a flat start. The first worthwhile surf doesn’t show up until Monday, 24 August. This gap is about 2 days of nothing to write home about. For Monday morning, we’ve got a 5ft swell from the SW at 12 seconds, but with glassy conditions, it’ll be clean as a whistle. The combined energy is moderate (704), so it won’t be pumping, but those clean lines make it a great option for intermediate surfers. That’s a good little session.

The real standout, though, is Thursday, 27 August. It’s a double-header. We’ve got a 6ft SSW groundswell at 12 seconds in the morning and a 5ft SSW swell in the afternoon – combined energy is strong (1509 and 1272) – and both sessions are glassy with zero wind. This is excellent for experienced surfers. The long period (12 secs) means it’ll be a clean, well-shaped reef wave, and being a reef break, it’ll handle that period nicely. Keep in mind, the swell direction is slightly off the optimum (SSW vs the ideal S), but the quality of the conditions makes up for it. Get out there.

Moving into the second week, things get promising but less certain. Tuesday, 1 September morning looks like a glassy 8ft SW swell at 13 seconds – combined energy is very strong (2436). That’s a serious swell that could be the best of the run if the wind stays true. It’s for experienced surfers only, as it’s well over the 8ft mark.

The big date to circle on your calendar is Friday, 4 September. There’s a massive 16ft SW groundswell predicted with a very long 14-second period and glassy conditions. The combined energy is off the charts at 19636. The report says the swell is predicted to be too big for this break, so unless you’re a pro on a gun, stay out of the water. It’s more of a spectacle than a session for regular folks. After that, the wind picks up on the 5th and 6th, making it choppy and messy.

There are other days with surf, like the 30th and 31st, but the wind is cross-on and the conditions are choppy, so it’s not worth rushing for. Keep an eye on the first week for the best windows.

Stay salty,
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.
