The Lowdown

G’day, Rusty here. Let’s break down what’s cookin’ at Fish Boma. This is a reef break that’s fairly consistent and gets the south swell. Water temp’s about 59°, so that’s a noticeable chill – nearly two degrees colder than usual for this time of year, so you’ll want a wetsuit.

First few days? Rubbish. From Tuesday through Friday, there’s plenty of swell – 8 ft to 12 ft – but the wind’s all over the place. Onshore and cross-shore, strong at times, with wave energy high (1609 to 2831 combined). Thursday afternoon’s a disaster with 25 mph winds and heavy rain. The swell period is 12-13 seconds early on, solid groundswell, but the wind’s just smashing it. Friday is still messy with 8 ft to 7 ft from the SE and fresh cross-shore winds.

Now, a bright spot. Saturday morning the 5th of September – swell drops to 4 ft from the SSW with an 11-second period, light cross-offshore winds from the east, and it’s clean. Combined energy is moderate at 617. It can be a bit inconsistent here, but when it’s clean it’s fun. Crowds can show up sometimes, so don’t expect solitude.

Sunday the 6th of September is the one. Morning brings 8 ft from the SSW with a very long 17-second period – that’s proper groundswell, powerful, long waits between sets. Combined energy hits 3670. Offshore east winds keep it clean. By afternoon, it’s 10 ft with a 19-second period and a massive 7290 combined energy – that’s big, heavy, expert-only territory. The swell direction lines up perfect with the south swell, and the reef will handle that long period, giving you some beautiful lines. If you’ve got the skills, this is your day.

Monday the 7th stays good – 6 ft from the SSW, 13 seconds, light offshore winds from the NE, clean. 2619 combined energy. Good for strong intermediates.

From Tuesday the 8th, the swell fades. 5 ft from the east, 10 seconds, light offshore winds – clean but weak (715 combined). Then from Wednesday the 9th, it goes flat. Swell down to 2 ft-3 ft, barely any energy, under 300 combined. That lasts until around the 11th when we see a little bump Friday afternoon – 7 ft from the ESE but short period (8 seconds) and cross-shore wind. Not great.

A little hope later on. Monday the 14th of September brings 4 ft from the SW with glassy conditions in the afternoon – clean, tiny, good for a longboard. Tuesday the 15th picks up again: 6 ft to 7 ft from the SSW, 12 seconds, light offshore winds, clean, 1188-1260 combined energy. Another solid window for experienced surfers, especially the afternoon.

So bottom line: this week’s mostly a dud. Saturday morning the 5th is a small clean session, but Sunday the 6th is the standout – big, clean, powerful. After that, you’re waiting a week until the 14th and 15th for another chance. Forecasts can change, so don’t write it off completely.

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.
