The Lowdown

G’day, Rusty here. Righto, we’ve got a solid 16-day window ahead for Fish Boma. This is a reef break, exposed to the south, and it’s fairly consistent. The water’s sitting at 59°, which is a solid 4° colder than normal for this time of year – that’s much colder than usual, so you’ll want a thick wetsuit.

The real standout here is coming, but we’ve got to get through some lumpy days first. The period kicks off Tuesday the 25th of August, with a 2.5m SW swell (15-second period) and a combined energy of 3983, which is very strong. The wind is light offshore in the morning, making for clean waves, but the surf report labels it marginal, so don’t expect perfection. By afternoon, it’s a cross-shore breeze, still big but choppier.

Wednesday the 26th sees the swell drop to 5ft from the south, with a 16-second period and moderate wave energy (2235). Morning winds are cross-offshore, so it’s clean, but the combined energy’s down. Thursday the 27th is a real beauty for experienced surfers – a 6ft SSW swell (12-second period) with glassy conditions in the morning. Zero wind, clean face, and moderate energy (1546). That’s the kind of session you’d paddle out for, but the tide might be a factor. By Friday, the swell fades into the 3-4ft range, and cross-onshore winds come in, turning it messy.

The next true highlight arrives on Friday the 4th of September. Early morning brings a 3.0m SSE swell (10-second period) with glassy conditions and strong energy (3276). This one is for experienced surfers – it’s 10ft, clean, and the wind is dead calm. Excellent surf conditions. Saturday the 5th is a bit smaller at 5ft, but still glassy, and there’s a weird 2ft swell with a super long 22-second period that might be too long and straight for the reef setup.

Into the second week, we’ve got a few promising days. Sunday the 6th of September sees a 7ft SW swell (16-second period) with cross-offshore winds and strong energy (2419) – clean and solid. Monday the 7th is smaller at 4ft, but glassy in the afternoon, making for clean little rollers. After that, it drops off heavily, with poor conditions from the 8th onward – small, choppy, and not worth the paddle.

So, the pick of the fortnight is split: Thursday the 27th of August for a glassy, moderate-sized session, and Friday the 4th of September for the big, clean swell – but that one’s for the crew who know what they’re doing. Crowds can show up here sometimes, so get in early.

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.
