The Lowdown

G’day, Rusty here. We’ve got a solid 16-day window on the cards at Fish Boma, but it’s not all smooth sailing. The opening’s a bit rough, but there’s some absolute gems tucked in there if you’re patient.

The first couple of days, Sunday the 6th and Monday the 7th, are all about size. Sunday morning we’re looking at 8ft of SSW groundswell with a 19-second period—that’s proper long-period energy, packing a massive 4932 combined energy. The wind’s a cross-off at 16 mph, so it’ll be clean, but that size is serious. 8ft with that kind of power is for experienced surfers only. The water’s about average for this time of year, nothing wild. Monday morning drops a touch to 7ft from the same SSW direction, with a 14-second period and 2879 combined energy, and the wind goes silky—3 mph cross-off. That’s a standout morning for those who can handle it. The reef at Fish Boma is exposed to the south, so it’s catching all that energy. Crowds are possible, but with that size, it’ll thin out the pack.

Tuesday the 8th eases right off. Morning brings 5ft from the E with a short 9-second period and 707 combined energy, backed by glassy cross-off wind. It’s clean, small, and fun for a mellow session. The swell direction isn’t ideal for the optimum south, but it’s still rideable.

Now, from Wednesday the 9th to Friday the 11th, we get a bit of a mixed bag. Wednesday is poor—2ft and 3ft, onshore winds, and weak energy. Thursday the 10th is where it picks up again. Thursday afternoon is a real highlight: 8ft of SSW groundswell, 15-second period, 2830 combined energy, and clean cross-off wind at 9 mph. That’s excellent for experienced surfers. Friday the 11th keeps it going with 6ft in the morning and 5ft in the afternoon, both clean and cross-off, great conditions.

Saturday the 12th and Sunday the 13th get messy. Saturday has cross-on wind and rain showers, but the swell is still solid—7ft to 7ft with 15-16 second periods. The energy is there (3540 combined on Saturday afternoon), but the wind’s not cooperating. Sunday the 13th is similar, with a 10ft swell in the afternoon but a short 7-second period, which is a bit junky.

Monday the 14th is a beauty. Monday morning: glassy conditions, 5ft from the SW, 13-second period, 1352 combined energy. That’s a clean, rippable morning for intermediates.

Then we hit a rough patch. Tuesday the 15th has onshore wind, and Wednesday the 16th is a write-off—19 mph cross-on wind, 10ft to 12ft of lumpy, poor surf. Thursday the 17th and Friday the 18th are marginal, with solid size (10ft and 8ft) but cross-on or onshore wind. The energy’s still high, but you’ll be fighting the chop.

The best of the second week? Saturday the 19th morning. Glassy, 5ft from the SSW, 11-second period, 656 combined energy. It’s clean, small, and a perfect morning for a quiet paddle. Just watch out—Saturday afternoon the wind cranks up to 19 mph cross-off, and the swell drops to 5ft, so it’s a one-trick pony.

Sunday the 20th is small and glassy again, 3ft, but the energy’s weak. And Monday the 21st closes out with 8ft of SW windswell, 10-second period, but cross-on wind at 9 mph. It’s there, but not clean.

The standout pick for the whole window is Monday the 7th morning, with that 7ft clean, cross-off SSW groundswell, and the runner-up is Thursday the 10th afternoon, with 8ft and clean cross-off wind. Both are for experienced surfers only. If you’re after something smaller, Monday the 14th morning is glassy and friendly.

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.
