The Lowdown

G’day, Rusty here with a look at what’s coming up over the next couple of weeks at Fish Boma.

We’ve got a solid run of swell on the way, but the first few days are a bit sketchy with the conditions. Saturday 15th looks miserable – lumpy cross-shore chop and only waist-high, not worth paddling out. Sunday 16th shows some improvement in the afternoon when the wind drops to glassy and those 4ft SW groundswells clean right up – that’s a sneakily good session if you can time it right.

The real action starts Monday 17th when the swell builds to 7ft from the SW, but the wind is still messy. Tuesday 18th morning is where we get the first standout: the swell is a solid 7ft, the wind is glassy, and the wave energy is already strong (1392). That’s a clean, powerful southwest swell with a nice 13-second period – perfect for this exposed reef setup. Expect some proper corners and hollow sections, and with the water temp sitting at 57°, that’s about 6° colder than normal for this time of year, so it’s unusually frigid – don’t forget the steamer.

Wednesday 19th delivers another gem – morning and afternoon both glassy, with 8ft to 8ft SW swell, long 12-second period, and strong wave energy (1768 and 1509). This is the heart of the window: clean, powerful, and consistent. The crowd factor is “sometimes” so you won’t have it to yourself, but it won’t be a zoo either. Thursday 20th afternoon and Friday 21st keep that quality rolling with glassy conditions and 8ft to 7ft SSW swell – Friday afternoon is dead calm, zero wind, and the wave energy’s still high (1474). Absolute bliss.

Saturday 22nd gets messy again with cross-onshore wind kicking up chop, but Sunday 23rd morning is another glassy window with 8ft SSW swell and massive energy (2055). That’s a heavy one – only for experienced surfers at that size. Then Monday 24th morning is the pick of the whole run: 10ft SSW swell with a very long 16-second period, glassy wind, and wave energy through the roof at 4272. That’s proper groundswell, and on a reef it’s going to produce some long, fast, powerful lines. Experts only, and worth blocking out your calendar.

The second week starts to fade a little. Tuesday 25th morning still has clean 6ft SSW swell, but the period drops back to 12 seconds and energy is moderate (1099). Wednesday 26th is blown out with moderate cross-onshore wind, and while there’s an 8ft SW swell with a 16-second period in the afternoon, the chop makes it a struggle. Thursday 27th and Friday 28th see conditions deteriorate further – Friday is downright poor with moderate onshore wind and weak 4ft swell (420 energy). Saturday 29th and Sunday 30th show some improvement in swell size but the wind stays onshore, so it’s marginal at best.

If you’re looking for the real standout, Monday 24th August is the absolute peak – that 10ft, 16-second SSW groundswell with glassy conditions is as good as it gets. Tuesday 18th and Wednesday 19th are your safe bets earlier in the run. Everything else is either blown out or getting small again. Don’t waste your time on those first couple of days – just wait for the clean windows and you’ll be smiling.

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.
