The Lowdown

G’day, Rusty here. Let’s break down what Fish Boma has in store for the next couple of weeks. It's a reef setup, exposed to the south, and the water’s at 62°, pretty normal for this time of year. No crazy anomalies.

Right off the bat, Monday’s a mess – rain showers, cross-onshore wind at 12 mph, and a lumpy 10ft swell with a short 11-second period. Combined energy’s moderate at 1935. Not the way you want to start. Tuesday’s a bit better – the wind turns east, cross-off at 12-16 mph, and the swell drops to around 7ft in the morning, down to 6ft by afternoon. Still flagged as marginal, so you’ll have to work for it.

Now, Wednesday the 12th is where things get interesting. The swell period jumps to 18-20 seconds – that’s proper groundswell. The energy’s climbing, 2553 in the morning and up to 3301 in the afternoon. It’s clean with that east breeze, and the swell’s around 5-6ft. Not huge, but that long period means real push. This is shaping up.

Thursday the 13th is the clear standout of the first week. Morning brings a NNE offshore at 16 mph, clean conditions, and 5ft of SSW swell with a 19-second period. Combined energy is cranking at 4149. That’s the day. The afternoon’s a touch bigger at 7ft, still clean. If you can get out, this is it.

Friday the 14th holds some of that – light offshore winds, 5ft in the morning, 4ft in the afternoon, with 15-16 second periods. Clean and glassy. Saturday and Sunday fade though – the swell drops to 4ft, the wind turns cross-onshore or glassy, and the energy plummets to 656-704. Not worth the paddle.

Then Monday the 17th brings a second pulse – 7-7ft from the SW with a 16-second period. Cross-off winds in the afternoon keep it clean. Energy’s back up to 2537. Tuesday the 18th is poor – choppy and cross-onshore, energy under 1200. Wednesday’s marginal, but Thursday the 20th brings a fresh east breeze, 8ft of ESE swell, but only an 8-9 second period. That’s short-period wind swell – messy and less powerful.

Now, the long-range one to circle is Friday the 21st. The swell jumps to 10ft from the ESE with an 11-second period, and there’s a slight offshore in the morning. Energy’s strong at 2381. That’s serious size – only for experts. After that, Sunday the 23rd shows a glassy 6ft SW swell with a 15-second period. Another clean window. Monday the 24th is marginal, and Tuesday the 25th fades to 4ft, glassy in the afternoon but small.

So, the call: Thursday the 13th is your best bet – offshore, clean, long-period groundswell, and solid energy. Mark it. Friday the 21st for the experienced crew, but that’s a week out, so treat it with caution. Otherwise, it’s a patchy run with a few clean windows, but not a whole lot of consistency.

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.
