The Lowdown

Alright, Rusty here, let’s look at what’s brewing.

Only one break to talk about: Fish Boma. It’s a reef, open to south swell, and it loves it from the south. Water temp is about normal for the season.

Starting off, Wednesday the 9th morning, it’s small – 2ft from the southwest, 14-second period, light west wind. Energy’s moderate (404), but the report says it’s marginal. Afternoon glass-off cleans it up: 3ft, same direction, glassy. Tiny but clean.

Thursday the 10th, swell picks up. Morning is 5ft from the SW, 16-second period, but cross-on wind from the WSW at 6 mph makes it bumpy. Afternoon gets to 7ft, same direction, but onshore SSW wind at 6 mph. Messy.

Friday the 11th morning is the first real gem. Glassy, north-northeast wind at 3 mph, 6ft SW, 13-second period. Energy is moderate (974). “Very good surf conditions” – that’s the early pick. Clean, fun.

Saturday the 12th is average, with cross-on wind. Sunday the 13th gets bigger: 7ft SW in the morning, but onshore. Not great.

Monday the 14th afternoon is interesting. Swell shifts to the ESE, 6ft, glassy, but only 9-second period. Short period means weaker waves, but glassy is glassy.

Tuesday the 15th afternoon is the big standout. Swell is 5ft from the SSW, but the period is 21 seconds – that’s a very long groundswell. Energy is strong (2748). Wind is east at 6 mph, cross-off, clean. “Excellent surf conditions for experienced surfers.” Long lines, heaps of power, but long lulls. Crowds possible. Not for beginners.

Wednesday the 16th is blown out – strong SSW winds at 18 mph, 8ft SW, poor. That’s kite-surf stuff.

Friday the 18th morning is another good one: 6ft SW, 15-second period, light north-east cross-off wind, clean. “Excellent” conditions.

Saturday the 19th is bigger, 8ft SW, but onshore. Not ideal.

Sunday the 20th is a write-off – strong WSW winds, 10ft SW, choppy.

Monday the 21st is the biggest of the run: 15ft from the SSW, 16-second period, energy massive (9287). Light onshore wind. Experts only – that’s heavy, dangerous surf. Afternoon cross-shore with 13ft.

Tuesday the 22nd morning drops to 10ft, cross-off east wind, clean, “excellent.” Still big, but more manageable.

The last days of September drop off. Thursday the 24th morning: 8ft from the east, 8-second period, glassy, “excellent.” Short period means weaker, but glassy and 8ft is still fun.

Best calls: Friday the 11th morning, Tuesday the 15th afternoon (that 21-second groundswell is a rare treat), and Friday the 18th morning. For the big-wave crew, Monday the 21st is the one.

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.
