The Lowdown
G'day, Rusty here. Let's size up the next couple of weeks.
We start on Thursday, August 27th with a clean window at Fish Boma (reef). The water is 60°, which is running a bit cooler than usual for this time of year, so plan accordingly. Thursday morning is the standout. A solid 7ft SSW groundswell with a 12-second period, light cross-off wind from the ENE, and moderate wave energy (1645). It's excellent, clean surf for experienced surfers. Crowds are possible, so get in early.
From Thursday afternoon through to August 31st, it's a mixed bag of onshore winds and marginal surf. Swell runs from 3ft to 6ft, but the wind is messy, and the energy drops into the moderate to weak range (575 to 1169). Not worth paddling out.
After a few days of nothing special, we get a big pulse on Wednesday, September 2nd. The swell jumps to 13ft from the SW with a 14-second period, and the energy is strong at 6175. This is a massive groundswell—only for experts. The wind is light and onshore, so it'll be lumpy. If you're into kite surfing, the combo of big swell and onshore wind looks more interesting than paddling.
The next few days, September 3rd and 4th, see the swell hold at 12ft to 16ft, but the wind gets stronger and onshore with rain. Energy is very strong (3644 to 5197), but the conditions are poor. Total power zone.
Things clean up on Saturday, September 5th. The swell drops to 8ft from the SSW, with a light cross-shore wind from the SE. Energy is strong at 1930, but conditions are still marginal.
Then we hit the best run of the whole forecast. Sunday, September 6th and Monday, September 7th are looking magic. Sunday morning has 6ft of ESE swell, a light cross-off wind from the ENE, and strong energy (1747). Monday morning is even better, with a light offshore from the NNE and the same 6ft ESE swell. Clean, fun-sized waves. Crowds are possible, but it'll be worth it.
After that, it fades. From Tuesday, September 8th through to Wednesday, September 9th, the swell drops to 4ft to 5ft from the ESE with a short period of 8 to 9 seconds. The wind is cross-onshore, and the energy is weak (278 to 455). Poor conditions.
Thursday, September 10th is a lull with a tiny 1ft swell from the SW, but a very long 19-second period. Energy is weak at 254. Not much on.
Finally, on Friday, September 11th, we get one more pulse: a 13ft SW groundswell with a 13-second period, and a cross-shore wind from the ESE. Energy is strong at 4622, but the conditions are marginal with a slight cross-chop. Another big one for experts only.
So, make your plans for Thursday, August 27th (morning) and the weekend of September 6th-7th. The rest is either a bust or for the hardcore.
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.
