The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Fish Boma over the next couple of weeks.
The overall pattern is a bit of a slow burner. We've got a heap of energy in the water, but for the first week or so, the wind is just going to mess it up. You'll see solid swell on the charts, but the conditions are going to be a write-off for a good few days. The first real chance of anything decent doesn't roll around until we get a bit further into the period.
For the opening days, from Sunday the 9th right through to Tuesday the 11th, it’s a write-off. We're looking at strong onshore and cross-shore winds with swell heights between 6.9 ft and 11.5 ft. The combined energy is strong to very strong, peaking at 6292 on Sunday afternoon, but it's all for nothing with that wind. It's going to be a messy, lumpy, choppy mess. Not worth paddling out.
Things start to look up on Wednesday morning, the 12th. The wind swings around to a light cross-offshore breeze, and while the swell drops to 4.6 ft, the period jumps to a very long 20 seconds from the SSW. The energy is still moderate-strong (2247). This is clean, but the tide might be a bit tricky. It’s one for the experienced crew only, as that long period groundswell will be a bit shifty on the reef.
The standout window is from Thursday the 13th through to the morning of Friday the 14th. This is the pick of the forecast. Thursday morning is the absolute jewel. We’ve got a clean 5.6 ft swell from the SSW with a long 19-second period, combined with a true offshore wind from the NNE. The energy is massive (4416), and the text says it’s excellent for experienced surfers. Thursday afternoon holds clean with a 7.2 ft SW swell (17 seconds), and Friday morning follows up with another clean session, offshore wind, and a 4.6 ft SW swell (16 seconds). The water temp is about average for this time of year.
Friday afternoon on the 14th is also a gem – glassy conditions with a 3.9 ft SW swell and a 15-second period. The energy is moderate (930), but that glassy surface will make it feel like butter. A top session for a log or a mid-length. Just be aware that crowds are *sometimes* a thing here, so get on it early.
After that, it all gets a bit small and onshore again for the weekend of the 15th and 16th. Swell drops below 3.6 ft with light cross-on breezes, not really worth the hassle. Monday the 17th sees the swell bump back up to 5.2-6.9 ft with long periods, but the wind is a light cross-on again, so it’s marginal.
Tuesday the 18th offers another great session. Morning glass and a clean 5.6 ft SW swell (13 seconds). The energy is moderate (1186). Afternoon stays glassy with a 4.6 ft swell. That morning window looks excellent.
From Wednesday the 19th onward, the wind goes back onshore, and while there's still plenty of swell (7.2 ft to 9.8 ft) with moderate to strong energy (1725 on Wednesday afternoon), it's going to be choppy and messy. The swell period also drops significantly on Wednesday to a short 7 seconds, so it’ll be weak and lumpy. The final real chance to score comes on Friday the 21st of August. The morning session shows a clean 7.2 ft SSW swell with a moderate 11-second period and a cross-offshore breeze. It's still a bit big, but the conditions are clean.

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.
