The Lowdown
Alright, Rusty here. Let’s get into it.
We’ve got a solid window of surf ahead at Fish Boma, a reef set-up that’s exposed to the south-west groundswell. The water is sitting at 59° right now, which is a good 4° colder than usual for this time of year – so you’re gonna want a thicker steamer if you’re paddling out.
The first real call is Friday morning, the 14th. Swell is 5 ft from the SW, with a long period of 16 seconds. That’s proper groundswell energy, and the combined energy is pumping at 1317. Wind is light and offshore from the NNE, so it’ll be glassy clean. This is a reef break, so that long period will wrap in nicely. It’s an intermediate spot, but with that size and power, it’s one for experienced surfers. Crowds are possible.
Friday afternoon the wind switches to a cross-onshore from the SW and the quality drops right off. Not worth it.
Saturday the 15th is a write-off – small, cross-shore wind, marginal conditions both morning and afternoon. Sunday the 16th morning is still messy, but Sunday afternoon? Wind drops to glassy, 4 ft SW swell, period 12 seconds. The energy is low (483), but it’ll be clean and fun for a cruisy session on a longboard.
Now here’s the standout. Monday morning, the 17th. Swell jumps to 7 ft from the SW, period 13 seconds. Combined energy is 1712. Wind is glassy from the SSE. That’s clean, powerful surf for the experienced crew. This is the best on offer in the first week.
Tuesday the 18th holds solid 7 ft swell but the wind is cross-shore, so it’s a bit bumpy. Wednesday the 19th has similar size but cross-onshore winds – not great.
Thursday the 20th morning is clean again – glassy SSW wind, 6 ft SW swell, 12-second period. Good energy (803) and clean. A solid session.
Then we hit a flat spell. Friday the 21st and Saturday the 22nd morning are poor. But Saturday the 22nd afternoon? Watch out. A big pulse arrives: 16 ft from the SSW, period 16 seconds. Combined energy is 13146. That’s huge. Cross-on wind though, so it’s gonna be a bumpy, challenging beast. Only for experts, and even then, it’s a heavy reef.
Sunday the 23rd still has big 13 ft SSW swell, 15-second period, with cross-shore wind. Slightly cleaner but still massive. The energy is 7973. This is not for the faint-hearted.
Monday the 24th drops to 10 ft, still big, cross-shore wind. Still a big-wave day. The energy is still well into the thousands (3347). This run of big swell continues through to Wednesday the 28th, with sizes between 8 ft and 10 ft, but the wind is mostly cross or cross-on, so it’s never truly clean.
The standout in the second week? Saturday the 22nd afternoon and Sunday the 23rd are for the big-wave crew only. The energy is enormous, but the wind is a letdown. If you’re an expert and you don’t mind some chop, there’s power to be had.
Thursday the 27th morning has an 8 ft SW swell with a 15-second period, but the wind is a cross-onshore breeze, so it’s choppy. Not the best.
We finish out the 16 days on a small note. Friday the 28th and Saturday the 29th are small, around 5 ft to 5 ft, with cross-shore winds. Marginal.
Overall, the best window is Monday morning the 17th for clean, powerful surf. The big pulses on the 22nd and 23rd are for experts only, in messy conditions.
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.
