The Lowdown

Alright, folks, Rusty here. Let’s have a look at what’s cooking for Fish Boma.

We’re starting a little slow, nothing to write home about for the first couple of days. Conditions are a bit messy, so don’t rush out just yet. The good stuff starts rolling in from Thursday, 11 September, and there are some truly beautiful windows.

Thursday, 10 September is a mixed bag. The morning has a 1.3m SSW swell with a 16-second period, but it’s cross-onshore. The afternoon bumps up to 2.2m from the SW at 15 seconds, but the wind’s onshore and the combined energy is solid (2207). Not perfect, but there's power.

Friday, 11 September morning is the first real highlight. We’ve got a 1.9m SW swell with a 13-second period, light cross-offshore wind from the East, and a combined energy of 1228. It’s clean and punchy. The wave comment says it’s excellent for experienced surfers – at 1.9m, it’s a bit much for beginners. The afternoon drops to 1.4m but stays clean.

Saturday, 12 September morning is an absolute gem. The wind is glassy, dead calm, with a 1.2m SW swell at 15 seconds. Combined energy is 1349, and the surface is like a mirror. That’s the session you wait for. The water is 59°, which is 4° colder than normal for this time of year – that’s a pretty big anomaly, so bring the thick rubber.

Sunday, 13 September morning brings a bigger 2.1m SSW swell at 15 seconds with a cross-shore breeze. The combined energy jumps to 3662. It’s getting solid. The afternoon gets a bit chop with the wind picking up to 9 mph.

Monday, 14 September morning is another good call. A 2.0m SE swell at 9 seconds with a light offshore breeze from the NNE. Combined energy is 1118 and it’s clean. The short period means it’ll be a bit fat, but offshore wind fixes a lot.

After a lull, we hit a massive pulse on Wednesday, 16 September. The morning has a huge 3.5m SW swell at 18 seconds with 7070 energy. The afternoon pumps up to 4.0m at 17 seconds and 8578 energy. This is expert-only, big-wave territory. The winds are onshore or cross-onshore, so it’ll be lumpy, but for the chargers, that’s the ticket.

Thursday, 17 September stays big at 3.5m, but the wind is howling at 12 mph from the WSW, making it choppy and messy for a paddle. This setup looks a lot more interesting for kite surfing than paddle surfing.

Saturday, 19 September morning cleans up again. A 3.0m ESE swell at 9 seconds with cross-offshore wind from the East. Combined energy is 3195, and it’s clean. Again, a short period, so expect some close-outs, but it’s big and clean.

The final week has another solid pulse on Tuesday, 22 September. The morning shows a 3.5m SW swell at 13 seconds with a cross-offshore East wind at 15 mph. Combined energy is 4237. The afternoon has the same size with a fresh 18 mph wind.

The standout call – no doubt about it – is Saturday, 12 September morning at Fish Boma. That glassy, 1.2m SSW swell with a 15-second period is pure magic. The water’s cold for the season, but the conditions are worth every shiver.

For the big-wave hunters, Wednesday, 16 September is the one to circle. That 4.0m monster at 18 seconds is a beast, even if the wind isn’t perfect.

There’s a lot of surf across this period, but the quality jumps around. Pick your moments and you’ll score.

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.
