The Lowdown

G’day. Rusty here, looking at the stretch ahead. It’s a bit of a mixed bag, and there’s a real rough patch to start, so don’t get too excited too soon.

The first few days are pretty ordinary. Sunday the 13th has a bit of size – 3.0m – but a period of 9 seconds and a cross-off wind. It’s a bit unruly, the sort of day you’d be wrestling more than riding. We’re looking at a lot of marginal calls through Monday and Tuesday, with waves dropping to 1.3m by Tuesday afternoon. The glassy conditions on Tuesday arvo are a small mercy, but there’s just not a lot of push in it.

We get a bit of a pulse for Wednesday the 16th, with a 14-second period from the SW pushing 3.0m. The energy readings are strong – 3344 – but the wind is a problem, coming onshore, and it’s light rain. It’s not a pretty picture. The energy stays moderate for Thursday and Friday, but the cross-shore chop is a constant battle.

Now, the first real standout in this whole window looks like Saturday the 19th. Saturday morning brings a clean 3.0m from the ESE, with a cross-off breeze and a 9-second period. The energy is solid at 1646. It’s a bit on the bigger side, but the wind is right and it’s clean. This is the kind of morning where the reef at Fish-Boma comes alive. The period is a little short, but the conditions make it work for experienced surfers. If you’ve got the skills, this is your window.

From there it gets messy again. There’s more swell around the 20th – 2.5m – but the onshore flow kills it. Then we run into a proper gap. The 21st, 22nd, and 23rd are all poor. The 22nd has some size but the period drops to 8 seconds, and it’s just bumpy. The 23rd is a write-off, with small, choppy waves. That’s a rough stretch of four days where you’d be better off doing something else.

Then things start to build again. The 24th of September has a bit of a mix. Thursday morning is a mess – 2.5m and a strong cross-shore, lumpy as anything. But Thursday afternoon looks interesting. The swell is still 2.5m, but the period jumps to 14 seconds, and the wind swings cross-off. That’s a big, clean groundswell. The energy reading is strong – 3013. This is a powerful session, but that size and period on a reef means it’s one for experienced surfers only. The 25th backs off a touch to 2.0m with a 13-second period, and the wind is still cross-off. That’s a good, solid day, a bit more manageable.

Then the run fades out. The 26th turns onshore and choppy. The 27th starts with a bit of a pulse – 3.0m – but with a short 8-second period and a cross-shore wind, it’s messy. And then the big one. Monday the 28th of September shows a solid 5.0m on the push, with the energy readings going through the roof at 5349 and 6306. But this is a big, raw, open-ocean pulse, 10-second period, with onshore winds during the morning. That’s a serious amount of water moving, way beyond a fun surf. This is big-wave territory, a day for the chargers only, and even then, the conditions are against it. This is more of a spectator day or a kite-surfing day with that onshore wind and size. For paddling, it’s going to be a washout.

So, to sum it up: the standout mornings to circle are the 19th and the 24th arvo/25th. The rest is mostly a battle. The water temp is 16°, which is a bit colder than usual for this time of year – so suit up properly.

This is Rusty, signing off. Keep your eyes on the 19th and 24th.

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.
