The Lowdown
G'day, I'm Rusty. Let's have a look at what's on the cards for Fish Boma over the next couple of weeks.
Alright, we've got a bit of a mixed bag coming our way, but there are some serious standouts to get excited about. The opening days are a bit of a write-off, so be patient. The real magic happens mid-period and into the second week.
The first solid opportunity rolls in on Sunday, September 6th. The afternoon sees a solid 10ft SSW groundswell, but a 19 mph east wind makes it cross-off. The wave energy is pumping, a strong 5827, but the wind's got some sting in it, so it won't be perfect. The water's sitting at 60°, which is a noticeable 3° colder than normal for this time of year, so you'll want a decent spring suit.
Monday, September 7th morning is where it starts to clean up. The swell drops a touch to 7ft from the SSW, still with a nice 14-second period, but the wind drops right off to just 3 mph from the east, keeping it cross-off and clean. The energy is still strong at 2755. This is excellent for experienced surfers.
Tuesday, September 8th morning is a real gem. We get a glassy 5ft easterly swell. The period is short at 9 seconds, but the glassy conditions and slight air make for a very clean, user-friendly morning. The energy is moderate at 714.
Then things get a bit messy through Wednesday and Thursday morning, with onshore winds and smaller, choppier surf. Thursday, September 10th afternoon is another absolute standout. The wind goes glassy, and a 10ft SW swell with a very long 16-second period rolls in. The energy is huge at 4034. This is going to be a heavy, clean groundswell, excellent for experienced surfers. This is a top pick.
The weekend of the 12th and 13th has some solid size but windy conditions. Saturday, September 12th sees 10-11ft easterly windswell, but it's short period (8 seconds) and pushed by fresh easterly winds. It'll be lumpy, but cross-off winds will keep the surface clean. This setup might actually be more interesting for kite surfing than paddle surfing, given the short period and strong wind. The real highlight returns on Sunday, September 13th morning with a 6ft SSW groundswell (14s) and a perfect offshore breeze from the NNE at 9 mph. The energy is strong at 2498, and the conditions will be clean. This is another excellent window for experienced surfers.
Looking further out, Tuesday, September 15th is a cracker. The morning is glassy with an 8ft SW groundswell (14s) and strong energy (2463). The afternoon sees a clean 8ft SW swell with light cross-off winds. Two excellent sessions in one day for experienced crew.
Now, a big one to circle on the calendar: Thursday, September 17th morning. This is the biggest swell of the period at 15ft from the SE, with a short 10-second period. The energy is enormous, a 9428. The wind is a fresh cross-shore at 19 mph, so it'll be lumpy, but there is serious power here. This is only for experts, no question. The afternoon drops to 13ft but stays cross-off and clean.
Friday, September 18th is a winner. The morning delivers a clean 10ft SE swell (10s) with light cross-off winds and strong energy (2146). The afternoon stays clean with an 8ft SE swell. Two more excellent sessions for experienced surfers.
The final standout is Saturday, September 19th afternoon. The wind goes glassy, and a 5ft SW groundswell with a very long 16-second period comes through. The energy is 1576. It's clean and perfect for a relaxed session.
Monday, September 21st afternoon is a nice way to end the run: glassy conditions with a 6ft SW groundswell (13s) and excellent conditions.
So, to boil it down, the absolute best bets are the glassy sessions on Thursday, September 10th afternoon and the offshore/glassy windows on Tuesday, September 15th and Friday, September 18th. The massive swell on the 17th is for the brave only. Get out there.
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.

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.
