The Lowdown

Alright, Rusty here. Let's talk about what's shaping up at Fish Boma. It's a reef break, breaks pretty consistently, and it's wide open to any swell coming from the south, which is its best direction. The water is running about 59°, which is a touch colder than it should be this time of year, so you'll need a good wetsuit.

The month kicks off with a pretty weak start. Monday, August 31st, has some 5-foot swell from the southwest, but don't get your hopes up; the conditions are marginal. The combined energy reading is only 625, so it's not got much punch.

Things ramp up on Tuesday, September 1st. A bigger SW groundswell moves in, hitting 8 feet in the morning with a 12-second period, and then building to 8 feet in the afternoon with 13 seconds. The combined energy jumps to 2414 by the afternoon. But the wind is onshore, so the surface is going to be a bit bumpy.

The real standout, and I mean the one to circle on the calendar, is Wednesday morning, September 2nd. The swell is a solid 10 feet from the southwest, with a deep 13-second period, and the combined swell energy is a powerful 2982. What makes it special is the wind – it's absolutely glassy, not a breath of air. That's pure, clean power on a reef, but anything over 8 feet is for experts only.

After that, things get messy. Thursday, September 3rd, has a jumbled 13-foot S swell in the afternoon, but the period is short at 9 seconds, and a fresh onshore breeze is going to make it lumpy and tough. The energy is still high at 2924, but the quality is shot. This setup looks more interesting for kite surfing than a paddle session.

The next week is a mixed bag of cross-shore winds and fading, short-period swells. Saturday, September 5th, has a weak 7-foot ESE swell, but it's choppy and not worth the drive.

Then Sunday, September 6th, throws in a very long-period SSW groundswell at 17 seconds. It starts the morning at 8 feet (combined energy of 3932) and drops to 7 feet in the afternoon. That kind of period will wrap nicely into the reef. The wind turns cross-offshore in the afternoon, cleaning it right up. It's a good, powerful option, though that very long period can make it a bit walled-up.

The next real gem is Tuesday morning, September 8th. You've got a clean 7-foot E swell, but the wind is offshore from the NNE at 15 mph. The combined energy is moderate at 1000, but that offshore wind will groom it perfectly for the reef. Another one for the experienced crew.

After that, the swell really drops off. Wednesday, September 9th, has a small 4-foot clean wave, but the energy is low. The rest of the forecast into mid-September is small, weak, and mostly blown out by cross or onshore winds. Not much to write home about.

So here's the call: if you want the best, you get up early on Wednesday, September 2nd. That 10-foot glassy groundswell is the one. For a slightly smaller, cleaner option with a good offshore wind, look at Tuesday morning, September 8th.

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.
