The Lowdown

Alright folks, Rusty here. Let’s have a look at the next couple of weeks at Fish Boma. This is a reef setup, exposed to the south swell, and it’s going to be a bit of a mixed bag, but there are some real windows of pure magic if you're keen.

The first few days are on the cards, but the conditions are a bit all over the place. We’ve got some solid swell building, but the wind is often on it or cross-on, which musses it up. The real standout, the one you want to circle, is Thursday morning, the 27th of August. We’ve got a clean 6ft SSW swell rolling in at a long 12 seconds, and the wind is absolutely glassy. That’s as good as it gets. The water temp is sitting about average for the time of year, so no nasty surprises there. The energy is moderate to strong (1469), so there’s some push behind it. This is a window for experienced surfers – it’s not giant, but it’s got the juice.

Thursday afternoon looks even better for the glassy conditions, with a slightly smaller 5ft, but still clean and lined up. That’s a sweet afternoon session.

After that, the weekend gets a bit lumpy. Friday the 28th still has some clean waves in the morning, but the swell drops off to 5ft. By Saturday the 29th, it’s small and messy, honestly not worth paddling out for.

We then hit a bit of a lull, with a few days of poor surf and onshore winds through the end of August and into the start of September. A solid 4-5 day gap of no real recommendations.

The next real highlight pops up on Wednesday morning, the 2nd of September. The wind goes light and offshore out of the northwest, cleaning up a 7ft SW swell with a 12-second period. The energy is there (1296), and it’s going to be cranking. This one is for the experienced crew again – a proper reef swell with good shape. Keep in mind, with a longer period like that, it might throw some bigger sets and be a bit too much for the beginners.

Looking further out, the second week is a bit of a promise. The long-range stuff on Sunday, the 6th of September, is the biggest call of the whole forecast. We’re seeing a 10ft SW swell (13 seconds) with light onshore winds in the afternoon and a massive energy reading of 6464. That’s a serious, powerful swell. The wind is a bit of a question mark, but if it cleans up, that’s a big, heavy day for the experts only. Over 8ft, it’s strictly for the brave.

The swell then drops back down through the 7th and 8th, with the 8th of September morning looking clean and small again at 4ft with offshore winds.

So, to sum it up: Thursday 27th August is your best bet for a glassy, quality session. Wednesday 2nd September is a close second for a punchy, clean swell. The big swell on the 6th is a monster if you’re an expert, but it’s a long-range call. Crowds are always a possibility here, so get there early, especially on the good days.

Stay safe out there, and remember, the ocean doesn't care about your plans.

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.
