The Lowdown

Alright, folks, Rusty here. Let’s have a look at what’s coming down the line for the next couple of weeks. It’s a bit of a mixed bag, but there are definitely some sessions to keep your eye on.

We’re starting off slow. Honestly, the first several days look pretty average, with a lot of "marginal" reports. The water temperature is sitting at 58°F which is a full 5°F colder than what’s normal for this time of year, so that’s a solid reminder to bring the thickest wetsuit you’ve got. The real standout, the one that’s got my heart racing a bit, is Thursday, August 27th. We’re looking at a solid 7ft swell from the SSW, with a nice 12-second period pushing some real energy (combined swell energy of 1543). But the kicker? The wind is forecast to be glassy in the morning and staying glassy through the afternoon. For Fish Boma, a reef break exposed to the south, that’s about as clean as it gets. This is the pick of the first week, no question.

Before that, Wednesday the 26th looks like it might be a bit of a kite-surfing day. The swell is pumping up to 8ft from the SSW with a very long 16-second period, and the combined energy is huge (3710), but those strong easterly cross-offshore winds will be howling at 22 mph. It’ll be clean, but it’s going to be a battle on a paddle board.

After that Thursday glass-off, the surf starts to drop off through the weekend. By Saturday the 29th, it’s tiny and the wind gets messy, so don’t expect much.

Now, looking into the second week, the forecasts get a little more uncertain, but there’s a promising pulse building for Tuesday, September 1st. The swell is forecast to jump back up to 10ft from the SW with a 14-second period and very strong energy (3344). The wind looks decent in the afternoon with a clean cross-offshore breeze from the east at 12 mph. That’s a big, powerful day that could be firing if the direction locks in. Then, on Wednesday, September 2nd the afternoon could be another beauty, with the swell at 8ft from the SW and glassy conditions. That’s a serious contender if it holds.

The tail end of the forecast gets a bit wild and windy again, with strong onshore winds and lumpy conditions from the 3rd through the 7th, so don’t get your hopes up for that stretch. The swell stays solid, but the quality won’t be there for a good paddle.

So, lock in Thursday the 27th of August and keep an eye on September 1st and 2nd. That’s where the magic is hiding.

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.
