The Lowdown

Alright, this is Rusty, and I’m looking at what’s on the cards for Fish Boma over the next couple of weeks.

Right off the bat, the water is sitting at 58°F – that’s nearly 5°F colder than what you’d expect for this time of year, so it’s a proper chilly one. Make sure you’ve got a decent wetsuit if you’re heading out.

The first real chance of anything decent doesn’t show up until Friday morning, the 21st of August. The swell is a solid 7 ft, coming from the southwest, with a period of 12 seconds. The wind is clean and cross-off from the east, which is a good sign. The combined energy is moderate at 1256, so there’s some push behind it. This is one for the more experienced crew.

Things are a bit average over the weekend and into the start of the following week. The wind is a bit messy, mostly cross-onshore, and the swell is up and down. It’s not the kind of session you’d plan a trip around.

Now, keep your eyes on Wednesday the 26th of August. That morning, we’ve got a clean 6 ft of southwest groundswell, with a 14-second period and a light offshore wind from the north. It’s a proper setup for the reef. The energy is solid at 1627. By the afternoon, it goes glassy, with the same 6 ft swell. This is a standout, clean and well-shaped, but it’s one for the intermediate to advanced surfer.

Then, and this is the big one for the longer range, look at Saturday the 29th of August. The morning is looking exceptional. A massive 15 ft west-southwest swell, with a 13-second period, and a clean east cross-off wind. The combined energy is a massive 10350, which is very strong. This is a heavy, powerful swell. It’s only for expert surfers, and you’ll want to be well across the tides and conditions. This is a standout, but it’s a long way out, so keep an eye on it.

After that, the swell settles back down, but there are some nice glassy windows in the first couple of days of September. The 31st of August afternoon looks tidy with a 6 ft, 15-second glassy swell, and the 1st of September afternoon also has a glassy, clean 6 ft swell. Good for a solid session if you’re around.

Overall, there’s a bit of a wait for the first good one, but the 26th and the 29th are the ones to mark on the calendar.

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.
