The Lowdown

Alright folks, Rusty here. Let’s get into it.

We’ve only got one spot on the menu for the next 16 days, and that’s Fish Boma. It’s a reef setup, exposed to the south swell, so when it’s on, it’s on. There’s a bit of a slow start, and the first weekend is looking pretty average. Saturday the 5th is a write-off – small, messy cross-shore chop, and the water’s sitting at 61°, which is a bit colder than usual for this time of year. Nothing to get excited about there.

The first real glimmer of hope comes Sunday the 6th. We’ve got a solid 8ft to 10ft SSW groundswell rolling in, with a very long period of 17 to 19 seconds. The wind is clean off the land from the east, so the surface should be smooth. This is heavy, powerful surf – over 8ft is expert-only territory, and with that period, it’ll be sucking up on the reef. The combined energy is massive (5113 to 5772), so this is proper, serious wave energy. If you’re good enough, this is your window.

Monday the 7th morning is the standout. The swell drops to a still-chunky 7ft from the SSW, period a long 14 seconds, and the wind is barely a whisper from the ENE, making for clean, glassy conditions. The combined energy is still strong at 2826. This is the cleanest, most manageable day of the run for experienced surfers.

After that, it gets a bit mixed. Tuesday the 8th is smaller and weaker, and by Wednesday the 9th, the swell collapses and the wind turns onshore, making for poor surf. A gap of poor conditions follows.

Thursday the 10th morning brings a nice surprise: glassy conditions with a 7ft SW groundswell, period 16 seconds. The energy is solid (1953), and the glassy surface is a major plus. It’s a quick window, as the wind shifts onshore by the afternoon.

We get another big pulse on Saturday the 12th, with 10ft from the ESE, but the period is short (9 seconds), so it’ll be a bit lumpy and less organised. The offshore wind keeps it clean, but it’s more of a powerful, wind-swept affair.

The next real gem is Tuesday the 15th afternoon. A 8ft SW swell, 12-second period, with glassy, no-wind conditions. The combined energy is 2310, and the surface will be like a mirror. For a more experienced crew, this is a treat.

And then, the big one for the long-range crew: Saturday the 19th morning. The forecast shows a 13ft S swell, period 12 seconds, with glassy conditions. The energy reading is a staggering 4975. This is huge, powerful, and pristine. It’s over 8ft, so experts only, but if you can handle it, this could be the session of the whole forecast. Keep an eye on it, but it’s two weeks out, so things can change.

Overall, the best windows are Monday the 7th morning for the cleanest, most powerful yet manageable surf, and Tuesday the 15th afternoon for a glassy, mid-sized session. The 19th is a potential monster, but it’s a long way off.

Crowds at Fish Boma can happen, so you’ll want to be early for those clean windows.

Stay salty,
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.
