The Lowdown
Alright, listen up people. Rusty here with the lowdown on Fish Boma. It’s a reef break that fires with some consistency. Water temp is about 59°F, which is a couple of degrees colder than usual, so don't be a hero in shorts.
The surf kicks off on Sunday the 23rd with a 7ft SW swell showing up, carrying a moderate energy. Light offshore wind in the morning is a plus, but the report says the tide might mess with it. Period is 11 seconds, a proper groundswell for the reef.
Come Monday the 24th, the swell drops to about 5ft and the vibe goes flat. Tuesday the 25th gets better, with 8ft to 8ft SW swell. The morning is clean with offshore wind, but the afternoon gets some cross-onshore bumps.
Wednesday the 26th is a wipeout. East wind kicks up to 15-22 mph, ruining the 5ft to 5ft swell.
Now for the good stuff. Thursday the 27th is the one to circle in the first week. We’ve got a 6ft SW swell in the morning with glassy conditions—dead calm. The afternoon stays glassy with a 5ft S swell. This is the cleanest, most lined-up reef surf you'll see all week. The report calls it “excellent.”
Friday the 28th is weak, with 5ft to 4ft swell and a light cross-shore. Not worth the paddle.
Saturday the 29th is a dud. Strong winds, fading swell. Skip it.
Into the second week, the big stuff arrives. Sunday the 30th is for the fearless. An 12ft WSW swell rolls in with clean offshore wind. That’s expert territory. The afternoon sees 13ft and a cross-shore wind, making it a bumpy mess of power. Energy is strong.
Monday the 31st stays around 10ft with glassy conditions in the morning. Solid. Tuesday the 1st holds at 8ft to 8ft with a glassy start.
Wednesday the 2nd and Thursday the 3rd go berserk. The swell keeps building and the onshore wind picks up. By Thursday afternoon, the data shows a 26ft SW swell with insane energy readings—over 66000. That is not for paddling. That is for jet skis or kite boards if you're crazy enough. Friday the 4th is the same story, with 23ft swell.
If you’re an expert, Saturday the 5th of September is the best day of the whole forecast. The swell drops to a still-enormous 15ft from the SSW, but the wind is glassy. The report says “exceptional surf conditions for expert surfers.” It doesn’t get any better for the big-wave crew.
Sunday the 6th is still 16ft, but the wind gets onshore, so the quality goes down. Monday the 7th is the finale with 12ft swell and a light cross-onshore breeze.
Bottom line: first week, save your energy for Thursday the 27th for the cleanest waves. Second week, if you’ve got the guts for it, Saturday the 5th of September is your all-time session. Everything else is either too small, too windy, or too damn big.
Watch the reef.
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.
