The Lowdown
Alright, this is Rusty. Let's take a look at what we've got coming down the line.
Alright, patchy start, but there's some serious meat in the second week here. We've got a solid window of solid groundswell, but you've got to pick your moments with the wind. The best call of the whole 16-day forecast is a big, clean swell that's going to fire, but we'll get to that.
First up, Fish Boma (reef) . Water temp is sitting at about 63°, which is pretty average for the time of year—nothing unusual there. The first real sniff of something good is on Thursday the 31st. Dawn patrol on the 31st looks tidy: 6ft of SSW groundswell at a long 13 seconds with a light cross-off breeze. It's a good, clean wave, but it's for the experienced lot. That afternoon the swell jumps up to 8ft, but the period crashes to 7 seconds and the wind picks up—messy, short period chop. Not worth the paddle.
Saturday the 1st of August is a standout. We’ve got 8ft of ESE swell, a 9-second period, and the wind is completely glassed out in the morning. That's a beautiful window. Clean, lined-up waves with moderate energy (1076). The crowd can be around, but for conditions like that, it's worth sharing. The glassy conditions are a huge plus.
Sunday the 2nd is another stunner. 6ft of ESE swell, period holding at 9 seconds, and it's dead calm again in the morning—total glass. The water will be like a mirror. Wave energy is solidly moderate (873). That's a beautiful, cruisy day for a paddle.
We then hit a bit of a lull early in the week. Monday and Tuesday have smaller swell, though some glassy conditions on Tuesday the 4th morning (4ft SW, 11 secs, 553 energy). Worth a look for the older crew on logs.
Now, Wednesday the 5th of August afternoon – this is the one I'm talking about. It's a full-on standout. The swell hits 8ft from the southwest, period is a thumping 14 seconds, and the wind drops to a flat calm. No wind at all. The wave energy is massive (2574). This is proper groundswell for the reef. It will be big and powerful—expert territory only. The sets will be clean, heavy, and well-spaced.
After that, it gets big and gnarly. Thursday the 6th through to Sunday the 9th sees consistent SW swell from 8ft up to a solid 12ft, but the wind starts to foul things up. It goes cross-on and onshore, becoming choppy and lumpy. On Saturday the 8th, with 10ft and a fresh 22 mph cross-on, and rain, it's looking more like a kite-surfing zone than a paddle session. A real shame because the swell is pumping.
Monday the 10th of August is another very promising window. We get 12ft of E swell with a period of 9 seconds and glassy conditions in the morning. Massive energy (4392) and clean. That's another bomb for experts only. The long period groundswell on the 12th and 13th is also worth watching, with the 13th offering a clean 8ft SW swell and light offshore winds.
So, bottom line: The calendar is packed with heavy swell. Your absolute best bets are the glassy mornings of August 1st, 2nd, and that massive, clean afternoon on August 5th. The big stuff after that is for the brave and skilled only.
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.
