The Lowdown
Righto, let’s have a look at the run ahead. The main show is Fish Boma, a reef break that’s fairly consistent and exposed to the S swell. Water temp is about average for the time of year, nothing unusual there.
We kick off on Wednesday the 22nd with a building SW swell coming in around 7 ft at 12 seconds, but the wind is cross-onshore, so it’s choppy and not really worth paddling out for. The combined energy is already pumping at 1426, but the quality is just not there. Thursday the 23rd is a bit bigger, hitting 10 ft on the afternoon with a shorter 11-second period, but still cross-shore wind and messy.
Now, Friday the 24th morning – this is the standout. A solid 12 ft SSW groundswell with a very long 16-second period, ENE wind is cross-offshore, and the report says clean. The combined energy rockets up to 6184, which is strong. This is proper, powerful groundswell – best for a reef like this, but it’s big, so only for experienced surfers. The wind will have it glassy. Saturday the 25th afternoon looks tidy too, with 8 ft SW swell, a 13-second period, and clean cross-offshore breeze. Combined energy around 2039, solid.
Sunday the 26th afternoon is a beauty – 6 ft SW swell, 11 seconds, and glassy conditions with a light SSE wind. That’s a true gem for the intermediate crowd, clean and inviting. Monday the 27th backslides into cross-onshore chop, so skip it.
Tuesday the 28th gets ugly – 10 ft SSW swell with a 16-second period, but the wind is cross-onshore and moderate, with rain. The energy is 4897, but it’s blown out, poor. Wednesday the 29th is onshore too, messy.
From Thursday the 30th through to the end of the first week, the swell drops, and the wind is mostly cross or cross-onshore, nothing special. A few sessions on the 1st and 2nd of August have clean conditions but small 4 ft to 4 ft SW swell – fun for a longboard or a grovel board, but not a standout.
Then, right at the end of the outlook, on Thursday the 6th of August morning, we get another big pulse: 10 ft SW swell at 14 seconds, glassy, with a light S wind. Combined energy is 3389. That’s a promising one for the experts, but it’s a long way off, so keep an eye on it.
Best on offer: Friday the 24th July morning – big, clean, powerful groundswell for experienced surfers. And Sunday the 26th July afternoon – smaller, glassy, and perfect for the intermediate crew.

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.
