The Lowdown
Alright, let’s get into it. The fishin’s good at Fish Boma, and it’s a reef break that’s exposed to the south swell. The water’s sitting at 63°F right now, which is bang on average for the time of year, so no surprises there.
We’ve got a bit of a slow start. Monday the 27th is a write-off, with a messy cross-shore wind and a 7ft SW swell that’s just not cooperating. The combined energy is moderate (1738), but the wind’s killing it. Forget it. Tuesday the 28th is a step up, with cross-offshore winds and a 8ft SSW swell, period 15 seconds – that’s proper groundswell. The energy’s moderate to strong (2740), and the waves will be clean. It’s a decent option for the intermediate crew.
But the real standout? Thursday morning, July 30th. Glassy. Flat calm. A 5ft SW swell with a 13-second period, energy at 1210 (moderate), and the wind is dead still. That’s as clean as it gets. The waves will be shaped and smooth, perfect for a reef break like this. Definitely the best on offer in the first week.
The next big highlight is Tuesday morning, August 4th. This one’s for the experts only. An 12ft WSW swell, period 12 seconds, and the energy is strong (6122). It’s glassy again, with zero wind. That’s a serious, powerful groundswell hitting the reef. If you’ve got the skill and the nerve, this is the day. Not for beginners – that’s way over 8ft.
August 8th is another solid call. Saturday morning, glassy, 8ft SSW swell at 14 seconds, energy at 3049 (strong). The winds are light, and the waves will be clean and powerful. Good for experienced surfers.
The second week has a few more promising days, but the standout is that August 4th window. The 6th of August also has a glassy morning with an 8ft SW swell, but it’s not quite as big as the 4th. The 8th and 10th also offer clean conditions, but the energy’s a bit lower.
Bottom line: if you’re looking for the best, pencil in Thursday the 30th of July for a fun, glassy session, and Tuesday the 4th of August if you’re chasing something big and powerful. Crowds are possible at Fish Boma, so get there early.

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.
