The Lowdown
Alright, let’s talk surf. We’ve got one spot on the radar for the next couple weeks – Fish Boma. This is a reef break that’s exposed to the south and picks up swell pretty well. Water temp’s sitting around 64°F, which is bang on average for this time of year, so no surprises there.
The first few days are a bit of a mixed bag. Monday the 20th starts with a weak 6ft SW swell, period around 11 seconds, but the wind is light cross and the conditions are just marginal. Not worth getting too excited about. Tuesday the 21st morning looks better – glassy conditions with 7ft of long-period groundswell from the SSW, 14 seconds. That’s clean, but the swell is still manageable for experienced intermediates. Tuesday afternoon turns cross-on and bumpy, so morning is the call.
Wednesday the 22nd is pretty average – cross-on wind, 7ft SW, not great. Thursday the 23rd is even worse with a choppy 10ft and short period. Then Friday the 24th – that’s the standout. Morning sees a solid 12ft SSW swell with a very long 15-second period, clean cross-off wind from the east. That’s big, powerful, and only for experts. The reef will handle that long period beautifully, and the energy is pumping – combined energy of 5871. This is the best session on offer, no question. Saturday the 25th morning still has a nice 8ft SSW groundswell with clean cross-off wind, great for experienced surfers but a step down from Friday.
Sunday the 26th morning is clean again, 7ft SW, but by afternoon it goes glassy with 7ft and 12 seconds – that’s a lovely session for anyone who can handle the reef. Then things get a bit messy. Monday the 27th has very strong north winds, 40 km/h (25 mph) in the morning, making the 5ft swell ugly despite being clean – the wind is just too strong. Tuesday the 28th through Wednesday the 29th are a write-off with strong cross-on winds and big messy swell, 12ft to 13ft, poor conditions. Thursday the 30th still has a cross-chop but the swell drops a bit.
Then Friday the 31st rolls around – another standout. Afternoon session has a 12ft SW swell with 12-second period, clean cross-off wind from the east, combined energy 3241. That’s an excellent expert wave, though it’s a week and a half out, so hold your horses. Saturday the 1st of August has a bit of cross-chop but still 12ft SSW groundswell – not as clean. Sunday the 2nd and Monday the 3rd see a drop in size and quality, with onshore winds returning. By Tuesday the 4th, the swell is small and choppy.
Overall, the best bets are Friday July 24 morning and Friday July 31 afternoon. The first is more reliable, the second is promising but a bit further out. Expect crowds at Fish Boma sometimes, especially on the good days – it’s a known spot.

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.
