Table - best surf conditions forecast for Fish Boma over the next 16 days.
Hey everyone, Rusty here. We’ve got a solid run of surf ahead at Fish Boma, though it’s a bit of a mixed bag with plenty of action for those who know what they’re doing. The water is sitting at 62°, which is pretty much what you’d expect for this time of year, nothing unusual there.
We kick off Saturday, July 11, with a decent pulse. Morning sees a 8ft SSW swell, and that’s a big one – over 8ft, so this is for experienced surfers only. The period is 12 seconds, a proper groundswell, and with light cross-offshore winds from the east, it’s going to be clean. The energy is pumping, hitting over 2000 (2047), but the crowds can turn up here sometimes. By afternoon, the wind swings cross-shore and it gets a bit messy, so don't sleep in.
Sunday morning, July 12, is a solid option too. Swell drops to a still-chunky 5ft from the SSW, period down to 11 seconds, but the wind is light cross-off again. Energy is moderate (756), and it’s a good shout for intermediates if you want cleaner waves. Afternoon gets cross-shore again, so morning is the call.
Monday, July 13, is a real treat. Glassy conditions in the morning, wind is almost non-existent from the west. Swell is 4ft from the SSW, period 10 seconds – nothing huge, but clean and workable. Energy is moderate (577). Perfect for a long session without the crowd pressure.
Tuesday, July 14, stays glassy all day with a shift to smaller ESE swell around 4ft, period short at 8 seconds. Energy drops to 347. It’s fun, but not pumping.
Then we hit a bit of a lull until Thursday, July 16, when a big SW groundswell rolls in – 8ft with a 14-second period, but the wind is cross-on and howling by afternoon at 16 mph. Energy is huge (2803 morning, 2329 afternoon), but it’s choppy and messy. Thursday is a washout for paddle surfing; honestly, that setup might be more interesting for kite surfing.
Friday, July 17, brings a monster – 13ft SSW swell, period 12 seconds, and energy is off the charts (4681 morning, 4430 afternoon). Winds are light cross-on to cross, so there are waves, but it’s for experts only. Swell this big over 8ft is no joke.
Now, here’s the standout: Saturday, July 18. Morning has a 8ft SW swell with a cross-off breeze and clean conditions (energy 2979). By afternoon, it’s 7ft SW swell with a 14-second period, cross-off winds at 12 mph, but still clean and powerful (energy 4086). This is the pick of the period for experienced surfers who want size and shape.
Sunday, July 19, is almost as good. Morning has a 7ft SSE swell, cross-off winds, clean (energy 2190). Afternoon goes glassy with a 6ft SSE swell (energy 1379) – that’s a dream session for anyone who can handle it.
After that, the surf tapers off. Monday and Tuesday (July 20-21) are smaller, with messy wind. Then Wednesday, July 22, lights up again – 6ft SSW swell, 14-second period, clean cross-off winds in the morning (energy 1219). Another good session.
The rest of the week through to Sunday, July 26, has some solid pulses – 8ft SW swell on Friday morning, 8ft SW again on Saturday morning with clean wind – but the wind tends to get cross-on or messy later in the day. Saturday morning, July 25, is a strong contender: clean, 8ft SW swell, energy 1597.
Overall, the best on offer is Saturday, July 18, for size and cleanliness, with Sunday, July 19’s glassy afternoon as a close second. Keep an eye on that long-range stuff for the following week – it looks promising but less certain this far out.
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.
