The Lowdown

Alright, Rusty here. Let's have a look at what we've got cookin'.

First up, the water at Fish Boma is sitting at 63°, which is pretty much spot on for this time of year. No surprises there.

We've got a bit of a gap before the real action starts. The first solid session is shaping up for Thursday the 30th of July. It's not the biggest day, but that morning is looking tasty. We're talking a solid 6ft of SSW swell with a 13-second period pushing in. That's some proper groundswell energy – a combined energy of 1601 tells you there's plenty of push. The wind is a light 6 mph cross-off from the ENE, keeping the surface clean. This is definitely one for the experienced crew though, as it’s a bit of a beast for the beginners.

Friday the 31st of July stays pretty clean, with a 6ft ESE swell and a gentle cross-off breeze in the morning. It’s a bit of a step down in power, but still a fun wave.

Now, here’s a real standout. Saturday the 1st of August, first light. The swell bumps up to a solid 8ft from the east, with a 9-second period. The wind? It's glassy. Absolute dead calm from the NE at 3 mph. The combined energy is massive at 2076, and the wave comment says it's excellent for experienced surfers. This is the window you want to be in the water.

Sunday the 2nd and Monday the 3rd of August see the swell drop back a little, but with glassy conditions again on the Monday morning as a 4ft SW groundswell rolls in with a 13-second period. That’s a long, clean period, and with no wind, it'll be a dream.

Things get a bit messy from Tuesday the 4th as the wind turns onshore, but that's only for a couple of days.

Then we get another big pulse. Wednesday the 5th of August afternoon sees the swell jumping to 10ft from the SW, with a very long 15-second period and a huge combined energy of 3530. But the wind is a light cross-shore, so it should still be manageable for a big swell. This sets the stage for a run of serious size.

The real gold in this stretch is Friday the 7th of August. The morning is an absolute standout. You’ve got a thumping 10ft SW groundswell, 14-second period, a combined energy of 3751, and glassy conditions – dead calm from the north. This is a serious, powerful swell with perfect conditions. If you’re an expert, this is the day you circle on the calendar.

The first week of August is packed with big, long-period SW swells. A word of caution: swells with periods over 15 seconds, which we saw on the 5th, can sometimes break a bit too straight and fat on a beach break. At a spot like Fish Boma, a reef setup, this long period energy will likely focus up nicely, so that’s a big plus.

The second week rolls in with more action. Sunday the 9th of August morning has a clean 6ft swell, but the wind is howling from the NW at 19 mph. After that, the 10th and 11th look pretty wild and windy, with rain showers and big, messy swell over 12ft – that’s more for the windsurf or kite crew. It's raw.

By the time we get to Wednesday the 12th of August, it settles right back down. Another glassy morning with a 5ft groundswell from the SW. That pattern of clean, glassy mornings with good SW swell holds right through to Friday the 14th. The morning of Thursday the 13th of August is another cracker: 7ft of SW swell at 16 seconds, glassy conditions. A very solid, very clean day.

So, the story is clear. The best windows are the glassy mornings with the big, long-period SW groundswells. The absolute pick of the bunch is Saturday the 1st of August and Friday the 7th of August. Both have excellent conditions and serious power. Don't sleep on these.

Stay safe out there.

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.
