The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cooking over the next couple of weeks. We’ve got one solid spot on the menu, and it’s going to be a proper run of waves for those who know what they’re doing.

The overall pattern is a long, sustained pulse of solid SW groundswell, with a real standout period around the middle of the month. The water temp is sitting at 62.8°, which is pretty much normal for this time of year, so no need to dig out the thickest rubber just yet.

We kick off on Monday, August 3rd, at Fish Boma. It’s a reef break, exposed to the swell, and it’s fairly consistent. The morning is glassy with a calm sea and a clean 5.6 ft swell from the ESE at 11 seconds. This is intermediate-to-advanced territory – not one for beginners. The combined energy is strong at 1255. The afternoon cleans up with a light cross-off breeze, keeping it tidy.

Tuesday, August 4th, sees a shift in the swell direction to SW. The morning has 3.9 ft of swell with a 12-second period, which is a bit smaller but still fun. The wind is a light cross-off, so it’s clean. The energy drops to moderate at 739. The afternoon gets a bit cross-choppy, so the morning is the call.

Now, Wednesday, August 5th. This is where things get interesting. The morning glass-off with a 3.0 ft, 17-second groundswell from the SSW. That’s a very long period, meaning the energy is deep and powerful at 1098, but it’s a bit small. The real story is the afternoon: 6.9 ft of SW groundswell at 16 seconds, glassy conditions, and a combined energy of 2308. This is a standout window. The long period will make it reel off nicely at this reef, but the sets will be a little more spaced out, so you’ll have time to get in position.

Thursday, August 6th, gets a bit tricky. The morning has 9.8 ft of SW swell at 13 seconds, but the wind is cross-onshore and choppy. The energy is very strong at 3395, but it’s messy. The afternoon is onshore and lumpy. This is more of a kite-surfing setup than a paddle session.

Friday, August 7th, is a redemption day. The afternoon is a ripper: 9.8 ft of SW groundswell at 14 seconds, with a clean cross-off breeze. The energy is massive at 3889. This is an expert-only wave, but for those who can handle it, it’s going to be firing. The morning has rain showers and a cross-shore wind, but it’s still an 8.2 ft swell at 15 seconds.

Saturday, August 8th, and Sunday, August 9th, are messy. The wind gets up, and the surf is poor. A good time to rest the arms.

Monday, August 10th, the afternoon glass-off returns: 6.9 ft of S swell at 11 seconds, clean, and a moderate energy of 1359. A solid session.

Tuesday, August 11th, is a gem. The morning is dead calm, glassy, with 8.2 ft of S groundswell at 13 seconds. The energy is strong at 2284. The afternoon is clean with a cross-off breeze. This is a top-tier window.

Wednesday, August 12th, is more magic. The morning is glassy with 3.6 ft of SSW swell, but the period is a massive 20 seconds. The energy is still strong at 2298. The afternoon is glassy again with 4.9 ft at 20 seconds. This is a very long period groundswell, so it’ll be fat and powerful, perfect for this reef. The spacing between sets will be generous.

Thursday, August 13th, the morning is a standout. Glassy conditions, 8.2 ft of SW swell at 17 seconds. The energy is huge at 3974. This is about as good as it gets for experienced surfers. The afternoon is a bit cross-choppy, but still 9.8 ft of swell.

Friday, August 14th, again, the morning is glassy with 8.2 ft of SW swell at 15 seconds. Energy is 3117. This is another set of perfect conditions. Banks could be changing, but the reef is reliable.

The weekend of August 15th and 16th is all glassy, clean, and solid. Saturday has 5.9 ft of SW swell, and Sunday bumps up to 7.5 ft to 7.9 ft of SW/SSW swell with 14-second periods. The crowds are listed as “sometimes,” so you might see a few other people out, but it’s a reef, so the lineup is usually manageable.

By Monday, August 17th, and Tuesday, August 18th, the wind starts to turn cross-onshore again, and the quality drops. The swell is still there, around 5.6 ft to 7.2 ft, but it’s a bit lumpy and choppy.

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.
