The Lowdown
Alright, Rusty here again. Let's break down what's coming in feet and miles per hour.
We've got a solid run of surf on the horizon, but the first couple of days are going to be a bit of a washout, so don't rush down there just yet. The water temp is sitting at 62°, which is pretty much average for this time of year, nothing to worry about there.
The main event is at Fish Boma, a reef break that's fairly consistent and exposed to the south. The big news is the swell building through the middle of next week. Thursday the 6th and into Friday the 7th is a bit of a mixed bag. Thursday afternoon has a solid 10ft SW groundswell (13-second period) and the combined wave energy is a hefty 2548, but that WSW cross-on wind at 6 mph is going to mess it up. Not worth the paddle.
Friday morning the 7th is where it starts to get interesting. We've got a clean 8ft SW swell, period bumping up to 14 seconds, and a nice ENE cross-offshore breeze at 9 mph. The energy is at 2602, and conditions are looking clean. This is a good window for experienced surfers. The afternoon holds similar size and an even longer 15-second period, pushing energy to 3176, with clean conditions again. This is a standout.
Saturday the 8th and Sunday the 9th are a write-off. Strong onshore winds and rain will chop it all up, making it a messy, unpleasant affair. Monday the 10th is still a bit average.
Now, the real gem. Wednesday morning the 12th has a 6ft SSW groundswell with a very long 20-second period. The energy is a solid 2905. The wind is clean cross-off from the ENE at 9 mph. This is classic reef-swell territory – that long period will wrap in beautifully and offer some great, well-shaped waves. Then Thursday morning the 13th is looking like the pick of the bunch. A clean 5ft SSW swell, 20-second period again, but the kicker is the 3 mph offshore northerly wind. Glassy conditions with energy at 3465. This is absolute perfection for a reef break; long, clean lines, easy paddling between sets. That's your session to circle.
After that, there are still fun waves on offer through to the 16th, with glassy conditions on the 15th and 16th afternoons, but the size drops off. The following week (starting the 17th) gets a bit wind-affected again and the swell becomes more inconsistent.
If I had to call the one or two standouts: it's Thursday morning the 13th of August for the absolute clean, offshore perfection, and Friday morning the 7th of August for the solid, clean swell before the weekend blow-out. Keep your eye on Wednesday the 12th too – that long period could be special.

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.
