The Lowdown

Alright, Rusty here again, looking at the same stretch. Fish Boma is the only spot worth talking about – a reef break that’s fairly consistent. Water temp is 61°F, running about a degree and a half colder than usual for this time of year, so you’ll want a thicker suit or a bootie.

The first real standout kicks off on Thursday, August 13th and rolls into Friday, August 14th. That’s the best of the bunch. Thursday morning you’ve got a clean 5ft SSW groundswell with a very long 19-second period, a clean offshore breeze from the NNE, and the energy is pumping hard at 4227. It’s set up for experienced surfers, but it’s not punishing – just solid, clean, and juicy. Thursday afternoon drops to a 6ft SW swell, still clean with a light cross-off breeze.

Friday the 14th is a dream. Morning brings a 5ft SW swell with a 16-second period and a nice offshore wind from the NNE. Then Friday afternoon goes glassy with a 4ft SW swell, 15-second period, and zero wind. That’s a flat, glassy, perfect reef day. The energy is moderate at 1074, but the quality is top-tier.

Saturday the 15th has a glassy morning with a 4ft SW swell, but it’s smaller and the energy is down to 657. Still worth a paddle if you missed the earlier days, but not the peak.

From Sunday the 16th through the 21st, the wind turns messy – cross-on and onshore flow. Swell stays between 4ft and 6ft, but the quality drops. The 19th of August has a 8ft SSW swell, but it’s short period at 11 seconds and a light cross-on wind. That’s a lot of lumpy water – better for a kite than a paddle.

We get a second big spike on Sunday, August 23rd. That’s the other standout. A 7ft SW swell with a 13-second period and a clean cross-off breeze from the east. Energy is strong at 1645, and conditions are clean. This one is for the experienced crowd – it’s over 7ft, so it’s not a beginner’s day. The whole day holds up, with the afternoon still giving a clean 6ft.

After that, the 24th and 25th go flat and lumpy, with a weird E swell on the 25th that doesn’t suit the break. The 26th and 27th pick up a little with some glassy moments, but it’s smaller.

So, lock in Thursday the 13th and Friday the 14th for the cleanest, most fun waves. Then Sunday the 23rd for the bigger, cleaner, but more powerful session. Get 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.
