The Lowdown
Alright, let me tell you about the waves coming up for Fish Boma. We've got a real mixed bag on the cards here, but there are a couple of sessions that'll be worth getting up early for.
The coming week kicks off pretty slow. Sunday the 23rd and Monday the 24th are a bit of a write-off. There's swell around, 5ft to 7ft from the southwest, but the conditions are marginal, and the tide just isn't playing ball. The wave energy is moderate, sitting around the 1244 to 1352 range on Sunday, but it's not clean. You'd be better off waiting.
Hold on, because Tuesday the 25th is the standout. The morning is looking absolutely mint. We've got a solid 8ft groundswell rolling in from the southwest, powered up by a very long 14-second period, and the combined swell energy is very strong at 2756. That size is getting into the experienced-only territory, but with glassy conditions and zero wind, Fish Boma will be a rippable, clean reef wave. This is the session you don't want to miss.
Wednesday the 26th through to Friday the 28th sees the swell ease and winds turn cross-off. Wednesday morning still has a decent 7ft from the south-southwest with strong energy (1923), but a moderate breeze makes it less perfect than Tuesday. Thursday the 27th is another beauty for the experienced crew. The morning offers 6ft with a glassy surface and strong energy (1571). The swell period is still long at 12 seconds, so expect good shape. Towards the end of the week, Friday afternoon shapes up nicely with clean 4ft from the south, though the energy drops to moderate levels (828).
After that, we hit a lull. Saturday the 29th and Sunday the 30th are poor. Saturday is particularly messy with choppy cross-onshore winds. The swell drops right off and the quality is gone for a few days.
Now for the second week, we've got some big, powerful pulses to look forward to. Tuesday the 1st of September has the potential to be a real standout for experienced surfers. The morning brings an 8ft southwest groundswell with a long 13-second period and very strong energy (2535). The winds are light onshore, so it won't be pristine, but the power is there. Wednesday the 2nd afternoon is one for the big-wave chargers only. We're looking at an 12ft southwest swell with a 14-second period and super strong energy (5464). The wind is light cross-onshore, making it messy on top of being huge. Thursday the 3rd is even bigger, with a 15ft swell hitting in the afternoon, but a fresh breeze will make it lumpy and challenging. The energy is immense at 7265. Friday the 4th and Saturday the 5th remain big and powerful, but winds and consistency will keep things from being perfect. The swell hangs around through to the end of the period on Monday the 7th, staying big but often blown out. There are a couple of clean mornings, like Sunday the 6th afternoon with a clean 6ft southwest swell (1516), but the week is dominated by solid, expert-level surf.

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.
