The Lowdown

Alright, Rusty here. Let’s have a look at the outlook for Fish Boma.

We’ve got a solid window of surf coming up, but you’ll have to be patient early on. The first real opportunity is Wednesday afternoon, September 2nd. It’s not the best though – we’re looking at an 8ft SW swell with a cross-shore wind, and the wave energy is strong (2346). The water temp is sitting at 60°, which is about 3° colder than average for this time of year, so a bit of a nip in the air and water.

Thursday morning, September 3rd, is where things start to look up. The swell drops to a cleaner 5ft from the SW, with a 12-second period, and it goes glassy. That’s a major positive – you’ll get clean, lined-up waves with a combined energy of 1062. It’s excellent for experienced surfers, so if you’ve got the skills, get out there early. The afternoon turns ugly though – heavy rain and a fresh cross-onshore wind kicking up an 12ft SSE windswell (2471 energy) that will be a lumpy mess.

The next real standout is Monday morning, September 7th. Glassy conditions again, with a 6ft SSW swell, but check this out – the period is a very long 14 seconds. That’s groundswell, and at Fish Boma it should peel nicely. The energy is strong at 2248. This is top-tier for experienced surfers. Monday afternoon stays rideable with a light cross-shore, but the glass is gone.

Then, Sunday, September 6th is worth a mention too. Both the morning and afternoon have a long-period SSW swell (19 and 18 seconds!) with clean, cross-off winds. The energy is enormous – morning is 3382, afternoon is a massive 5145. This is powerful, straight-running groundswell, so it’ll be best on the point, not so much if it’s a beach break. For experienced surfers, this is a serious session.

After that, it gets quieter. Tuesday morning, September 8th has a small 4ft E swell with glassy conditions – good for a cruise, but not a standout. The following days drop off with smaller swells and increasing onshore winds. There’s a gap of several days where the surf is poor or marginal, until Monday morning, September 14th, when a 6ft SSW groundswell (13-second period) and clean cross-off winds bring back some quality. That’s a promising session, but it’s a week and a half out, so hold off on booking your flights.

Overall, the best windows are Thursday morning Sept 3rd, Sunday Sept 6th, and Monday morning Sept 7th. Sunday is the standout for power and long, grinding waves – but only for experts. Monday morning is glassy perfection. Get on it.

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.
