The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the menu for the next couple of weeks.

Alright, the swell window is looking pretty active, but the timing is a bit of a mixed bag. We’ve got some solid groundswell pulses coming through, but the wind is going to be our main dance partner. The first real standout is shaping up for the early part of September, with a good run of strong, clean conditions.

For the best bet, I’m looking at Fish Boma (a reef break). This spot is exposed to the S and SW swells, and we’ve got a couple of very promising days. The Tuesday the 1st of September looks great, with a clean 8 ft to 8 ft swell from the SW, a solid 12 to 13 second period, and light offshore winds all day. The wind is dead on from the SW, which is what we want here. The water is much colder than normal for this time of year, sitting at 59° with a -4° anomaly, so you’ll want a good thick suit. The combined swell energy is pushing into the strong range (1525 to 2154), which means there’s plenty of power in the water. This is a solid intermediate-level wave, and with the crowds being “sometimes,” you might actually have a few sets to yourself.

A real standout for the experienced crew is the Wednesday the 2nd of September. The swell is pumping at 10 ft from the SW with a very long period of 14 seconds, and the combined energy is massive (3330). The morning has a cross-shore wind, but the afternoon cleans right up with a cross-offshore breeze from the E. That’s a proper, powerful groundswell at a reef break, which is a dream combination. This is expert territory only at that size, as it’s over 8 ft.

Later in the second week, there’s a promising but less certain window. The Monday the 14th of September has a big 12 ft swell from the E with a 10-second period, and the combined energy is huge (4806). The wind is light and cross-on in the morning, but the afternoon turns light and cross-shore. The water temp anomaly isn’t listed, so we’ll call it average for early September. This is a big, powerful swell, and with it being a reef break, the long-period energy will wrap in nicely. Again, this is for the experts.

There are a few other days with surfable waves, but the wind or chop makes them less appealing. The run from the 3rd to the 5th of September is a write-off due to strong onshore winds and lumpy conditions. The swell on the 4th of September hits 15 ft with a fresh cross-onshore wind, which is more of a kitesurfing setup than a paddle session. The period is short (8-11 seconds), which makes for a choppy, less powerful wave.

The 10th of September (Thursday morning) is a gem for the smaller wave crew. It’s glassy, with a 5 ft E swell at 10 seconds. That’s clean, fun, and accessible for most.

Overall, the first week has the best combination of size and wind. The second week has some serious size, but keep an eye on the wind updates. For the best of the best, that Wednesday the 2nd of September is the one to circle on the calendar.

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.

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.
