The Lowdown

Alright folks, Rusty here. Let’s get stuck into what’s cooking at Fish Boma.

We’ve got a solid run of swell on the horizon. The first real action kicks off Monday afternoon, August 3rd, with a clean 5ft of ESE groundswell. The wind is a light cross-off, making for some excellent, clean lines. The water’s sitting at 63°, which is pretty much normal for this time of year, so no surprises there. The overall energy is strong (1125), so you'll feel that push.

Tuesday morning the 4th sees a shift to a 4ft SW swell, still with light cross-off wind, but it’s a little smaller. The real standout window starts Wednesday morning, August 5th. We’re looking at glassy conditions, a 4ft SSW groundswell, and a very long period of 15 seconds. That’s proper groundswell energy (1148) and it’ll be clean. Wednesday afternoon cranks it up a notch: 7ft of SW swell, still glassy, and the period is even longer at 16 seconds. The energy jumps to 2150. This is the primo window if you’re an experienced surfer. The long period means this reef break will be proper, but it will also be a bit more walled up, so pick your line.

Thursday and Friday the 6th and 7th see the swell size bump up into the 10ft range, but the wind gets messy with cross-onshore breezes, making it choppy. That’s more for the big-wave crew with a tolerance for bumpy conditions. Saturday the 8th is a beauty though – a 8ft SW swell with glassy wind in the morning, dropping to 7ft in the afternoon. Still glassy. That’s another top pick. The energy is very strong (2276).

Things get a bit wild from Sunday the 9th into the next week. Sunday afternoon gets a bit lumpy, but Monday the 10th is a write-off – a massive 16ft to 18ft SSE swell with 40 km/h winds and heavy rain. That’s not surfable for most. The energy is insane (12263), but it’s a mess. Tuesday the 11th is still huge and cross-choppy. If you’re a kiter, that Monday and Tuesday look like a full-on playground; for a surfer, it’s a no-go.

We get a break in the wind on Wednesday the 12th. The swell is still big, 12ft to 10ft, but a strong cross-off wind from the NW cleans it up. That’s a solid window for experienced surfers only. The big highlight for the second week is Thursday morning, August 13th. We’ve got a 13ft SE swell, clean with a light cross-on wind, and the energy is massive (8276). The direction is a bit different, but the quality is there. Friday the 14th drops back into a more manageable 6ft to 6ft range, but it’s not as clean.

The weekend of the 15th and 16th settles into a nice groove. Saturday the 15th is glassy all day with a 5ft to 5ft SW swell. Excellent for a fun session without the heavy crowd pressure, though it can get busy here sometimes. The run ends with a punch on Tuesday the 18th – a 10ft SW swell, clean cross-off wind, and very strong energy (3650). That’s a bold, punchy swell to end the outlook.

The standout: Wednesday morning and afternoon, August 5th. Glassy, stellar groundswell, and a proper reef setup. If you can only pick one window, that’s it.

The big-wave call: Thursday morning, August 13th. That 13ft SE swell is clean, but it’s for experts only.

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.
