The Lowdown

Alright, let’s switch it up.

The window starts this Saturday the 5th, and honestly, it’s a slow start. The first few days are pretty average, but there’s some serious firepower building from Sunday the 6th onwards, especially for the crew who can handle a bit of size.

Saturday the 5th is a write-off. We’ve got a messy cross-shore wind around 12-15 mph, and the swell is a weak 5 ft to 5 ft with short, weak period. The water is sitting at 61°, which is a full degree colder than usual for this time of year – you’ll feel that chill.

Sunday the 6th is where it starts to wake up. The morning sees a solid 8 ft SSW groundswell with a very long 19-second period, and a clean cross-off breeze from the east. The combined energy is pumping hard (4977). This is proper, powerful swell. By the afternoon it pushes to 10 ft (5997 combined energy) – that’s expert territory. The size and strength of that swell will see it unloading on the reef at Fish Boma. The wind stays clean cross-off, but it does pick up to 22 mph, so it won’t be glassy – expect some texture but still very ridable for those with experience.

Monday the 7th is the real standout window. Morning brings a lighter 6 mph cross-off breeze with a 7 ft SSW groundswell at 14 seconds. This is clean, powerful, and much more manageable. The combined energy is still very strong (2898). This is easily the best balance of size and conditions in the first week. The reef will be running smooth. The afternoon drops a touch to 6 ft, with the wind swinging cross-shore, but still light.

We then hit a bit of a lull mid-week. Tuesday the 8th has a morning of weak, short-period E swell (5 ft, 9 seconds) with light cross-shore wind – not worth the paddle. The afternoon improves a little with a 3 ft SW groundswell (12 sec) and clean cross-off wind, but it’s small.

Wednesday the 9th is poor – small, onshore, and choppy. A day to stay dry.

Thursday the 10th morning is messy with a building 7 ft SW groundswell and light onshore wind, but the afternoon is the real gem. Clean cross-off wind, 8 ft SW groundswell with a long 16-second period, and combined energy of 3265. That’s a powerful, clean session for experienced surfers. This is your second standout.

Friday the 11th morning holds clean with 7 ft SW swell and light cross-off airs. Then the afternoon goes completely glassy – zero wind, 10 ft SSE swell at 8 seconds. That’s a bit of short-period energy, but on a reef setup like Fish Boma, the lack of any wind makes it a dream. The combined energy is still strong (1893).

Saturday the 12th is blown out by a fresh 22 mph cross-shore. Not your day.

Sunday the 13th morning is an absolute gem – glassy conditions, a solid 10 ft ESE swell, combined energy of 3078. That’s a big, clean, powerful session aimed right at the spot. The wind is dead calm. Unreal. The afternoon turns onshore and messy.

Monday the 14th through Tuesday the 15th sees onshore wind pushing on a 8 ft to 8 ft SW swell. It’s not clean, but the swell is there – more of a windswell setup, short period. This is more of a rough and tumble session for the keen ones.

Wednesday the 16th is a full on mess – 19 mph cross-onshore wind, lumpy, and 8 ft to 10 ft swell. Kite surfers might be eyeing this, but for a paddle, it’s a no-go.

Thursday the 17th morning bounces back nicely – clean cross-off breeze, 10 ft SW swell, 10-second period, combined energy of 2149. That’s a solid, grunty wave for the experienced crew.

Friday the 18th morning is pure joy – glassy conditions, 5 ft SSW groundswell at 12 seconds, combined energy of 1034. It’s smaller, but it will be silky smooth. The reef will be peeling perfectly.

The final weekend (Saturday 19th and Sunday 20th) fades into small, onshore slop, with Sunday the 20th seeing a massive 13 ft SW swell but absolutely hammered by a strong cross-onshore wind – a proper mess, not for paddling.

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.
