The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’ at Fish Boma over the next couple of weeks.

First things first, the water is sitting at about 60°, which is a bit colder than normal for this time of year – a good 3° cooler. So you might want an extra layer for the session, especially if the wind is up. This is a reef break that’s pretty consistent and exposed to the south, but the first standout is coming up quick.

The best of the whole run lands on Tuesday, 15th September. The morning starts with a light cross-on breeze, swell around 5ft out of the east at 11 seconds, and a solid 854 units of wave energy – that’s a moderate, workable push. But the real magic is the Tuesday afternoon: it turns glassy with the wind dropping right out, and the swell settles to 4ft from the east, still at 11 seconds. That’s clean, lined-up reef waves with moderate energy (812 units) and no wind to mess ‘em up. This is the window. It’s for the intermediate crew – this spot can handle a crowd, but it gets busy sometimes, so get out there early.

Wednesday morning (16th) is a write-off; onshore wind at 16 mph and 8ft of messy southwest swell. Not good. Wednesday afternoon cleans up a touch with a cross breeze and 5ft, but it’s marginal.

Thursday, 17th September morning is actually pretty clean with cross-offshore wind and 7ft of southwest swell at 12 seconds. The energy is strong (1652 units). That’s a solid, powerful reef wave but it’s steep. Over 8ft on some of the coming days will be expert territory.

On Friday the 18th afternoon, a new pulse of 10ft from the east-southeast rolls in, but the period is short at 8 seconds. That’s a lot of water moving fast and lumpy – strong energy (2123 units), but it's a windswell and the breeze is up at 19 mph. This looks more like a kite-surfing afternoon than a paddle session.

Friday 25th September morning shows a big 12ft southwest swell with 10-second period and a cross breeze. That's a massive 4813 units of energy – very strong. The wind is light, creating a bit of chop, but for experts only. The consistent run of quality is thin here.

Between the 21st and 23rd of September, the swell drops to 4ft or under with only moderate energy (below 600 units) – a quiet spell for a few days.

Then Monday, 28th September morning fires up again: 10ft from the west-southwest at 9 seconds, cross breeze, and strong energy (2748 units). Another big one for experts, and the wind is light enough to keep it from being a total mess.

Tuesday, 29th September morning is clean again with 8ft from the south at 10 seconds and a light cross breeze – that’s a solid 2553 units of energy. That’s a big, powerful swell. If you’re charging, this is your morning.

The second week has some chunky swells but the winds are often cross or cross-on, and the period is mixed. Nothing really stands out as perfect like that Tuesday afternoon on the 15th. That’s the one.

Stay stoked,
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.
