The Lowdown

Alright, this is Rusty. Let's have a proper look at what’s coming down the line for Fish Boma. This is a reef break, exposed to the south, so it needs the right angle to fire. The water temp is about average for this time of year, nothing wild to report there. We've got a solid 16-day window, but it starts off a bit messy.

The first few days are a write-off, honestly. Monday the 10th is a no-go with a choppy, cross-onshore wind and a dodgy 8.2ft swell. The energy is decent but all over the place (1743). Tuesday the 11th cleans up a bit with cross-offshore winds, but the swell is short-period junk, especially that afternoon ESE swell at 8 seconds. Not worth paddling out for. Wednesday the 12th is where we start to see some real promise.

The Pick of the Fortnight

Thursday the 13th is the standout. The morning has a clean 5.6ft SSW groundswell with a long, powerful 19-second period and gentle cross-offshore winds. The wave energy is pumping (4711). It’s solid but manageable for an intermediate. The afternoon is just as good, with a 6.9ft SW swell and 18-second period, also clean. This is the kind of day you call in sick for. Friday the 14th is also a beauty, with a glassy morning, 4.6ft SW groundswell, and light offshore winds. That afternoon turns absolutely glassy with 4.3ft waves – pure velvet.

The following week starts strong. Monday the 17th sees a glassy 7.2ft SW swell, perfect for experienced surfers. Tuesday the 18th keeps that quality going with glassy 5.6ft surf. But then it gets a bit jumbled towards the 20th and 21st with onshore winds and a shorter-period swell. Don't bother.

However, the end of the window is another cracker. Sunday the 23rd afternoon is massive – an 11.5ft SSW groundswell with a 15-second period and clean cross-offshore winds. The energy reading is exceptional (5268). This is for experts only, but if you have the skills, it’s a world-class session. Monday the 24th is still huge and clean, with 8.2ft SSW swell, but the wind gets a little cross-on, so it won’t be as perfect as the Sunday afternoon. Tuesday the 25th rounds it out nicely with a glassy 5.9ft ESE swell, a great way to finish the run.

Expect some company at Fish Boma, especially on the good days – crowds can show up here. The period is long on the best swells (over 15 seconds), so expect proper groundswell lines with long waits between sets, making paddling out easier. This setup will be perfect for the reef.

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.
