Alright folks, Rusty here with the outlook for Fish Boma. We've got a solid 16-day window ahead, so let’s get into it.
First up, the water temperature is sitting at 63°F, which is about normal for this time of year so don't expect any surprises there.
The week kicks off proper on Tuesday the 7th of July. We've got a solid SW groundswell running, 6ft of it with a nice long 12-second period, and the afternoon turns absolutely glassy. That's premium. The combined energy is thumping at 1037 (moderate), and for an intermediate crew, this is going to be clean and rippable. Fish Boma is an exposed reef and it's picking up that S-optimum swell perfectly.
Wednesday the 8th sees the swell bump up to 7ft from the SW, but the wind swings cross-on and kicks up a chop. The energy jumps to 2323 (strong) but the quality drops right off. Not our day.
Thursday the 9th and Friday the 10th are pumping with 10ft swells from the SSW. That’s big. The combined energy hits 3324 and then 3745 (strong to very strong). This is expert territory only. Friday afternoon saves the week though – the wind goes glassy again, the swell holds at 10ft with a 13-second period, and the energy is 3294. For the crew who can handle it, that Friday arvo session will be unforgettable.
Saturday the 11th is cleaner with a 7ft SSW swell and cross-off winds. The energy eases to 1360 (moderate). A very good window for those looking for a solid wave without the full-on size.
As we roll into the second week, things settle down. Sunday the 12th through Tuesday the 14th offer nice, clean waves in the 4ft to 5ft range with glassy mornings. The swell shifts more ESE, and the energy drops to the 400-600 range (weak to moderate). Perfect for the log or a fun intermediate board.
Wednesday the 15th gets blown out – strong winds and rain. Skip it.
Thursday the 16th sees another pulse of SW swell at 7ft (energy 1526, strong), but the wind is on it, making it messy and lumpy. Not a paddler's friend.
Friday the 17th and Saturday the 18th bring a return to form. Glassy mornings and clean offshores with 4ft to 6ft swells. The energy is back in the moderate range (622 to 885). Good, fun surf.
Sunday the 19th is small and a bit crossed up. The standout is Monday the 20th of July – a glassy morning with a crisp 6ft WSW swell, 12-second period, and energy of 1129 (moderate). That's a beautiful, clean left-hander waiting for you.
Tuesday the 21st onward fades fast. Small and weak, down to 2ft by Wednesday the 22nd. The run is done.
The Pick: No question, it's Friday afternoon the 10th of July for the experienced crew – big 10ft SSW groundswell with glassy conditions. For the everyday surfer, Tuesday the 7th afternoon or Monday the 20th morning are your golden windows.
Keep your eyes on the horizon, folks.
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.
