Alright folks, Rusty here. Let’s have a look at what’s on the cards for our local stretch.

We’ve got a bit of a slow start, but once it kicks in, it’s going to be a wild ride, especially for the experienced crew. The first real action is this Saturday afternoon, July 11th, at Fish Boma. A solid 8 ft SSW swell rolls in with a 12-second period, packing a hefty 1662 (moderate to strong combined energy). The water's sitting at 62°F, which is about average for the time of year. The wind is a cross-off from the east at 9 mph, so that’s going to keep it reasonably clean. This is one for the intermediates and above.

Sunday morning, July 12th, is another standout. The swell drops to 5 ft from the SSW, but the period stays at 11 seconds, and the east wind is lighter at 6 mph, still cross-off. The energy drops to 1021, but it’s still got some push. A really fun, clean session.

Then we hit a bit of a lull on Monday and Tuesday, July 13th and 14th. The swell drops way down, and while the wind goes glassy on Monday morning, it’s a small, short-period ESE swell at 5 ft and 8 seconds. Fine for a longboard or a twilight paddle, but not a standout.

The real buzz starts building again for Thursday, July 16th. A big 10 ft SW groundswell with a 14-second period hits in the morning. The energy reading is a massive 3209, so there’s a ton of power. The wind is light cross-shore from the west, so it’s not perfect, but for experienced surfers, this is the start of something special. This is a big, powerful ocean swell, so it’s going to be heavy and best suited for a reef setup like Fish Boma.

The absolute highlight of the whole forecast, and I mean the one you circle in red, is Wednesday, July 22nd. The morning is calling for a 13 ft SW groundswell with a ridiculous 16-second period. The combined energy is off the charts at 7847, and the wind is dead calm – glassy. This is an exceptional, expert-only session. The afternoon keeps the power with a 15 ft WSW swell, but a bit of cross-on wind creeps in. Still, for the experienced charger, this is the day.

The following week keeps the big swell theme going. Thursday, July 23rd, serves up 10 ft SW swells with glassy conditions in the morning and afternoon. Then Friday, July 24th, is another monster. The morning is a 15 ft SSW swell with a 16-second period, but the wind is a moderate cross-on, making it choppy. The afternoon, however, is where it’s at: 13 ft SW, 16 seconds, and glassy as glass with an energy reading of 7305. Another exceptional, expert-only window.

The final weekend, July 25th-26th, keeps the quality high. Saturday afternoon with a 10 ft SSW swell and clean cross-off wind, and Sunday glassy with an 12 ft S swell. The energy is still huge, around 3000-3300.

So, the pick of the fortnight? Without a doubt, the morning of Wednesday, July 22nd, and the afternoon of Friday, July 24th. Both are massive, long-period groundswells with glassy conditions. Fish Boma is going to be a beast. Just remember, this is expert territory; the crowd will be there, but it will be worth it.

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.
