The Lowdown

Alright folks, Rusty here. Let's get into it. We've got one spot on the menu for the next couple of weeks, and it's a beauty, but you've gotta pick your moments.

##

Alright, the main event for the next 16 days is Fish Boma. This is a reef break, and it's fairly consistent, so it's not just a flash in the pan. The water temp is sitting at 64°, which is pretty much average for this time of year, so no surprises there.

The action kicks off on the morning of Tuesday, July 21st. We're looking at a solid 6ft SSW swell with a 14-second period, and the wind is glassy out of the SW. That's clean, that's good. The combined energy is a whopping 1809, which is a lot of power in the water. This is excellent for experienced surfers, but that 6ft is a bit much for beginners. The offshore wind is NNE, so it's breaking nicely over the reef.

However, that afternoon, the wind swings to a cross-shore SE breeze at 6 mph, and the swell jumps to 8ft. The energy bumps up to 2773, but the conditions become marginal. The window is closing.

Wednesday, July 22nd, through Thursday, July 24th, is a bit of a write-off. The wind is cross-on, the swell is 7ft to 10ft, and the energy is still high, but it's choppy. Not the time.

Now, here's the standout. Friday morning, July 24th, is the one to circle. The wind is a light, cross-offshore breeze from the East at 6 mph, and we get a 12ft SSW groundswell with a very long 16-second period. The energy is immense at 6831. This is exceptional surf, but it's only for experts. That size is serious, and the long period means it'll be powerful and walling up. The best spot to be is Fish Boma, as a reef break, it will handle that long-period energy perfectly. It's a gem, but be aware that crowds are possible here.

The weekend of July 26th and 27th holds clean 7ft to 8ft waves with light cross-offshore winds, so it's a great run of surf for the intermediate to advanced crew. The morning of Sunday, July 26th, is glassy with a 7ft SSW swell—perfect for a long session.

We get another big pulse on the morning of Tuesday, July 28th. A 10ft SSW swell with a 14-second period, and it's glassy again. The energy is 3677. That's another excellent session for the experts, but the wind picks up to a strong cross-shore in the afternoon.

The following week looks promising, but less certain. The morning of Wednesday, July 29th, is clean with a 10ft SSW swell, and the wind is cross-offshore. That's a solid option.

We hit a bit of a lull around July 30th. Heavy rain and onshore winds make it a mess.

But then, we get a beautiful run. Friday, July 31st, the morning is glassy with a 6ft, 18-second period swell. That's a lot of period. The energy is 2752. That afternoon, we get a 8ft SW swell, still glassy, and the energy jumps to 3509. That's a fantastic cross-off for the weekend.

Saturday, August 1st, is glassy in the morning with a 7ft swell. The wind is light so it's great.

Sunday, August 2nd, the morning is a standout: a 10ft SW swell with a 11-second period, and the wind is directly offshore from the NNE at 6 mph. The energy is 3056. That's flawless for the experts.

After that, the swell drops. By Monday, August 3rd, we're down to 5ft with a short 7-second period, and the energy is just 689. It's small and weak. The wind is cross-off, but the waves are small and weak.

The rest of the window is a bit of a bust. By August 4th, strong winds and a messy 3ft swell make it a no-go. The morning of August 5th is glassy with a 4ft, 13-second period swell, which is a nice little clean-up for a longboard, but it's not a standout.

So, for the best of the best, Friday morning, July 24th, is your top pick. If you miss that, the Sunday morning, August 2nd, is a close second. Get on 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.
