Alright, folks, Rusty here. Let’s talk about what’s going on at Back Beach.

The first few days are a real heavy-hitter – plenty of swell, but it’s gonna be too much for most of us. We’ve got a solid groundswell from the WSW with a very long period of 16 seconds and a massive combined energy of 4753. That’s a lot of power. The water temp is about 68°F, which is pretty normal for the time of year, nothing to write home about.

The standout run kicks off on Wednesday, July 8th. The morning is the pick of the week. The swell drops to 7ft, still from the WSW, but the period is a long 14 seconds. The wind is light from the north, cross-offshore, and it’s going to be clean. The combined energy is still a strong 3040. This is excellent surf for experienced surfers. The afternoon is onshore, but the morning is where it’s at.

Thursday, July 9th is another cracker. The morning session is glassy with an 8ft swell from the WSW and a 15-second period. The combined energy is 2746, and the wind is dead calm. That’s as clean as it gets. This is a real treat for the crew who can handle the size.

Friday, July 10th sees the swell drop to 6ft, still from the WSW, with a 13-second period. The morning is glassy again, and the combined energy is 922. This is more manageable, very good conditions, and the crowd factor is likely here as it’s a consistent spot. Expect some company.

The weekend gets a bit trickier. Saturday, July 11th has a 5ft swell from the SW and a 14-second period, with cross-offshore wind. It’s clean, but the energy is only 749. It’s surfable, but not a standout. Sunday, July 12th is similar, with a 6ft swell and a 13-second period, but the energy picks up to 2219. The wind is cross-offshore in the morning, so it’s clean, but the consistency is a bit marginal.

The following week, from July 13th onward, the swell jumps back up. Monday the 13th has a 10ft swell with a 17-second period – that’s a very long period groundswell, and the combined energy is a massive 5214. The wind is cross-offshore, so it’s clean, but it’s too big for all but the most experienced. This is expert-only territory.

Tuesday, July 14th is a great call. The swell is 8ft, 15-second period, and the wind is offshore from the northeast in the morning. The combined energy is 2207. It’s clean and powerful. The afternoon goes glassy with a 8ft swell. This is another excellent day for expert surfers.

After that, the wind gets stronger. Wednesday, July 15th has a fresh offshore breeze, but it’s 19 mph, which is a lot. The swell is 7ft, but that wind will make it tricky. The following days are a mix of onshore and cross-shore winds, with the swell staying big. By July 17th, we’re looking at 13ft swell with a 16-second period – that’s an absolute beast, and the combined energy is over 8000. It’s a no-go for paddling, but if you’ve got a kite, that setup is going to be interesting.

The last few days, around July 21st and 22nd, start to settle down. The swell drops to 4ft to 6ft, with good offshore winds. The period is still a solid 14 to 15 seconds, so the waves will have shape. The energy is moderate, around 900 to 1500. This is where the beginners and the rest of us can get back in the water.

Overall, the best on offer is the morning of Wednesday, July 8th and the morning of Thursday, July 9th. Those are the standouts. The big stuff in the second week is for experts only, and the wind is going to be a factor. Keep an eye on the forecast, but for now, get those windows marked.

Rusty out.

Information about the Back Beach Surf forecast

The above surf forecast table for Back Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Back Beach can be found by selecting the local surf guide option on the grey menu. Our Back Beach 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 (Back Beach) 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 Back Beach 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.
