G'day, Rusty here. We've only got one spot on the radar for the next couple of weeks, and that's Back Beach. It's an exposed beach break that's consistent, so it's always trying to offer something. The water temp is sitting at 68° right now, which is about average for this time of year, nothing out of the ordinary.

First chance for a paddle is going to be this Friday afternoon, the 3rd of July. We've got a solid 7ft SW groundswell rolling in with a 14-second period, packing moderate to strong energy (1899). The wind's coming out of the east at 9 mph, which is a cross-off breeze, so conditions should be clean. This is definitely one for the experienced crew though – that's a decent size for a beach break. The crowd factor is a "sometimes" thing, so there's a chance you'll have some company, but nothing too hectic.

Saturday the 4th is looking even better in the afternoon. The swell holds at 7ft from the SW, but the period bumps up to 17 seconds (that's a long-period groundswell, so the waves will have plenty of punch and shape). The wind swings around to the north-northeast at just 9 mph, giving us a gentle offshore breeze. This is the standout of the whole run: the wave energy is strong (2827), and those offshore conditions will have the lines looking silky. Saturday morning is also a goer with a 19 mph NE offshore, but the afternoon is the pick for sure. Again, experts only at this size.

Sunday the 5th sees the swell drop a bit. Morning has 5ft from the SW, 15-second period, but the NNW wind at 12 mph is a cross-off. The energy is moderate (881), so it's a bit weaker. The afternoon session gets messy with a westerly cross-on breeze – not worth getting too excited about.

Now, Monday the 6th through Tuesday the 7th, we get a big pulse. Swell hits 10ft from the WSW with a 16-second period. That's a lot of water moving. The combined wave energy is very strong (over 4000). The wind is mostly cross-off from the ESE on Monday, and Tuesday morning stays clean, but this is only for absolute experts. For most, it's going to be a washing machine, and honestly, it might be more interesting for the kite surfing crew than paddle surfing at that size on a beach break.

Wednesday the 8th drops back to a more manageable 7ft to 7ft from the WSW. Morning has a nice cross-off from the NNE, keeping it clean. The energy is moderate (1927). It's a decent option, but not the top pick.

The rest of the run through to the 18th of July is a mixed bag. There are plenty of days with 7ft to 7ft SW swell and decent winds, like the 13th and the 16th of July, which both look clean with cross-off or offshore breezes. The 16th of July (Thursday) is another solid option, with 7ft SW swell and a moderate offshore wind from the NE.

But keep an eye on the 15th of July (Wednesday morning). It's a smaller day, 4ft from the WSW, but the wind is offshore from the ENE at 16 mph, making for some clean, fun waves that are more manageable. The 17th of July (Friday afternoon) is also a little gem with 6ft SW swell and a gentle offshore from the NNE.

The last couple of days, the 18th of July, get blown out with strong winds and rain, so that's where we sign off. The overall pick? Saturday afternoon the 4th of July. That long-period SW groundswell with the gentle offshore wind is going to be the cleanest, most powerful session on offer. Saturday morning the 4th is a close second.

Rusty.

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.
