Alright folks, Rusty here. Let’s have a look at the next run of days for Back Beach.
This place is exposed to the south-west and it’s a consistent break, so it’s always got a chance. The water temperature is about average for this time of year, nothing wild there.
The first few days (Friday the 10th through Saturday the 11th) are pretty average. The swell is in the 4ft to 6ft range out of the WSW, but the wind is messy—onshore or cross-onshore—making it a bit choppy and not worth racing for. The energy is moderate (1060). It’s a bit of a wait, but look at Sunday the 12th of July. That morning, we get a clean, cross-offshore breeze with an east wind, and the swell jumps to 8ft from the SW with a long 16-second period. That’s a proper groundswell with moderate to strong energy (3559). This is a standout for experienced surfers; it’s too big for beginners, but for those with the skill, the morning is money.
Monday the 13th is a big one. The swell hits 10ft from the SW with a 17-second period, so very long-period groundswell. The energy is very strong (5364). The wind is offshore in the morning, but honestly, the swell is too big for this break. It’s a real expert-only day, and even then, it might be a bit unruly.
Tuesday the 14th is still excellent for experienced surfers. The swell is 8ft out of the WSW with a 15-second period, and the wind is offshore from the NE in the morning. Strong energy again (3038). Clean, powerful, but still heavy.
The rest of the week (Wednesday the 15th to Saturday the 18th) gets a bit tricky. The swell stays up, but the wind turns onshore or cross-shore, with some rain and poor conditions. The afternoon of the 18th has a 15ft swell, but it’s cross-shore and messy. The setup looks more interesting for kite surfing than paddle surfing through that period.
Sunday the 19th cleans up again with a cross-offshore breeze and a 10ft to 12ft swell, but it’s still too big for most. That’s an expert-only window.
The real standout in the second week is Wednesday the 22nd of July. Morning session: 8ft from the WSW with a 16-second period, light offshore wind from the NE, and clean conditions. Strong energy (3074). That’s a beautiful, powerful, clean day for experienced surfers. Crowds are possible here, so get in early.
The run ends strong on Saturday the 25th of July. The morning is glassy, dead calm, with a 8ft WSW swell and a very long 18-second period. That’s a very strong groundswell (4204) and it will be clean as a whistle. Perfect for the experienced crew.
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.
