Table - best surf conditions forecast for Blacks Beach over the next 16 days.
Alright, Rusty here. Let’s break down what’s happening at Blacks Beach. Honestly, it’s looking like a bit of a drought for us right now.
We kick things off on Saturday afternoon, the 11th. There’s a 3 ft swell from the SSW, with a 15-second period – that’s a real groundswell with decent energy, but the wind is cross-on from the SW at 6 mph, so the surface is a little off. The water’s 72°, which is about 5° warmer than normal for this time of year, so that’s a treat. Still, the forecast is calling it marginal, so this is the best we’ve got for a while, and that’s not saying much.
The next few days – Sunday the 12th all the way through to Tuesday the 15th – it’s just poor. Swells dropping to 2 ft or less, winds are onshore or cross-on. Energy readings in the doldrums. Leave your board in the car.
We get a little pulse on Thursday the 16th, but it’s only 3 ft with a weak 8-second period. That’s just wind chop, and the cross-on breeze makes it choppy. Not worth it.
Now, the real chance shows up later on. Around Saturday the 25th of July, we’ve got a 4 ft swell from the SW with a very long 21-second period, and the energy is huge. The wind is light offshore from the west at 6 mph. That could be clean and powerful, but with that long period and this being a beach break, it might be a bit tricky. It’s definitely expert territory if the size picks up. Sunday the 26th also has a similar look – 4 ft from the SW, 19-second period, with a light cross-on wind. If you can handle the paddle and the crowd, it could be the best day of the stretch.
Bottom line: if you’re an experienced surfer, hold out for that last week. Beginners, stay on the sand. For now, the conditions are just not giving us much to work with.
Rusty.

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