The Lowdown
Alright, Rusty here. Let's take a look at what's on the menu for the next couple of weeks.
It's a bit of a slow burn, to be honest. We're looking at a stretch of fairly average, small surf for the next week or so, with a lot of cross-onshore winds messing with the surface. The water is running at a very warm 74°, which is way above normal for this time of year, so at least you won't need a thick wetsuit.
The first rumble of proper energy shows up around Saturday the 1st of August. We've got a new SSW swell arriving, pushing chest to head-high waves at 5ft to 6ft. The period is a solid 12 seconds, so there's some real groundswell in there, giving the waves some shape. The combined energy hits a strong 897 (Sunday morning). The best part? The wind is looking light and offshore from the West, which should clean things up nicely. This is the standout window of the whole forecast. The break is Blacks Beach, and it's a consistent, exposed spot that handles this direction well. With a solid 6ft, this is going to be for experienced surfers; it'll be too much for beginners. The crowd factor is "often," so expect company for these clean, well-shaped waves.
That little pulse fades quickly. By Sunday afternoon the 2nd of August, we're back to small, weak waves with the energy dropping to 244. The wind swings back to a light cross-on, and the quality drops right off. After that, the forecast is pretty grim. From Monday the 3rd of August all the way through to Sunday the 9th of August, we've got a flat spell. The swell is tiny, barely breaking 1ft to 3ft, with periods all over the shop and pretty much no energy. The wind conditions are mostly onshore or light, producing nothing worth waxing up for. It's a solid week of nothing.
So, to sum it up: the only real call to action is the morning of Saturday the 1st of August. Get on it early for a proper session. The rest of the window is a write-off.
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.
