The Lowdown
Alright, let’s break this down. Blacks Beach is taking its sweet time. The first few days are total skunk territory—tiny, weak swell and a cross-shore breeze that’s just killing any chance of a wave. You’re looking at a solid 4-day gap of nothing until Monday the 20th.
Monday morning finally shows some life, with a SSW swell hitting 5 feet, but the wind is onshore and messy. The wave energy is moderate (661), but it’s a choppy mess. That trend sticks around through the week, with swell hanging between 3 and 4 feet, but that cross-onshore wind from the SW never lets up. It’s not unrideable, but it’s not clean.
The big moment is Saturday the 25th. We get a solid pulse of SSW swell, pushing 6 feet in the morning. The combined energy jumps to 2114, which is strong. That’s the biggest wave of the whole 16-day window. The catch: the wind is still cross-onshore from the SW at 9 mph, so it’s going to be bumpy and tough. This is expert-only territory at that size. It’s a beach break, so that long-period groundswell (14 seconds) will be closing out fast, but for the crew who can handle it, there will be some heavy, powerful drops.
After that, the swell drops back into the 3-to-4-foot range through the end of July and into the first of August, but the wind never really gets right. It stays cross-onshore or onshore. The water temp is about average for the season.
Bottom line: Saturday the 25th is the one to circle if you’re an expert looking for a heavy, powerful session, but don’t expect it to be glassy. The rest of the window is a grind for marginal, sloppy waves. If you’re a kiter, that bumpy, strong energy on the 25th looks a lot more fun than a paddle.

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.
