Table - best surf conditions forecast for Blacks Beach over the next 16 days.
Alright folks, Rusty here. Let’s have a look at what’s coming up for Blacks Beach.
Honestly, for the next 16 days, it’s a tough stretch. The forecast is littered with poor surf conditions and marginal call-outs, so there’s no single standout that’s gonna have you racing for the car park. We’ve got a long gap of flat, messy energy from the get-go, so don’t expect much over the next week.
The first real hint of anything worth paddling out for shows up on Wednesday, July 9th morning. We’re looking at small, long-period groundswell from the SSW, around 3ft at 16 seconds. That’s a drawn-out period, which means better shape but long waits between sets. The wind is cross-onshore though, so it’ll be a little bumpy. The combined energy of all swells directed here is moderate, at 739. It’s marginal, and with a light cross-onshore breeze, it’s not going to be that clean. For a spot like Blacks that’s exposed and consistent, it’s a bit of a letdown.
The following days, Thursday the 10th through Sunday the 13th, are poor. Onshore and cross-shore winds, dropping energy, and tiny swell. The combined energy drops into the 200-300 range, weak. You’re better off doing something else.
Then, around Saturday, July 18th, we get a little flicker of hope. Morning and afternoon both show a tiny pulse of 3ft SW groundswell, with a period of 18 seconds – very long period. The combined energy climbs back to moderate (582). Still, the wind is cross-onshore, so it’s not clean, but it’s light, so it won’t be a total mess. It’s marginal, but it’s the best we’ve got in the whole window. The water temperature is running much warmer than normal for this time of year, at 70°, so at least you won’t need a thick suit.
To be straight with you, there’s no true standout. If you’re desperate, Saturday the 18th and Sunday the 19th are your best bets – small, long-period SW groundswell, light winds, but don’t expect perfection. The crowds at Blacks Beach can be often, so prepare for company even on a small day. Because it’s an exposed break, it picks up a lot of energy, but the quality just isn’t there this run.
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.
