The Lowdown
Alright folks, Rusty here. Let’s get straight into it. We’ve got a bit of a wait ahead for the good stuff. The first few days are a write-off, more of a tease than anything else.
We’re looking at Blacks Beach, and it’s a slow start. Thursday the 3rd is a no-go – the energy is there (613) but the report says the surf is poor. The water is a very unusual 75°, which is much warmer than normal for this time of year, feels like a bath.
The pattern really starts to pick up from Monday the 7th. That’s where the westerly swell starts to build. We’ll see a consistent 7ft swell from the SSW on Monday morning, with a period of 14 seconds. The combined energy jumps to 1659, which is strong. The wind is offshore from the WNW, so it’ll be clean. That’s your standout window. It’s a solid, powerful groundswell, and Blacks is an exposed reef that handles it well. It’s a bit much for beginners at over 6ft, but for the experienced crew, that Monday morning session on the 7th is the one.
Tuesday the 8th holds similar size at 6ft from the SSW, with the wind still offshore. The energy is still strong at 1296. The period drops to 13 seconds, but it’s still a quality wave. Wednesday the 9th sees the swell start to drop back to 5ft, but the wind stays onshore, so it’s a bit more mixed.
After that, the wind stays onshore for a lot of the second week. The swell drops off significantly. There’s a window on the 16th and 17th where the wind is offshore again, but the swell is tiny, down to 2ft. The period on the 17th is a very long 22 seconds, meaning long, slow lines – but with no height, it’s frustrating. The energy is low (462). It’s not really surfable for a proper session.
So, to be blunt: the first week is a slow burn, but Monday the 7th is the clear winner. A solid, clean, powerful swell at Blacks Beach. Don’t expect much in the second week; it’s a waiting game after that.
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.
