The Lowdown
Alright folks, Rusty here. Let’s be straight with you. The next couple of weeks are looking pretty flat and disappointing for Blacks Beach. We've got a long stretch of small, weak swell with mostly onshore or cross-onshore winds. It’s a bummer, but it is what it is.
The first good window we see is around Friday the 14th. The energy picks up a bit, hitting that moderate range (603-721), with a solid 2.5-3ft of SSW swell. It’s still not huge, but it’s the most interesting we’ve got. The period is a solid 18 seconds, which is a proper groundswell, giving the waves some push. The wind is light and offshore, so it could be clean. But it's still marked as marginal, so keep your expectations in check. This is the standout of the whole run, honestly.
Before that, from now until the 13th, it's pretty grim. Swell heights hover around 1.5-3ft, and the energy is in the weak to moderate range (119-603). The wind is mostly light and offshore in the mornings, which is nice, but the swell just isn't there. It looks more like a lake than a surf break. Honestly, for most of this time, the conditions look better for a paddle than a wave.
The second week, from the 15th onward, stays in that same poor range. Swell drops back to 2-3.5ft with shorter periods, and wind switches to a cross-onshore W/NW flow, chopping things up. There's nothing that gets me excited.
So, bottom line: the only real window to look at is the 14th. It's not going to be a classic, but it’s the best we’ve got. The water is running much warmer than average for this time of year, so you won't need a thick suit. Save your energy for that Friday.

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.
