The Lowdown
Alright, this is a tough one to call. Let's be straight with you.
Lookin' at the whole 16-day window, honestly, it's a bit of a bummer. We've got a real dry spell on our hands. The first surf worth paddling out for isn't even until Wednesday the 29th of July, and even then, it's a tease. After that, things go quiet for a long stretch. From Thursday the 30th of July all the way through to the end of the forecast, it's a wasteland of "poor surf conditions" – basically nothing doing. There's a flicker of life on Sunday the 9th of August, but it's still just marginal. So, we're looking at a big gap with no real recommendations.
The only spot in the game is Blacks Beach. The one semi-decent window is Wednesday afternoon, the 29th of July. We've got a clean 4 ft swell from the SSW, with a long period of 16 seconds. That's a proper groundswell with some energy behind it (combined energy of 757). The water is cookin' at 76°, which is a massive 9° warmer than normal for this time of year – that's very unusual, almost like a warm bath. The wind is blowing from the W at 9 mph, which is straight offshore for Blacks. That's a major positive, it'll keep the faces clean. But here's the rub: the swell direction is SSW, but this break really wants it from the WNW. So it's a bit of a mismatch. The wave comment says "marginal surf forecast," and the score backs that up. It's not a total loss, but it's not a standout either.
After that, it's all cross-onshore or onshore breezes, tiny swell that's all under 3 ft, and the energy just drops off a cliff. The longer period swells that pop up later in the run, like a 19-second pulse on the 7th of August, are only 2 ft – all show and no go. Blacks is an exposed beach break, so with the small, weak energy and tricky winds, it's honestly more of a kite-surfing setup than a paddle-surfing one for the vast majority of this period.
If you're desperate for a paddle on the 29th, you might find a few lined-up waves, but don't expect much. The rest of the window is a write-off. Forecasts can change, but right now, this run looks pretty normal for a quiet spell around here.

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.
