The Lowdown
Alright, grab a coffee and listen up. Rusty here, lookin’ at the charts for Blacks Beach. Honestly, it’s a bit of a tough stretch ahead. We’re starting with some small, messy waves and the wind is all wrong for most of the run. The water is sitting at a very unusual 72°, which is a lot warmer than normal for this time of year – feels like a bathtub.
The first week is pretty much a write-off. From Monday the 13th right through to the weekend, we’ve got tiny, poor-quality swell. The wind is either cross-on or onshore, leaving it chopped and crumbly. The combined energy is weak to moderate at best, with readings like 336 and 228, but the quality is just not there. You’ll be chasing 2 ft to 4 ft scraps from the SSW or SW, with a period around 13 to 18 seconds, but it’s all wasted by the breeze. This is a stretch of at least five days with no real recommendation.
Things start to look a little more interesting towards the end of the second week. Keep an eye on Saturday the 26th of July. The morning shows a promising 3 ft SSW swell, but the period jumps to 19 seconds. That’s a very long-period groundswell, which for a beach break like Blacks can break a bit straight and make the paddle out a bit tricky. The combined energy is strong (835), and the wind is a light cross-on from the WSW at 15 km/h. It’s still a bit onshore, but it’s the best we’ve got in the whole window. The afternoon is a bit smaller.
The real standout, if you can wait for it, is Saturday the 25th of July. The afternoon session has a 4 ft swell from the SSW at 12 seconds, with a massive combined energy of 721. The wind is from the W at 15 km/h, which is onshore for Blacks, so it won’t be perfect, but the size and energy are there. It’s a marginal call, but it’s the biggest push of the forecast. Get on it early before the tide or wind kills it.
Overall, it’s a lean two weeks. The first week is a dud, and the second week has a couple of days that are worth a look if you’re desperate for a paddle. The 25th and 26th of July are your best shots, but don’t expect perfection.
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.
