The Lowdown
Alright folks, Rusty here. Let’s take a look at what the ocean’s got cookin’ for us.
First up, the water temp is sittin’ right around average for this time of year, so nothin’ wild there.
Honestly, the next few days are a bit of a snoozer. We’ve got a real flat spell from Tuesday, July 14th, all the way through to about Wednesday, July 22nd. The waves that do show are tiny, weak, and messy – we’re looking at combined swell energies struggling in the low-to-mid hundreds (228 to 735), and the wind just won’t cooperate. Most of the time it’s a cross-onshore or onshore breeze, turning the ocean into a choppy, bumpy mess. That’s not surf, that’s a washing machine. If you’re itching for a paddle, this stretch is a miss.
Now, after that long gap, things start to look a little more interesting. The standout window kicks off around the weekend of July 25th and 26th.
Saturday, July 25th is the real highlight. We’re talkin’ a proper SSW groundswell with a solid 7ft on the morning sets and a long period of 13 seconds. The combined swell energy is a powerful 1823, which is serious juice. That’s advanced territory for sure – too big for beginners – but for those with experience, the energy will be there. The wind will be light and from the W, holding mostly onshore, so it won’t be glassy, but the sheer size and power of that swell is undeniable, and the consistency looks good. Blacks Beach will be the place to be.
Sunday, July 26th will still have some solid size dropping to around 3ft, but check this out: the period jumps to 19 seconds. That’s proper long-period groundswell energy, and in that case, it’ll break with real power and shape. The combined swell energy is still a very strong 1285. The wind swings to a light SW, giving us a light cross-onshore breeze, with just small wind ripples on the surface. It won't be perfect, but it’s the best quality we’ve seen in days, and the long-period nature will help it hold together well on the reef.
So to cut the chase, there’s a long, quiet spell to start, but hang in there. Saturday the 25th is the biggest day, and Sunday the 26th is the cleanest. Don’t waste your energy on the flat week before 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.
