The Lowdown

Alright, Rusty here. Let’s talk about what’s cooking at Black Rocks.

We’ve got a proper 16-day window ahead, but it’s a bit of a mixed bag. The first real action worth talking about kicks off on Friday, the 7th of August. The water is sitting at 58°, which is a bit colder than normal for this time of year, so don’t be shy with the wettie.

The standout session is easily Friday afternoon. We’ve got a solid 10ft SW groundswell rolling in with a period of 15 seconds – that’s a proper long-period groundswell, packing a ton of energy (3565). Best of all, the wind is WSW and offshore, making for clean, lined-up waves. This is a reef break for advanced surfers only, and it’s inconsistent, so you’ll be waiting for the sets, but when they come, they’ll be worth it. The swell is over 8ft, so this is experts-only territory.

Saturday morning, the 8th, is a decent second option. The swell drops to 8ft from the SW with a 13-second period, and we’ve got a cross-offshore wind from the NNW. The energy is still moderate (1810), and the waves will be clean. It’s a solid session, but not quite the magic of Friday afternoon.

After that, the conditions get ugly. From Saturday afternoon through to the end of the first week, the wind swings onshore or cross-shore with strong speeds, and the surf quality tanks. There’s a stretch of days – from the 8th to the 11th – where the recommendations are poor, and you’d be better off doing something else.

The next real glimmer comes on the morning of Saturday, the 15th of August. We see a 6ft WSW swell with a 15-second period, light cross-offshore wind from the NW, and clean conditions. The energy is moderate (1506), and the sets will have some punch. It’s a good morning for the experienced crew, but with the inconsistency, you’ll need patience.

Then, on the morning of Wednesday, the 19th of August, we get another chance. A 7ft WSW swell with a 12-second period, light cross-offshore wind from the NW, and clean conditions. The energy is moderate (1019), and the forecast says “expect very good surf conditions.” It’s a promising long-range call, but less certain this far out.

Overall, the best bet is Friday afternoon, 7th August – that’s the one to circle. The 15th and 19th are worth watching, but don’t hold your breath on the rest. The spot is inconsistent, so when it’s good, you’ve got to be there.

Rusty.

Information about the Black Rocks Surf forecast

The above surf forecast table for Black Rocks provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Black Rocks can be found by selecting the local surf guide option on the grey menu. Our Black Rocks 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 (Black Rocks) 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 Black Rocks 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.
