The Lowdown
Alright, talkin' waves here at Black Rocks. It's a reef, and it's looking like we're in for a proper waiting game. Water temp's about normal for this time of year.
The first week is gonna be a bummer, plain and simple. There's a bit of pulse this weekend, but the tide's all wrong and the waves are gonna be a mess. Then it totally flat-lines for a good five days mid-week. You'll be staring at flat, glassy water and there's nothing to do but wax your board and dream.
Now, things get interesting toward the end of the month. The standout is that Sunday, the 23rd. Big, powerful swell rolls in – we're talking 12ft from the SSW with a 16-second groundswell, and the energy is off the charts at (7173). The wind is clean and offshore, so the reef should be firing. That's a wave for the hardcore guys only – over 8ft and packing a punch.
That size sticks around for a few days, but the wind goes all wonky, blowing cross-shore and making things choppy. The 28th looks like another good day – back to that clean offshore wind with the swell still holding strong at 12ft. It fades out after that, getting messy and smaller into the 31st. So yeah, if you're an expert, circle the 23rd and the 28th. Everyone else, maybe find a lake.

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.
