The Lowdown
Hey, Rusty here. Black Rocks Jetty is looking at a solid stretch of surf for those who know what they’re doing. Water temp’s about 77°, a bit warmer than usual—feels good.
Saturday morning the 22nd starts clean: 5ft SW groundswell, 14 seconds, glassy with light north wind. Combined energy’s moderate at 901. That long period works well on the reef. Crowds can show up sometimes, but it’s worth it. Afternoon’s similar.
Sunday the 23rd, it gets real: 8ft SW, 14 seconds, glassy. Energy’s up to 2155. This is for advanced surfers only. 8ft on a reef with that period is no joke. Afternoon holds at 7ft.
Monday the 24th is the pick of the first week. Calm, glassy morning, 7ft SSW groundswell at 15 seconds. Energy’s 2452—strong and clean. Long period gives organised sets and easy paddling. For experienced surfers, this is it. Afternoon stays solid.
Tuesday the 25th backs off to 6ft to 5ft, still clean. Wednesday the 26th drops to 4ft to 3ft, but that afternoon has an 18-second period for some glide.
Thursday the 27th goes big and messy: 8ft to 10ft SSW with onshore wind—choppy. Friday the 28th is huge: 15ft to 13ft, energy over 10,000, but cross-shore wind and chop make this for big-wave folks or kite surfers.
Saturday the 29th is the standout for the second week. Morning brings 12ft SSW groundswell, 16 seconds, glassy. Energy at 6290—strong to very strong. Exceptional, expert-only. Afternoon drops to 10ft but still glassy and calm.
Sunday the 30th is back to 7ft, clean. Monday the 31st fades to 4ft. Then from the 1st to the 4th of September, it’s flat—tiny swell, poor conditions. Energy drops to as low as 84, with waves from 1ft to 3ft and cross-onshore breeze. About four days of nothing, normal for here.
The 5th of September perks up: 4ft SW groundswell with a very long 20-second period, glassy morning. Energy at 1504. The 6th of September morning has 5ft at 16 seconds with cross-onshore wind; afternoon turns glassy again with 5ft.
Best wave? Monday the 24th for size and glass, and Saturday the 29th for the big, heavy session.
Rusty.

Information about the Black Rocks Jetty Surf forecast
The above surf forecast table for Black Rocks Jetty 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 Jetty can be found by selecting the local surf guide option on the grey menu. Our Black Rocks Jetty 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 Jetty) 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 Jetty 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.
