Alright, Rusty here again, breaking down Black Rocks for you in feet and miles per hour.
Water temp is running a bit cooler than average at 58°, so you'll want a good wetsuit. The first real surf shows up Sunday the 6th of July. Monday afternoon is where it turns on. A 6ft WSW groundswell with an 11-second period, glassy offshore wind at 3 mph. Combined energy sits at 927 (moderate) – very good surf for the advanced crew only at this reef.
Tuesday the 7th of July morning brings a 6ft SW swell, 12-second period, clean with 953 energy (moderate). But Tuesday afternoon is the standout of the first week: a 7ft SW groundswell, 13-second period, 1493 energy (strong), with a light cross-off breeze. This is excellent for experienced surfers. Swell direction is right in the SE optimum for this break.
Wednesday the 8th of July morning is still solid with a 6ft SW and 1872 energy (strong) and offshore wind, but the afternoon gets hammered by a 19 mph cross-onshore wind. That's a kite session, not a paddle session.
From Wednesday afternoon through the weekend, it’s blown out junk. Onshore winds and messy conditions, despite energy readings over 2000 (strong).
The next real window is Saturday the 11th of July morning. Swell drops to 5ft from the SSW, but the wind goes glassy. Period is 12 seconds, energy at 1173 (strong). Perfect glass-off conditions for the experts. This is your second standout.
Monday the 13th of July offers a clean 4ft S groundswell, 13-second period, glassy. Only 436 energy (moderate) – a nice mellow session.
Wednesday the 15th of July has a 28-31 mph offshore wind. The 4-5ft SW swell looks okay, but that kind of wind makes paddling out extremely difficult. Experts only.
Thursday the 16th of July afternoon cleans up: a 4ft SW swell, 12 seconds, light cross-off, 1035 energy (strong) – very good.
The weekend of the 18th of July brings a huge 10ft WSW pulse with 3581 energy (very strong), but winds are cross-onshore and choppy. Big and ugly.
Monday the 20th of July ends the period with a 6ft WSW, 1048 energy (strong), and a cross-off wind. Marginal but possible.
Best bets: Monday afternoon the 6th and Saturday morning the 11th. First week has the quality; second week fights the wind.

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.
