The Lowdown
Hey, Rusty here again, breakin’ it down in feet and miles per hour for ya.
First few days are a bit of a bust at Black Rocks. There’s some size on Sunday morning with waves around 8 feet from the south, but the wind is screaming out of the east-southeast at 25 mph, turning it into a messy, lumpy cross-chop. Not great for a paddle, but with that much wind and that size, it’s gonna look more fun for the kite crew than us. The combined wave energy is a strong 3023, but it’s just not clean.
The wind backs off by Tuesday and Wednesday, but the swell crashes down to almost nothing—1 to 3 feet. Water temp is sitting at 76°, which is a touch warmer than normal for this time of year.
Now, mark the 6th of September on your phone. That’s Sunday. The morning looks like a total sleeper hit. Swell is a modest 4 feet from the south-southwest, but the wind goes absolutely glass. Zero. Dead calm. Clean as a mirror. Black Rocks is an inconsistent reef, so catching it in a zero-wind window is a gift. The combined energy is moderate at 595, but with a 13-second period, that’s proper groundswell. This is your quiet, clean standout for the first week.
After that, we get a small spike around the 7th with 5-6 foot waves, but the wind turns cross-onshore, so the quality is cooked.
The real heavy hitters start on the 9th of September. Wednesday pumps up to 11-12 feet from the south-southwest, with a massive combined energy of 8555. That’s strong, serious energy. But the wind is still a fresh cross-shore at 19 mph, so it’s gonna be a lumpy, churning beast. Experts only.
The absolute best shot of the whole 16 days? That’s the morning of Monday, the 14th of September. Swell is a solid 7-8 feet from the south-southwest, with a super long 18-second period. The wind is light and offshore from the east at just 6 mph. That’s strong groundswell energy (3140) with clean, offshore conditions on a reef that loves that south-west direction. It’s a long way out, so don’t lock it in just yet, but the recipe looks perfect. That’s the one.
Stay stoked,
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.
Black Rocks is 12 km (7 miles) from the city of Vacoas. If you plan a holiday in Mauritius, look for hotels and other accommodation in Vacoas. Vacoas has rooms for a wide range of budgets as well as car hire and transport links.
