The Lowdown

Alright, surfers, Rusty here. Let's get into it. We've got a 16-day window, and honestly, it's a bit of a mixed bag. The first few days offer some decent waves, but a long quiet spell follows before a possible late flurry.

The standout option is Black Rocks. This is a reef break, and it's inconsistent, so you gotta pick your moments. The water temperature is running at 77°, which is a touch warmer than normal for this time of year.

We kick off on Friday the 31st of July. The morning sees a clean 6ft SSW swell with a very long 16-second period. That's proper groundswell energy, and the cross-off wind from the East at 9 mph is keeping it clean. The combined energy is strong at 1305. This is your best bet for the start of the period. The afternoon holds similar lines, with a 5ft SSW swell and the same clean conditions.

Saturday the 1st of August keeps the run going. Morning brings a 6ft SSW swell, again with a long 15-second period and cross-off wind. It's a touch bigger, but still clean. The afternoon sees some rain showers, but the swell holds at 6ft.

Sunday the 2nd of August, the swell dips a bit to 6ft in the morning, with the wind picking up to 16 mph from the East. It's still cross-off, so it's rideable, but the wind is stronger. The afternoon pushes 19 mph, which is getting a bit lumpy for a clean line.

From Monday the 3rd of August, the swell really drops off. By Monday morning, we're down to 3ft, and it just fades from there. The wind stays strong from the East, making for poor surfing conditions. The period from the 4th of August right through to the 11th of August is basically a write-off. For nearly a week, the swell is below 3ft, and the wind is a cross-shore mess. The combined energy drops to a weak 258 on the 6th. It's a long, flat gap.

Then, around the 12th of August, the swell tries to build back. We see a 6ft SSW swell on the morning of the 12th, but the wind is a stiff cross-shore from the SE at 16 mph, which chops it up. The energy is strong at 1624, but the quality is poor.

The real promise lands on the 15th of August. That Saturday morning, we have a clean 4ft SSW swell with a 16-second period, and a cross-off wind from the ENE at 9 mph. The combined energy is a solid 1046. But it's the afternoon that gets the blood pumping. The wind swings to the NNE at 9 mph, turning offshore. It's a 4ft SSW groundswell, clean and glassy. The energy jumps to 1306. This is the standout window further out. It's a promise, so keep an eye on it.

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.
