The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Black Rocks. This is a reef set-up that likes a good SW swell, and we’ve got a solid run of SSW energy rolling in. The water is sitting at 77°F – a touch warmer than normal for the time of year, which is a nice bonus.
The first real window opens up Tuesday afternoon, the 28th of July. The swell is 5ft from the SSW with a very long period of 18 seconds, and the combined energy is pumping at 2515. That’s powerful, long-period groundswell – perfect for a reef like this. The wind is light cross from the SE at 3 mph, so it’s clean with just a bit of texture. The tide might be a factor, but if you can line it up, there’ll be some proper waves. It’s a touch on the big side for beginners, but for intermediates, this is a solid session.
Wednesday the 29th of July is the standout. The morning brings 7ft of SSW swell, period at 14 seconds and energy at 2061. Wind is light cross-off from the E at 6 mph – clean, well-shaped lines. Then in the afternoon it goes glassy with the SSE breeze dropping to 3 mph, swell dropping slightly to 7ft but still with that 14-second period and 1619 energy. This is the best on offer. For experienced surfers, this is a dream. The reef will handle that long-period energy beautifully, and the lack of wind will make it look like a postcard. Be aware, crowds are possible here, so get out early.
Thursday the 30th of July is worth a mention too. Afternoon glassy conditions again with the E wind at 3 mph, swell 4ft from the SSW, 13-second period, energy at 1091. It’s smaller, but still very clean and fun for a longboard or a fish.
Friday the 31st of July holds strong. Morning rain showers, but cross-off wind from the ENE at 9 mph, with 6ft of SSW swell and a 16-second period, energy at 1441. The afternoon turns offshore from the NE at 6 mph, same swell. Clean, powerful, and lined up. This is another top-tier session.
Saturday the 1st of August and Sunday the 2nd of August see the swell holding around 5ft to 6ft from the SSW, with periods between 14 and 16 seconds. The wind is cross-off from the E or ENE at 9 to 12 mph. The energy stays high (up to 1566), but the breeze picks up a bit, so it’s not as perfect as Wednesday. Still very surfable, especially for the more experienced crew.
Things start to fade from Monday the 3rd of August. The swell drops to 4ft, then 3ft by Tuesday the 4th, and the wind gets stronger from the E at 15 to 18 mph. The energy drops into the hundreds (428, 325). The quality goes with it. This is a quiet patch.
Then on Wednesday the 5th of August, a fresh pulse arrives. The swell jumps back to 5ft to 6ft from the SSW, with an 18-second period and energy climbing to 1804. But the wind is a fresh cross-off from the E at 15 to 18 mph, so it’s lumpy and not as clean. Still, there’s power in the water – more for the charger than the casual surfer.
The second week is a bit of a mixed bag. Thursday the 6th of August sees 5ft at 14 seconds, but fresh breeze at 18 mph. Friday the 7th of August is poor, with onshore winds and lumpy conditions. Saturday the 8th of August offers a slight improvement, with 4ft and a 17-second period, but still a strong cross-off breeze. Sunday the 9th of August shows a better-looking pulse of 6ft at 16 seconds, energy at 1391, but the wind is still moderate.
The real late highlight is Tuesday the 11th of August. The swell jumps to 6ft to 6ft from the SSW, with a very long period of 18 seconds and energy at 2439. That’s a serious amount of water moving. The wind is cross from the SE at 12 to 15 mph, creating a cross-chop, so it won’t be perfect. This is a powerful, tricky session for experts only. The reef will handle the long period, but the chop will make it a battle.
All in all, the clear winner is Wednesday the 29th of July. Glassy, clean, and solid. If you miss that, Friday the 31st of July is a close second. The long-range stuff on the 11th of August is promising, but with the wind and the chop, it’s less certain.
Stay safe, and score that glassy morning.

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.
