Table - best surf conditions forecast for Black Rocks over the next 16 days.


Alright folks, Rusty here. Let's have a look at what's on the cards for this stretch of coast.

The coming week has a bit of a mixed bag, but there’s a clear standout early on and then a long, frustrating spell of junky conditions. The real magic happens on Monday the 13th and Tuesday the 14th, so you’ll want to be on it.

The main event is Black Rocks. This exposed reef break is an intermediate zone, and it's inconsistent so it doesn't fire all the time – but when it does, it's special. The water is sitting at 77°F, a touch warmer than usual for this time of year, which is a nice little bonus.

Monday the 13th is the absolute pick of the entire 16-day window. The mornings are looking clean with a light cross-offshore breeze from the NE. We’ve got a solid 7ft SSW groundswell with a long 14-second period, which is perfect for a reef setup like this. The combined energy is massive (1667), so there’s serious power moving through. The afternoon holds up just as well with the same size and shape. This is excellent, powerful surf for experienced surfers.

Tuesday the 14th is still a solid option. The swell drops a touch to 6ft, still from the SSW with that lovely long period, and the wind stays clean out of the east. It’s a little smaller, but still quality. The energy is still pumping (1143).

Now, after that, it gets ugly. We have a massive gap of poor to marginal conditions. Wednesday the 15th starts to wind down, and by Thursday the 16th it’s under 3ft and ordinary. A brief, fun moment arrives on Friday the 17th morning with a glassy 2ft swell, but it's tiny. The real story from the 18th of July onwards is a relentless run of strong cross and cross-onshore winds out of the south and southeast, often with a fresh breeze. The swell actually gets quite big again with an 8ft SSW swell on the 20th and 21st, but it's completely blown out and choppy. That combo of big swell and bad wind makes it a write-off for a paddle board. With conditions like that on a reef, you’d honestly be better off with a kite.

This poor run of wind and lumpy conditions looks set to continue right through to the end of the forecast on the 28th. There’s a spike of 10ft on the 28th, but it’s short-period and cross-shore wind. It’s a hard pass for the second week unless you’re desperate for a paddle in messy, lumpy lines.

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.
