Alright, grab your board, let’s see what we’ve got. This is Rusty.

For the next few days, the island’s only real focus is Black Rocks, a reef setup that takes a bit of patience but can deliver. The water temp is your typical winter reading, about average for the time of year, nothing too wild.

We’ve got a bit of a slow start, but the best windows are clear. Saturday the 4th is the standout: morning sees a clean 6 ft SSW swell with light easterly cross-off winds. The energy is solid but not enormous (979), and those 14-second intervals mean proper groundswell lines wrapping in. By afternoon it goes glassy with 5 km/h easterly breezes, waves drop slightly to 5 ft but the conditions are absolute perfection. This is your session.

Sunday the 5th is still rideable but not as clean. Morning has a smaller 4 ft SSW swell with cross winds, and the afternoon gets a bit bumpy as the wind swings south. It’s marginal.

Monday the 6th through Tuesday the 8th we get hammered. South winds hit hard, 30-40 km/h, and the swell jumps up to 10 ft on Tuesday. Combined energy hits 3333 – strong stuff. This is only for the most experienced, and even then, the conditions are poor. Honestly, looks more like a kite day unless you’re a masochist.

A pulse of cleaner long-period groundswell arrives Thursday the 10th. Friday afternoon the 10th is a real gem: 3 ft SSW swell, 18-second intervals, and glassy conditions with zero wind. Energy is moderate (756), but those long lines off a reef? That’s a sneaky good session. Keep that one on the radar.

The following weekend into the second week sees a big lumpy SSW swell pulse. Saturday the 11th and Sunday the 12th have 7 ft to 10 ft SSW swell, but cross winds and onshore tendencies keep things messy. Combined energy is high – over 3400 on Sunday. More a big-wave zone for experts only, and the tide might mess with it.

Wednesday the 15th brings a return to cleaner conditions. Morning has a small 3 ft SSW groundswell with 16-second periods and offshore winds. By afternoon it’s 4 ft and still clean. That’s worth the paddle.

Thursday the 16th afternoon glass-off is another little sleeper: 5 ft SSW, 13-second period, no wind. Very good conditions.

After that, the wind picks up and the quality drops off toward the 19th. Swell fades to under 3 ft with short periods and strong winds. Not worth chasing.

Best on offer: Saturday 4th – especially the glassy afternoon, and Friday 10th afternoon for those long period gems.

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.
