The Lowdown

Alright, Rusty here, let’s talk about what’s coming up over the next couple of weeks.

We’re starting this Saturday the 25th of July at Black Rocks, a reef break that’s fairly open to the swell. The water is 77°, a bit warmer than average for this time of year – you’ll feel it. That first morning we’ve got clean 4ft SSW swell with a 13-second period, light NNE wind off the shoulder. The combined energy is moderate at 686. It’s not big, but the wave can be inconsistent here, so you gotta time it right. Crowds are often. Saturday afternoon the wind goes light NNW, cross-off, and the swell bumps to 4ft at 14 seconds – still very clean.

Sunday morning the 26th is glassy with some cloud, light WNW offshore, and a smaller 3ft SSW swell, period still a nice 13 seconds. Energy drops a bit but the glass makes for a fun little session. Sunday afternoon the wind turns west, cross-on, and quality fades.

Now Monday the 27th – this is the one. Early morning, dead calm, glassy, and we’ve got a solid 8ft SW groundswell at 16 seconds. The combined energy is way up at 2923 – that’s strong. This is a big, powerful wave for experienced surfers only. Long lulls between sets, but on a reef like Black Rocks, the shape will be excellent. The afternoon stays glassy with the same size.

Tuesday the 28th and Wednesday the 29th keep that energy flowing with 5ft to 7ft SSW swells, clean cross-off east winds, and periods between 14 and 18 seconds. Energy stays well into the thousands. Prime mid-week.

Thursday the 30th drops to around 4-5ft, still clean cross-off, but quality gets more marginal. Friday the 31st picks up a little – 5-6ft SSW at 15 seconds, clean again. Worth a paddle.

Through the first few days of August, the pattern holds with clean 5-6ft SSW swells, but the wind starts to build from the east, and conditions become more marginal. Sunday the 2nd has rain showers and a 25 km/h cross-off breeze, so it’s not as clean.

From Tuesday the 4th onward, the wind turns more cross-shore and builds, quality drops. By Thursday the 6th, it’s a fresh 30 km/h cross-breeze with lumpy chop. Friday the 7th through Sunday the 9th is a write-off – strong cross winds, messy conditions, poor surf. Swell is tiny, barely 2ft to 4ft.

So the standout is Monday the 27th – that 8ft SW groundswell with glassy conditions and a long period is the one for experienced surfers. Tuesday and Wednesday are also excellent. After that, it fades into wind-affected surf, and the last few days are not worth it unless you’re kite-surfing.

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.
