G'day, Rusty here.

Alright, we've got one spot on the radar for the next couple of weeks – Black Rocks Jetty. It’s a reef break, so it handles a bit of size, but it’s strictly for the advanced crew. The water’s sitting at 77°, which is a touch warmer than usual for this time of year – you’ll notice it straight away.

We kick things off this Monday afternoon, July 6th, but it’s a write-off with a 16 mph cross-on wind and a messy 6ft SW swell. The energy’s solid (1591), but it’s gonna be choppy and poor. Tuesday morning (July 7th) is still a bit marginal with a 6ft S swell and cross-shore wind. The real action starts Tuesday afternoon, July 7th – the swell jumps to 10ft from the S, pushing strong energy (3862). That’s big, powerful stuff, expert-only territory. The wind stays cross-shore, so it won’t be perfect, but for experienced surfers, that’s a solid window.

Wednesday, July 8th, is a gem. We’ve got clean glassy conditions in the morning with a 5ft S swell, and it stays glassy in the afternoon with a 5ft S swell. The energy’s moderate (639 and 529), but the total lack of wind makes it a true standout – perfect, clean lines on the reef. Thursday (July 9th) keeps the glassy run going but the swell drops back to 3ft and 3ft, so it’s smaller but still fun.

Friday, July 10th, is another standout. Glassy conditions all day, with a 3ft SW swell in the morning (388 energy) and a 4ft SW swell in the afternoon (543). That afternoon session with the 14-second period is going to have some real push and shape – a classic reefie pulse.

Saturday, July 11th, the wind turns light cross, and the swell holds at 5ft to 6ft from the SW. It’s a bit bumpy, but the long 14-15 second periods mean there’s plenty of grunt. A decent day if you don’t mind a little texture.

Then we get a run of superb conditions. Sunday, July 12th, through Monday, July 13th, the swell sits around 7ft to 6ft from the SW, with glassy mornings and excellent, powerful waves. That Sunday morning 7ft SW groundswell (15-second period, 2117 energy) is a heavyweight – heavy, clean, and only for experts. It’s gonna be a proper session.

From Tuesday, July 14th, things settle. We’ve got glassy mornings and clean 5ft to 4ft SW swell – very surfable. Wednesday the 15th is clean but small at 3ft. Thursday morning, July 16th, sees a spike in period to 16 seconds from the S, with 4ft and glassy conditions – that’s gonna produce some long, lined-up waves. A real highlight in the second week.

Friday the 17th and Saturday the 18th stay small and glassy in the mornings, with 3ft to 4ft SSW swell. Sunday the 19th is a write-off – tiny and cross-on. But then Monday July 20th brings another pulse: a 7ft S swell (1912 energy) with glassy conditions. That’s a proper morning for the experienced crew.

Tuesday July 21st winds down with a clean 4ft SSW swell in the morning. A solid finish.

The standout windows are Tuesday afternoon July 7th for the big 10ft power session, and the glassy, long-period pulses on Thursday July 16th and Monday July 20th. Don’t sleep on Friday July 10th afternoon – that’s clean and punchy.

This is a reef break, so expect it to get crowded – “sometimes” is what the book says, so be ready to share. Overall, there’s plenty of action across the fortnight.

Catch ya in the water.
Rusty

Information about the Black Rocks Jetty Surf forecast

The above surf forecast table for Black Rocks Jetty 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 Jetty can be found by selecting the local surf guide option on the grey menu. Our Black Rocks Jetty 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 Jetty) 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 Jetty 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 Jetty is 6 km (4 miles) from Saint-Paul. If you plan a holiday in Réunion Island, look for hotels and other accommodation in Saint-Paul. Saint-Paul has rooms for a wide range of budgets as well as car hire and transport links.
