Alright, Rusty here. Let’s have a look at what's cooking.

Right now, there’s nothing for a few days. The first real chance to get wet isn’t until Sunday afternoon, July 5th, and it’s not going to be pretty. We’ve got a solid 7ft SW swell rolling in at 15 seconds, but that south wind is blowing cross-on at 9 mph, making it choppy. The water sits at a warm 77°, which is about a degree and a half warmer than normal for this time of year – feels nice, but the surface is a mess.

Monday the 6th and Tuesday the 7th stay similar or get worse. Monday sees a bigger onshore wind, 15-19 mph, just turning it into a washing machine. A lot of chunky, messy energy in the water but completely unsurfable with that wind.

Things start to turn Wednesday the 8th. The morning goes glassy with a light ENE breeze, and we’ve still got a clean 5ft SW swell at 11 seconds. The wave energy is moderate, but the surface will be glassy and clean. It's not huge, but it's the first proper window. By Thursday the 9th, it drops right off to under 3ft – not worth paddling for.

Friday the 10th is still small, but the afternoon glass-off with a 3ft SW swell at 14 seconds looks pleasant enough for a longboard if you’re desperate.

The standout period is Saturday the 11th through Monday the 13th. This is where it gets good. Saturday morning, the 11th, kicks off with a glassy 5ft SW groundswell at 15 seconds, and by the afternoon it’s up to 6ft. Wave energy jumps solid. That’s proper. Black Rocks Jetty is a reef break, so that long-period swell will wrap in beautifully, offering clean, powerful lines. The water is glossy, the wind is zero or light – this is the best of the first week.

Sunday the 12th pushes into the 8ft to 8ft range, still glassy, still long-period SW swell. That gets heavy – that’s expert territory, over 8ft is only for the brave. But with the reef holding it together and no wind, it will be a proper session for those who can handle it.

Monday the 13th holds at 6ft in the morning with totally calm conditions – another one for the experienced crew.

After that, the second week tapers off. Tuesday the 14th and Wednesday the 15th have waist-chest high swell, mostly glassy mornings but some rain showers around. Nothing to shout about.

Now, look ahead to Sunday the 19th and Monday the 20th. There’s a big one brewing. Sunday afternoon the 19th sees a bizarre 22-second period swell from the SSW (5ft), but it’s blowing straight onshore. Not great. But Monday morning the 20th? That is the big daddy. A 10ft SSW groundswell at 17 seconds, with zero wind and glassy conditions. The energy is strong to very strong. That is an exceptional, powerful swell for experts only. The afternoon holds another 10ft with a light glass-off. It's two weeks out, so treat it with some caution, but if that holds, it’s the best on offer in the whole outlook.

Crowds at Black Rocks Jetty can be a problem sometimes, especially when it’s good. Plan your paddle-out after dark or very early if you want a peak to yourself.

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.
