Alright folks, Rusty here with a look at the next couple of weeks. We’ve got one spot on the radar, and it’s a steady little performer.
Let’s talk about Nine Mile Reef. This is a classic beginner-friendly reef set-up that’s fairly consistent, exposed to the swell, and loves a good SSE direction. The water’s sitting at 59.0°F, which is about average for this time of year, so nothing wild there.
We’re starting off Monday morning, July 6th, with a clean 3.9 ft SW swell and glassy conditions. The wind is dead calm, and the combined energy is a moderate 363. It’s not huge, but for a Monday morning session, it’s a real nice way to kick off the week. The afternoon stays glassy with a slight breeze, and the swell holds steady. That’s a solid day of small, clean waves.
Tuesday morning, July 7th, the swell bumps up a touch to 4.3 ft from the SW, period stretches to 12 seconds, and we’ve got a light cross-offshore breeze. The energy jumps to 543. This is clean, fun, and very surfable. Tuesday afternoon sees the swell hit 4.9 ft with a longer 13-second period, but a cross-on wind creeps in, making it a bit more marginal. Still, the morning is the clear winner.
Wednesday morning, July 8th, is a standout. Glassy conditions again, 4.6 ft of SW swell, and a 13-second period. The energy is a solid 958. This is the kind of morning you set an alarm for – smooth, clean, and with enough push to keep a beginner smiling all session.
Now, things get a bit heavy as we head into Thursday, July 9th. The swell jumps to 6.9 ft from the SSW, with a 14-second period. The wave energy is a powerful 1652. This is getting into expert territory. The wind is a moderate cross-onshore, which will chop things up, but more importantly, the size starts to become a problem for the break. Friday, July 10th, is similar – 7.2 ft swell and strong cross-onshore winds, making it a bit of a mess for a standard paddle session. Honestly, if you’ve got a kite, this setup might be more your speed than a surfboard.
The swell backs off through the weekend, but the wind stays messy. Saturday and Sunday are mostly cross-onshore and choppy, with some small, marginal waves. Not worth chasing.
We get a little reprieve on Monday, July 13th, with a clean 3.6 ft swell and a light cross-offshore breeze. A small, clean session for the patient surfer.
Looking further out, the middle of the week sees tiny waves. Tuesday, July 14th, has an afternoon glass-off with a 2.3 ft SW swell and a 12-second period – a longboard special. Wednesday, July 15th, is a small offshore morning with 1.3 ft of swell.
A slightly better pulse shows up on Friday, July 17th, with a moderate offshore wind and a 3.0 ft SW swell. It’s clean, but it’s a far cry from the early week action.
The long-range forecast has a bit of promise. On Sunday, July 19th, the swell starts to build again to 5.2 ft from the SW, but the wind is a light cross-onshore. And then Monday morning, July 20th, looks glassy again with a 4.3 ft SW swell. That’s a promising prospect for a dawn patrol.
And way out there, Tuesday, July 21st, the guidance shows a 6.2 ft SSW swell with a 12-second period. The energy is massive at 1432, but it’s going to be big and a bit messy. Something to keep an eye on, but not a sure thing this far out.
Overall, the best bet on offer is Wednesday morning, July 8th. Glassy, clean, 4.6 ft SW swell with good period. That’s your window. After that, we get a few smaller clean windows, but nothing with that same punch.
Stay stoked.

Information about the Nine Mile Reef Surf forecast
The above surf forecast table for Nine Mile Reef provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Nine Mile Reef can be found by selecting the local surf guide option on the grey menu. Our Nine Mile Reef 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 (Nine Mile Reef) 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 Nine Mile Reef 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.
Nine Mile Reef is 19 km (12 miles) from the very large city of Bellville. If you plan a holiday in Cape Town, look for hotels and other accommodation in Bellville. Bellville has rooms for a wide range of budgets as well as cheap car hire and transport links.
