Updates in hr min s Forecast update imminent
Alright folks, Rusty here, giving you the long-range outlook for Nine Mile Reef. We’ve got a bit of a story unfolding over the next couple of weeks, so let’s get into it.
The water is sitting at 59°, which is a bit colder than what you’d normally expect for this time of year. Nothing crazy, but worth having that extra rubber on hand.
Right out of the gate, the first few days are a bit flat and weak. Saturday and Sunday have some small waves, but honestly, with a weak swell energy of 182, not much to get excited about. The real story starts to build as we push into the new week.
Monday, July 6th is where things start to look interesting. The morning is a standout. We’ve got a glassy clean 4ft SW swell rolling in, and the energy is picking up to 417. It’s the best of the bunch for the early part of the forecast. The wind is dead calm – glassy, clean conditions. This is the one to target if you’re looking for a proper session.
Tuesday morning, July 7th, is also quality. Another 4ft of SW swell, with 526 of energy, and a light NNW offshore wind. The conditions will be clean and lined up nicely.
Wednesday and Thursday look like a write-off. The wind swings onshore and choppy, and the swell gets a bit jumbled. Leave those days for something else.
Then Saturday, July 11th rolls around. This is another standout window. The morning session is looking very good. We’ve got 4ft of SSW swell, the wind is glassy from the ESE, and the energy is a solid 586. It’s clean, manageable, and well worth a paddle out.
After that, the forecast gets a bit dicey again. There’s a period of smaller, ordinary surf through Monday, July 13th. Not a total loss, but nothing to set an alarm for.
We then see a big spike in size around Wednesday, July 15th, with a 6ft S swell. But the period is a short 8 seconds, so it’ll be a bit lumpy and won’t have that same punch. By Thursday, July 16th, we’re looking at a 10ft swell from the SSE. That’s expert-only territory at Nine Mile Reef – too big for most of us. Friday and Saturday also hold onto some size but the onshore winds and rain make for poor, messy conditions.
Sunday, July 19th brings a little relief. A cleaner 4ft SSE swell with a light offshore wind from the north. It’s a nice way to wrap up the outlook, with solid energy at 392. It’s a good, surfable option.
So, to sum it up: Look hard at Monday morning, July 6th, and Saturday morning, July 11th. Those are your true standouts. Everything else is either too small, too big, or too windy. The middle of the second week gets heavy, so keep that in mind if you’re a beginner.
Rusty.

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.
