The Lowdown
Alright, Rusty here, let's have a look at what's on the table for the next couple of weeks.
Alright, first up, we've got a bit of a wait on our hands. The surf that's coming in is a bit of a mixed bag, and the first real standout is a few days out. The main event is Nine Mile Reef, an exposed reef break that's a beginner-friendly spot when the conditions line up. The water is sitting at 60°F, which is pretty much spot on for this time of year, so no surprises there.
The first real action is on Friday, 24th July. It's a big one, but it's a bit of a double-edged sword. The morning is glassy, with a 8ft SSW swell at a super long 15 seconds. The combined energy is massive (2371), and it's a very long period groundswell. This is a lot of power for a reef, and it's actually forecast to be too big for this break, so this is for the brave and experienced only. The wind is dead calm, so it'll be clean, but that's a lot of water moving around. The afternoon drops a little to 7ft, but the wind swings onshore, so the quality will drop off.
Saturday, 25th July is a step down, but not in a good way. The swell drops to 6ft, but the wind is a messy cross-onshore, making for a lumpy surface. The energy is still decent (1508), but the conditions are marginal. It's a write-off for a good session.
Sunday, 26th July morning is the first real bright spot. We've got a 5ft SW swell with a good 11-second period, and the wind is glassy. The combined energy is moderate (727). This is a nice, clean, manageable size for a beginner spot, and it'll be a fun, mellow session. The afternoon gets a bit onshore again, so get it early.
Monday, 27th July through Tuesday, 28th July is a complete mess. The swell is up around 6ft to 7ft, but the wind is a strong, choppy cross-onshore from the SE and ESE. The energy is high (over 2000), but the surface is a wind-blown disaster. Don't bother.
Wednesday, 29th July morning is another glassy winner. The swell drops to 4ft, but it's clean and glassy with a 13-second period. The energy is moderate (945). It's a small, clean wave perfect for a longboard or a fun cruiser. The afternoon stays glassy but drops a little more.
Thursday, 30th July morning is glassy again, but the swell is small at 3ft. The energy is low (254). It's a tiny, clean wave, only really for the foamy or the absolute beginner.
Friday, 31st July is the real standout of the entire forecast. The morning is glassy, and we've got a 6ft SSW swell with a very long 16-second period. The combined energy is huge (2327). This is a proper groundswell, and for a reef, that's a beautiful thing. It's a solid, powerful, clean wave. The forecast says it's excellent for experienced surfers, and that's exactly what it is. The afternoon gets a bit onshore, so the morning is the window.
Saturday, 1st August morning is glassy again with a 5ft SSW swell. The energy is moderate (872). It's a nice, clean, smaller version of the day before. A great follow-up session.
The rest of the first week into the second week is a bit average. The swell drops and the wind is mostly onshore through to Monday, 3rd August, when we get a glassy morning with a 5ft SW swell for another clean session. After that, it's a mix of onshore wind and marginal conditions until Thursday, 6th August. That morning is absolutely glassy again, but we're back to a 8ft swell with a 12-second period. The energy is high (2184), and it's forecast to be too big for the break again. It's a big, clean set, but it's a lot of power.
The Friday, 7th August gets a mention for the wind. The morning has a moderate offshore wind from the N, which is rare and will make for some clean, lined-up waves on a 4ft SW swell. The afternoon is clean too. It's a small day, but it will be tidy.
The final shout is for Saturday, 8th August, but it's an onshore mess with a 7ft swell. Too big and too windy for a good time.
So, the best on offer is without a doubt the Friday, 31st July morning at Nine Mile Reef. It's a powerful, glassy, long-period groundswell that will be an absolute treat for anyone who can handle it. The second best is the Sunday, 26th July morning for a cleaner, smaller, more relaxed session.

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.
