Alright folks, Rusty here. Let’s have a look at the 16-day picture for Nine Mile Reef. It’s a reef setup, fairly consistent, good for beginners normally, and it likes swell from the SSE. Right now the water's sitting at about 59°, which is a bit colder than normal for this time of year – not crazy, but you'll notice it.

We’ve got no decent surf to start. The first real window of clean waves shows up on Monday morning, July 6th. The wind is glassy with a light breeze from the SE, and we're looking at a solid 4 ft swell from the SW with a decent 12-second period. The combined energy is strong (492). This is a good one for a relaxed session – clean, glassy, and the swell direction is wrong for optimum but the quality looks good.

The best of the whole run, without a doubt, is Tuesday morning, July 7th. Dead calm wind, glassy conditions, and a clean 5 ft SW groundswell hanging in there at 12 seconds. The combined energy is up there (585). This is that window where everything lines up – offshore wind, clean faces, and a swell that’s just right for this reef. Get out there early.

From Wednesday July 8th through the rest of the first week, the swell builds fast but the wind turns onshore and the waves get lumpy. By Thursday July 9th, we're seeing 6 ft of SSW swell with cross-onshore winds, and the energy is very high (1740) but the quality is cooked. It stays messy until Saturday July 11th when the wind goes light offshore again from the NNW. The swell drops back to 5 ft from the SSW (741 combined energy) and conditions should be very good. That’s a solid backup day.

Sunday July 12th is a write-off – short period, sloppy cross-on winds, poor surf. Monday July 13th is tiny and glassy but only about 3 ft – small and ordinary. Tuesday July 14th brings a cleaner 2 ft SW groundswell in the morning (264 energy), but the afternoon turns choppy.

Now, into the second week, things get real big. From Wednesday July 15th through to Saturday July 18th, the swell pumps up to 8 ft to 10 ft from the SW and S directions. The combined energy hits four-digit numbers – massive, powerful swell. Problem is, these waves are way too big for beginners and borderline even for experienced surfers here. The wind does go glassy on the morning of Thursday July 16th and Friday July 17th, but with 10 ft plus on the cards, it’s for experts only. Saturday July 18th eases back to about 8 ft with a cross-off breeze – still heavy, but cleaner. If you're a seasoned charger, that Saturday morning session could be the standout of the second week, but for the average surfer, it’s a watch-and-wait situation.

Overall, the first Tuesday is your golden ticket. The second week has size and power, but only for the brave.

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.
