The Lowdown
Alright, I gotta be straight with you. The first few days here are a write-off. We’re looking at a pretty grim start with no real surf on offer from Saturday the 15th right through Monday the 17th. The wind is just awful, cross-shore and strong, turning the waves into a mess of lumpy chop. It’s just not worth paddling out.
But there is a light at the end of the tunnel, and it’s a beautiful one. The real standout window is Tuesday the 18th. This is the one to circle. The morning at Salamumu kicks off with a clean 5ft swell out of the SW, with a light cross-offshore breeze. The energy is building nicely, and by the afternoon, it gets even better. The wind goes glassy, the swell bumps up to 5ft from the same SW direction, and the energy gets solid. The water temp is sitting at 80°, which is about average for this time of year. This is top-tier stuff for anyone who’s comfortable on a reef break. The period is a long 16 seconds, so expect proper groundswell lines with good shape and power. You’ll get clean faces and long, open walls. It is a consistent, exposed reef, so it’s for those with some experience.
After that, the wind turns on us again. Wednesday the 19th and Thursday the 20th look write-offs with strong cross-onshore winds and messy, lumpy conditions. The swell hangs around, but the quality is just not there. This pattern of poor conditions kicks on for a solid week, all the way through to the 26th. The wind is relentless from the SE and ESE, just tearing the surface up.
Then, there’s a second, more distant promise. Thursday the 27th of August is looking like another cracker. The afternoon session is the pick: a clean 5ft SW swell with a 17-second period, and the wind is offshore at 9 mph. That’s a recipe for perfection. The energy is very strong, and it’ll be glassy, clean, and powerful. It’s a bit far out, so keep your fingers crossed, but it has the potential to be just as good as Tuesday the 18th. The 28th is a bit more marginal, but the 27th is the real second highlight.
So, to sum it up: the first few days are a washout. The best bet is Tuesday the 18th, full stop. Keep an eye on the 27th of August for a possible repeat performance.

Information about the Salamumu Surf forecast
The above surf forecast table for Salamumu provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Salamumu can be found by selecting the local surf guide option on the grey menu. Our Salamumu 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 (Salamumu) 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 Salamumu 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.
