The Lowdown

Alright folks, Rusty here. Let’s break down what’s in store for Kanaha over the next couple of weeks.

Right off the bat, it’s a slow burner. From Wednesday, the 26th, all the way through the first week of September, the surf is there but it’s not really firing. The wind is a steady cross-off or cross breeze most of the time, which keeps the surface looking clean, but the swell is short-period and the energy is just average. The combined energy readings are mostly in the 150 to 350 range, so it’s moderate at best. You’ll see waves from 4ft to 5ft out of the ENE, but with a period of just 6 to 8 seconds, it’s going to be a bit weak and messy. Honestly, the conditions are labelled as marginal or poor all through that first week, so don’t get your hopes up.

The real bright spot comes around Thursday, the 3rd of September. The quality finally starts to look up. The swell is still around 5ft from the ENE, but the period improves a little, and the wind stays light and cross-off. The combined energy bumps up to 389, which is moderate but feels more powerful. The real standout, though, is the 5th of September. On Saturday morning, we’ve got a 5ft ENE groundswell with a period of 10 seconds, light cross-off winds, and a combined energy reading of 444. That’s the best-looking window in the whole run. The water temperature is sitting at 80°F, which is pretty much normal for the time of year, so you’ll be fine in boardshorts.

Now, a word on Kanaha. It’s a reef break, exposed to the NNE, and it’s fairly consistent. The crowds are a factor here – they show up sometimes, so you’ll likely have company. The swell direction is ENE, which is a good angle for the spot. The 5th of September is the one to circle on the calendar. It’s the best balance of size, period, and wind we’ve got.

After that, the surf tails off again. The 6th of September has a brief spike in energy (536 in the morning), but the swell drops to 4ft and the period gets shorter. The second week looks patchy, with more rain showers and a stronger ENE breeze picking up around the 8th. The swell drops further, down to 3ft by the 9th, and the energy falls off. It’s not looking great for a solid session then.

Overall, the best bet is the morning of the 5th of September. For the rest of the run, it’s a bit of a waiting game, but the forecasts can always change for the better.

Rusty out.

Information about the Kanaha Surf forecast

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