The Lowdown

Alright, Rusty here, let’s talk in feet and miles per hour now.

The real highlight of this whole 16-day window is right at the start. Wednesday, September 9th, that’s the one to circle. We’ve got a clean 3ft SSW groundswell pushing in with a solid 14-second period, and the wind is glassy in the morning. That’s about as good as it gets for a reef setup like this. The combined swell energy is a solid moderate 631, and with the swell coming from the SSW which is right in the optimum direction for this spot, the waves will have proper shape and power. It’s an advanced wave, so it’s not for the faint of heart, but for those who can handle it, this is the standout. Water temperature is about average for this time of year, nothing unusual.

Come Wednesday afternoon, the wind shifts to a light cross-off, still clean, still 3ft, and the period drops a touch to 13 seconds. It’s still very good, just not quite as perfect as the morning glass.

Thursday the 10th, the swell switches to a short-period 5ft ENE windswell at only 7 seconds. The wind is up to 12-18 mph from the ENE, cross-off, but the poor period and choppy energy make this a write-off. The combined energy drops, and the surf quality is poor. That trend continues into Friday and Saturday: small, weak, short-period slop with wind keeping it ordinary. The swell energy drops to 222 or less, and the waves are inconsistent.

There’s a long gap after Saturday afternoon. Sunday through to the following Tuesday, the swell is tiny, under 3ft, and while the period gets long again (15-23 seconds), there’s just not enough size to work with. The energy is weak, most days under 300. This is a dead stretch.

Then around Wednesday, September 16th, the swell bumps up to 3ft from the SSW with an 18-second period, and the combined energy jumps to 762. That’s a moderate energy, but the wind is blowing 12-22 mph from the ENE, making it messy. It’s a tease, but the wind ruins it.

The rest of the second week, from September 17th onward, is not worth your time. The swell is mostly short-period ENE windswell, often over 5ft but with terrible 7-8 second periods, 15-25 mph winds, and poor surf quality. The energy jumps to 1199 on the 18th, but it’s a strong, lumpy, wind-affected mess. You’d need a really forgiving board and low expectations. The crowd factor at Tennis Courts is "sometimes", so on a good day it’s not a zoo, but on this run, you won’t have to worry about anyone else.

The real standout is without a doubt Wednesday, September 9th morning. Get on it.

Rusty.

Information about the Tennis Courts Surf forecast

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