The Lowdown
Alright, Rusty here, giving you the straight talk on Tennis Courts for the next 16 days. Let’s be honest, it’s not a dream run.
We’ve got swell coming in from the get-go, and the first week has some size to it. But the real story, unfortunately, is the wind. It’s locked in from the ENE at a fresh 19 to 28 mph for most of that time, blowing cross-offshore. The waves are running 7 ft to 8 ft, with a short, weak 8-second period. The combined energy starts moderate (743), then builds to strong (1270) and very strong (1692) by Friday the 4th of September. It’s powerful, but with that much wind on a short-period swell, it’s going to be choppy and messy. Not the kind of day you drive for.
The one real highlight, the day that stands out, is Monday the 7th of September. The morning still has that cross-off wind, but the afternoon shifts. The wind goes light, just 3 mph from the NNW, turning offshore and glassy. The swell drops a touch to 8 ft but the period lengthens to 11 seconds, giving the waves real shape and power. The combined energy is still a very strong 1970. This is the window for experienced surfers to score clean, well-shaped reef waves. The water temperature is around 81°, which is about average for this time of year.
That afternoon on the 7th is your winner. After that, the 8th brings a steep drop in energy (down to 504) with onshore winds. There’s a small bounce back on the 9th with 7 ft waves and clean morning conditions, but the wind ramps up again through the day. The second week is a total write-off—small, weak, and disorganized, with energy readings dropping as low as 179. Not much to work with at all.
Bottom line: if you want a wave, aim for that Monday afternoon, the 7th. The rest of the run is either too windy or too flat to get your hopes up.
Rusty.
