The Lowdown
Right, folks, Rusty here with a look at what's coming our way over the next couple of weeks. Straight up, we've got a bit of a flat spell to start with.
For the first few days, from Sunday the 16th right through to Monday the 24th, it's looking like a proper write-off for any decent waves. We're just not seeing the energy. That southeast-to-east swell is way too small and weak, with the combined energy barely hitting double digits (7 to 23). So, there's a good week of nothing much to talk about, just tiny 0.3ft dribble. You'd be better off taking the gear down to the beach and just enjoying the sand.
Now, the good news starts to show up later in the week. Things get interesting on Thursday the 27th. We finally see a pulse of swell coming in, with a long-period groundswell aiming for the coast. It's still on the modest side at 1ft, but the direction from the east looks right.
The standout morning is Friday the 28th. We've got a fresh offshore wind from the WSW blowing at 19 mph, cleaning up those 1ft waves at Walton Rocks (Power Plant). That offshore breeze will be a dream, shaping those little lines up nicely. The combined energy is still light, but the quality from the wind will be mint. That same pick-up carries into Saturday the 29th, with more offshore wind in the morning, but that one's a week and a half away, so keep an eye on it. The water temp is sitting around 86°, which is about average for this time of year, so no need for a thick suit.
All in all, don't hold your breath for the first week. If you've got to paddle, target the end of August for that offshore window.
Rusty.
