The Lowdown
Alright folks, Rusty here. Let's be straight with you. Looking at the whole 16-day window for our stretch of coast, and I gotta be honest with you, it’s a grim picture for the most part. The surf finder is coming up empty-handed for the entire period, which is a real kick in the teeth. But that doesn't mean we're totally sunk – it just means we have to be patient and read the ocean right.
The first week is a write-off. We're looking at a whole lot of flat, junky conditions. Through the 5th and 6th, we've got some weak, short-period swell, but it's all tangled up in cross-onshore winds, making for poor, choppy surf. The energy is weak, sitting around 154 and 132, which is just nothing to get excited about. From the 7th right through to the 12th, it's essentially flat. There are a few glassy mornings, like the 7th and the 11th, but with waves barely reaching 0.3ft, it's a lake out there. The water temp is about average for this time of year, so you won't need the thickest suit, but you'll be doing more floating than surfing.
There's a slight pulse of energy mid-month, around the 13th and 14th, but it's still tiny – ankle to knee-high. The mornings have a cleaner cross-off breeze, which is nice, but there just isn't enough push to make it worthwhile. The energy jumps a bit to 46 and then 62, but it's all for nothing.
Then, the second week gets interesting. We see a real uptick in energy starting Monday the 17th, but the wind is howling from the northwest, making a mess of things. This all builds into a proper swell for the 18th and 19th. The energy readings are strong, hitting 320, then a solid 517, and even peaking at 673 on the Wednesday morning. The swell height is also getting up there, around 5ft to 6ft, with a period of 8-9 seconds. But here's the catch: the winds are still cross-shore and fresh, so it's going to be lumpy as anything. With waves over 5ft, this is pushing past beginner territory, and with that junky wind, it's not going to be a fun paddle for anyone. At Whitsand Bay and Tregantle, which is an exposed beach setup, this is looking less like a surf session and more like a kite-surfing day. The swell direction is WSW, which is in the right zone, but the conditions are just against us.
So, the long and short of it is this: there are no good surf options in this 16-day window. It's a blank run. But don't lose hope, this spot is fairly consistent, so it tends not to stay poor for long, and forecasts can change. Keep your eyes on the charts and your board ready for when it does turn on.
For now, the best you can hope for is a few glassy dawn patrols to get your fix, even if it's just for a paddle. Hang tight.
