The Lowdown
Alright, Rusty here. Let's have a look at what's on the table.
Honestly, mate, I'm looking at a flat spell that stretches all the way through the 16-day window. There’s just no surf to speak of. The first record kicks off on the 16th of September, but it's not one to get excited about. The whole period is a write-off for decent waves at Gantheaume Point. The combined energy readings are puny, barely hitting double digits for most of the run – we’re talking a weak 10 to single-digit numbers. It’s heartbreaking.
The water's sitting at 80°, which is a touch warmer than usual for this time of year, but with no swell to enjoy, it doesn’t matter much.
We see some action from a westerly swell that’s mostly around 1 ft to 2 ft, but the period is all over the shop – sometimes it's a short-period 3 seconds, sometimes a long 14 to 18 seconds. That long-period stuff, even if it had any size, would need a proper point or reef to wrap around. Conditions are consistently messy with cross-onshore winds and chop, so the setup looks more interesting for kite surfing than paddle surfing.
The only time it’s clean is on a few mornings like Thursday the 17th and Friday the 18th with cross-offshore winds, but with the swell barely a ripple, you’re just floating. This spot rarely breaks as it is, so a blank run like this is more normal for the area. It’s a tough one to swallow, but that’s the story.
Rusty.
