The Lowdown
Alright, Rusty here again, switching to feet and degrees for the imperial crew.
Let’s break down what’s cooking at one of the world’s most famous left-hand reef breaks. We’ve got a solid stretch of swell from Sunday, September 6th all the way through to Monday, September 21st. No waiting around – the surf is on from the get-go. The wind is locked in from the SSE to SE, blowing cross-off the whole time, which is exactly what you want for those long, grinding barrels at Grajagan Bay/G-Land. Water temp is 78°, pretty much normal for this time of year.
The first couple of days are just getting things going. Sunday afternoon the 6th brings in a 6 ft SSW groundswell with a 16-second period – that’s proper energy, and the combined swell energy is reading 2523, which is strong. Monday the 7th has a 8 ft swell in the morning dropping to 6 ft in the afternoon, but the forecast calls it marginal, so don’t expect perfection yet.
Now for the standout. Wednesday morning, September 9th is the one. We’re looking at an 8 ft SSW groundswell with a 16-second period, and the combined energy is cranking at 3412. The wind is a light 9 mph cross-off, keeping the surface glassy. This is top-tier, expert-only territory. Anything over 8 ft out here is for the big-wave chargers.
Thursday the 10th morning is also solid at 7 ft with light 6 mph winds, and Friday the 11th morning has 7 ft with light 6 mph winds – both flagged as excellent. The crowd factor is “sometimes,” so expect a few other souls in the water, but the consistency is “very consistent,” so you’ll get waves.
Into the second week, the swell drops a bit, staying between 5 ft and 8 ft, with that long-period groundswell sticking around. The period drops to 14-15 seconds, so the sets will be a bit more frequent. The wind stays cross-off from the SE, so it stays clean. Saturday the 19th morning picks up again to 7 ft with a 17-second period, looking like a solid late option.
Bottom line: if you’re an experienced surfer, the first half of this forecast is absolute gold. The pick of the pack is Wednesday the 9th morning. Don’t miss it.
Rusty.
