The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the table for the next stretch around Grajagan Bay, or as most of you know it, G-Land. This is a proper, world-class left-hand reef that doesn’t mess around. It’s exposed to the open ocean and very consistent, so when the swell shows up, it shows up.
The water temp here is sitting about average for the time of year, so nothing too wild on that front—just your typical tropical warmth. Grab a steamer if you’re a wimp, but honestly, it’s fine.
Now, the pattern for these 16 days is a bit of a slow starter, then it builds. We’ve got a few shaky days before things start cooking. From Monday (27 July) right through to Thursday morning (30 July), it’s not looking great. There are waves on offer, but the swell is small or mixed—most of it’s coming in at around 3 ft to 5 ft on the shorter period, and the energy numbers are weak to moderate. The wind is a consistent cross-off from the ESE, which is actually okay for G-Land, but the quality of the swell and the “marginal” call in the data means I wouldn’t paddle out unless I had to. That three-day window is basically a write-off for good surf.
But hold onto your boardies, because things start shifting on Thursday the 30th. The swell jumps a little, the period climbs to 15 seconds, and the combined energy kicks into solid moderate territory. Still, it’s not until Saturday morning, the 1st of August, that we get our first real standout. That morning session is rated as excellent for experienced surfers. We’ve got a nice clean 5 ft SSW groundswell with a 16-second period. The wind is light at 6 mph out of the SE—still cross-off—which should leave the face super clean and ripable. Energy is moderate. This is a reef break, and that long-period groundswell will wrap in beautifully here. It’s an advanced-only wave, but if you’ve got the skills, it’ll be a session you remember. Crowds can show up, but that’s just G-Land.
The next real standout is Sunday morning, 2nd of August. This one is a big one. The swell pumps to 8 ft out of the SSW, period holding at 17 seconds, and the combined swell energy skyrockets to strong territory. Wind is a dream: light breeze at just 6 mph from the ESE, cross-off. That means the wave is going to be big, clean, and powerful. This is an advanced-level setup. It’s going to be challenging for anyone not in the expert category. For the true big wave chargers, this is the call of the forecast period.
Looking further out, things don’t let up. We’ve got solid SSW swell running from the 3rd of August through to the 11th. The energy numbers stay consistently in the strong range. Heights sit between 6 ft and 10 ft. The big standout there would be Saturday the 8th of August, with the early morning swell hitting 10 ft, period at 17 seconds, and energy at a very strong reading. Wind is mild, so it will be one for the experts only, no question. The Sunday the 9th also delivers a massive energy reading in the afternoon with an 8 ft swell, though the wind is a notch stronger.
Don’t expect much from the early days between Monday and Wednesday—it’s basically flat or messy. It’s really from the 1st of August onward that G-Land comes alive. The swell direction (SSW) is spot-on for optimum, and the period (14–18 seconds) is classic groundswell.
There’s a gap in quality surf from now until the Thursday, so don’t get too excited just yet. But trust me—once that first August swell hits, it’s going to be on.
Remember, this is all advanced-level territory. If you’re not comfortable in big, hollow reef waves, sit this one out and watch from the beach.
Stay tuned, and keep the wax warm.
Rusty.
