The Lowdown
G’day, Rusty here. The outlook for Grajagan Bay (G-Land) is a solid run of serious, groundswell-driven reef breaks. This is a truly standout stretch for advanced surfers only, with a big, long-period SSW swell that’s just about locked in for the whole sixteen days. The water’s sitting at 77°, which is a touch colder than average for this time of year, so you might want a light spring suit.
The action kicks off from Monday morning, August 10th. The swell is pumping at 7ft from the SSW, with a very long period of 19 seconds and combined energy at 4307. That’s proper groundswell energy, and with a light SE breeze keeping it clean, the morning session is the standout. These long-period waves are best on the reef here, but they’ll be powerful and fast, so only for the experienced. The rating is top-notch for the experienced crowd.
Monday afternoon holds, but the swell jumps to 10ft and the wind picks up to a moderate breeze, making it more marginal. Tuesday morning, August 11th, is another 10ft monster with a 17-second period and energy at 5650. The wind is still a gentle cross-off, so it’s clean. But the real standout for the week is Tuesday afternoon, where the swell is still 10ft, the period stretches to 19 seconds, and the energy hits 8639. That’s massive power, and the wind is a moderate cross-off, so it’s on the edge of being too big for anyone but experts.
The pattern continues through Wednesday, August 12th, with a 8ft swell and 17-second period in the morning, then easing to 7ft in the afternoon. The energy stays well above 2000, so it’s still a heavy wave, but the wind and tide conditions make it feel more marginal. Thursday morning, August 13th, is another excellent shout for experts: 10ft, 17-second period, and a gentle cross-off. The energy is 4254, so it’s a powerful, clean morning.
Friday, August 14th, sees the swell drop a touch to 8ft, but the period is still a solid 15 seconds. The morning has some clouds and a light breeze, keeping it clean. The energy is 3108, so still a proper wave. The weekend, starting Saturday, August 15th, has a 8ft swell with a 17-second period. The morning is excellent, with a light breeze and energy at 3304, while the afternoon gets a bit more wind. Sunday, August 16th, is similar: 7ft, 16-second period, and a light breeze in the morning making it clean (energy 2441).
Into the second week, the swell stays consistent but eases slightly. Monday, August 17th, sees 5ft in the morning with a 14-second period and energy at 1077. It’s still clean and excellent for the experienced, but the power is dialing back. Tuesday, August 18th, through Friday, August 21st, the swell hovers between 7ft and 8ft, with periods of 15-17 seconds, and the wind is a steady cross-off from the SE or ESE. Energy values are mostly in the 2000-3500 range, so it’s a persistent, strong groundswell.
The last weekend, August 22nd and 23rd, holds 7ft and 4ft swells respectively. The 23rd is interesting: a 4ft swell but with a very long period of 20 seconds, and energy at 2818. That’s a deceptive amount of energy for the size, and with a light breeze in the morning, it’s clean and excellent for the experienced. The final Monday, August 24th, is a standout for the second week: 10ft, 17-second period, and a light SE breeze. The energy is 4409, and it’s an excellent morning for the crew who can handle it. Tuesday, August 25th, closes out with a 7ft, 15-second period and a light breeze.
The best of the best? You’ve got two true standouts. The first is Tuesday, August 11th, afternoon session: 10ft, 19-second period, and 8639 energy. That’s as good as it gets for experts. The second is Monday, August 24th, morning: 10ft, 17-second period, light breeze, and 4409 energy. Both are massive, clean, and powerful. Beginners, steer clear—anything over 5ft is too big, and these are way over 8ft, so it’s experts only. Crowds are possible at G-Land, so expect company.
This is you, Rusty.
