The Lowdown
Alright, let's switch gears and talk feet, degrees, and miles per hour for the same spot.
We are in for a tough stretch to kick things off at Little Austi and Main Beach. From Thursday, July 23rd, right through until Monday morning, August 4th, the surf is basically non-existent. We’re talking knee high or nothing, with no punch at all. It’s a real bummer. Might as well stay home and watch the cams.
But hold up, because a monster swell is coming. Around Tuesday, August 4th, we see a jump. Tuesday morning brings a solid 10-foot swell from the ESE with a 12-second period and a combined energy of 2802. That’s a lot of water moving, but the wind is onshore from the SE at 12 mph, making it a choppy, challenging mess. Anything over 8-foot is expert territory, and this qualifies. The water temp is a touch warmer than average for this time of year, hanging around 65°F.
The real gem in this forecast, the absolute standout, is Friday morning, August 7th. The swell is still a potent 12 feet from the ESE, with a good long period of 13 seconds – that’s proper groundswell. The best part? The wind goes light offshore from the NNW at just 3 mph. That is going to groom this massive swell into perfection at this exposed (Big Island) lineup. The combined energy is a massive 3687, so you'll feel the power. This is a big, raw ocean swell. It’ll be a heavy, expert-only session with some serious size, but the clean conditions will make for some epic, spitting waves for those brave enough. Get on it.
