Nai Harn Beach Surf Forecast and Surf Report

Gather round, crew. Rusty here, and I gotta level with you – the next fortnight or so at Nai Harn Beach is lookin' pretty bleak. We've got a classic case of the monsoon blues settin' in, with onshore winds howling from the west and southwest pretty much non-stop. This cross-onshore flow is gonna chop up any half-decent swell that tries to roll in. The water temp is sittin' at a sweltering 86°, which is about average for this time of year, so at least a dip in the sea will be refreshing, even if you ain't catchin' a wave.

Right now, through Friday morning and afternoon, it's just tiny, gutless 1.0 ft swell from the WSW with a super long period of 17 seconds. That groundswell energy is weak (57), and the wind is straight on it, dirtyin' it up. There's simply nothin' to work with. Saturday ain't any better – we're down to 0.7 ft and the wind goes cross-onshore. This whole first week is a write-off, with onshore winds and tiny or crummy surf. The combined energy rarely cracks 100, it's that weak.

Now, come Wednesday morning the 26th of August, we finally see some size pop up – 7 ft from the west. The combined energy jumps to a moderate 442, which tells you there's some push. But here's the heartbreaker: it's short-period windswell at 8 seconds, and that consistent cross-onshore wind is still blowin' at 30 km/h, making it a choppy, lumpy mess. Thursday the 27th is a similar story with 6 ft and 418 energy, but again, blown out. This stretch right through to the end of August and into early September is nothing but cross-onshore slop. The swell will actually get bigger – we're lookin' at 8 ft from the west on Monday the 31st of August with a strong combined energy of 978 – but with a near gale-force cross-onshore wind (40-50 km/h), it's goin' to be dangerous and completely out of control. That is pure expert-level, survival-only stuff, and the quality will be absolutely terrible. For the average surfer, this setup is lookin' more interesting for kite-surfing than paddlin'.

We do get a tiny window late in the outlook. On Wednesday afternoon, the 2nd of September, we see 5 ft from the west with a period of 7 seconds (389 energy), but winds are still onshore and it's marked as poor. And on Friday the 4th of September afternoon, there's a 4 ft west swell (123 energy) but with a 6-second period and onshore wind. Honestly, none of it is worth paddlin' out for in these conditions. The entire 16-day window is plagued by poor surf quality ratings. It's a tough run, but forecasts can change, and it never stays this bad forever. Keep your eyes peeled.
