Nai Harn Beach Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s break it down.

Right off the bat, I gotta be real with you – Nai Harn Beach is having a rough run. The forecast is a long, frustrating stretch of poor conditions. There’s a massive gap of no good surf from now until September 1st. That’s nearly two weeks of washing your car or doing something else. The wind is just relentless, coming from the west and southwest, smashing us with cross-onshore chop for days on end.

The first and only real flicker of hope comes on Tuesday, September 1st. The morning looks like a tiny window of clean conditions. The wind swings around to a light cross-offshore from the north-northwest, finally giving us a break. The swell is tiny, only 1ft from the west-southwest, but it’s a long-period groundswell (19 seconds). That’s a classic Nai Harn setup for a glassy, clean little wave. The combined energy is weak at 120, but when it’s that clean, you don’t need much. It’s the only surflable option in the whole 16-day window. Expect it to be inconsistent, though, as it rarely breaks well.

That afternoon, the wind turns back on, the swell drops further, and we’re back to square one. The rest of the forecast is just more of the same: strong cross-onshore winds, lumpy water, and the occasional spike in swell size that’s completely ruined by the wind. Look at the 28th of August, where we get a 7ft swell from the west, but it’s accompanied by a 22 mph cross-onshore wind. That’s a washing machine, and for a beach-and-reef setup, that’s more of a kite-surfing afternoon than a paddle-surfing one.

The water temp is sitting at 86°F, which is pretty normal for this time of year, so at least you won’t freeze waiting for the sets that never come.

So, if you’re committed, mark your calendar for the morning of the 1st of September. That’s the only stand-out, and it’s a gamble on a tiny, inconsistent swell. Otherwise, the rest is a write-off.

Rusty.
