Nai Harn Beach Surf Forecast and Surf Report

Alright, Rusty here again. Gotta be straight with ya: this outlook for Nai Harn Beach is a real tough one to write. We’ve got a full 16-day window, but honestly, there’s just nothin’ worth paddling out for. The whole stretch is a write-off.

From now through to the end of the first week, it’s just a constant battle. You’ve got cross-onshore winds hammerin’ the place, mostly from the W and WSW, gustin’ between 15 and 22 mph, which is just tearin’ the surface to bits. Even when there’s a bit of size—like on the 30th of August through the 31st of August, where we see swell around 6 ft to 7 ft from the west, with the combined swell energy hittin’ 406 to 526 (moderate to strong energy)—the wind is so bad it’s just lumpy, choppy, and messy. The period is a short 7 to 8 seconds, so it’s just weak, blown-out wind swell. Not even close to surfable.

There’s a bit of a tease early on the morning of the 26th of August with a 5 ft west swell (243 combined energy), but again, it’s got that same cross-on wind and a short period. Any hope is quickly dashed. By the 1st of September, it fades to tiny 1 ft stuff with a long 18-second period from the WSW (106 energy), but the wind is still cross-on, so it’s a no-go. The water temp is sittin’ around 86°, with just a 2° anomaly above normal, so it’s unseasonably warm but nothin’ wild.

Then we hit a real dead zone. From the 2nd of September all the way through the 8th of September, it’s flat. We’re talkin’ swell heights of 0.3 ft to 1 ft, energy levels droppin’ into the single digits and twenties. The wind stays miserable, mostly from the WNW. It’s a total blank stretch.

Now, on the 9th of September, we get a late spike of energy—6 ft to 7 ft from the west again, with combined swell energy up to 318 and 363 (moderate to strong), but the period is only 7 seconds, and that wind is still hammerin’ cross-on from the W at 19-22 mph. The wave comment says it all: “poor surf conditions.” This setup looks more interesting for kite surfing than paddle surfing. For a surfboard? Forget it.

Nai Harn Beach is a beach and reef setup, exposed to the west, but the conditions just aren’t aligning. It’s an inconsistent spot, and this run proves it. We don’t get that magic window of clean swell with offshore wind anywhere in this 16-day span. It’s just not happening.

Keep an eye on it, but for now, don’t waste the gas.

Rusty.
