Nai Harn Beach Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s happening with Nai Harn Beach over the next couple of weeks.

Straight up, I gotta be honest with you – this is a tough period for paddlers. We’re looking at a long stretch of poor surf conditions kicking off Thursday, July 23rd, and running right through. The wind is mostly cross-on or onshore, and the swell is messy and short-period. The first real surf window is basically non-existent for a good week or more.

Let’s break it down. We start Thursday morning, July 23rd, with a weak 3ft swell from the west, period a tiny 6 seconds, and a risk of thunderstorms. The combined energy is a weak 54 – that’s barely a ripple. The wind is a moderate cross-onshore breeze, making it choppy. This theme sticks around for days. Friday and Saturday bring similar, with height nudging 3ft to 4ft, but the wind stays fresh and lumpy, and the energy is still low (54 to 104). It’s not surfable in any decent way.

Sunday, July 26th, through Monday, July 27th, we see a bit more size – up to 4ft – but the wind is fresh and howling, and the swell period is still a short 6 seconds. The energy climbs to 113, but it’s all wind chop. Monday afternoon actually brings a 7ft swell from the west with a 7-second period and energy jumping to 418, but it’s accompanied by a fresh cross-onshore gale. That’s going to be a washing machine – big, messy, and blown out. Not for beginners, and honestly, not great for anyone.

Tuesday, July 28th, and Wednesday, July 29th, keep the 6ft to 7ft west swell, with periods slowly creeping to 8 seconds. The wind is still up, but shifting to more onshore. The energy is strong (around 400), but the quality is poor. This is expert-level size in messy conditions. By Thursday, July 30th, the swell drops off a cliff to 0.3ft with a very long 21-second period – that’s a ghost swell, barely making it over the reef. The combined energy is just 12.

There’s a long gap of nothing through the end of July and into the first days of August. The swell is tiny, and the wind is moderate to fresh. Not a sniff of a wave.

Now, August 5th and 6th start to look interesting for the wrong reasons. We get a building west swell hitting 8ft to 8ft, with a 8-second period, and strong energy in the 514 to 847 range. But the wind is still a strong cross-onshore breeze, making it messy. For a beach and reef setup like Nai Harn, this is big, powerful, and blown out – honestly, this setup looks more interesting for kite surfing than paddle surfing. It’s too big for beginners, and only for experts willing to battle the wind.

The only break on offer is Nai Harn Beach itself, a beach and reef setup exposed to the west. The optimum swell direction is west, which lines up with a lot of the swell, but the wind just never plays ball. Crowds are possible here, but with conditions this poor, I doubt many will be out.

The water temperature is about average for the time of year, no major anomaly to report.

The bottom line: There are no good surf options in this 16-day window. The entire period is a write-off for quality waves. It’s a blank run, and for this area, that’s not unusual when the monsoon winds lock in. Don’t leave your board in the car just yet – forecasts can change, but right now, I’d take the fins off and have a beer.

Rusty.
