Nai Harn Beach Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what Nai Harn Beach (Phuket) has in store for us.

Honestly, mate, the next couple of weeks are looking pretty grim for a paddle. We’ve got a long stretch of messy, onshore wind and junky surf that’s going to make things tough. The water temp is about average for this time of year, nothing unusual there.

The outlook starts with almost nothing on Thursday the 13th – just tiny 0.3ft dribble from the west with a long period but no energy (combined energy of 10). Not worth getting wet for. Friday the 14th sees a bump in size, with 4ft to 5ft west swell, but it’s coming in at a short, weak 6-7 seconds and a fresh cross-onshore breeze at 19 mph, making it lumpy and poor. The energy picks up a bit (110-235), but the quality is still garbage.

Saturday the 15th and Sunday the 16th bring a bit more size, with 6ft to 6ft west swell, but again, it’s short period (7-8 seconds) and hammered by fresh cross-onshore winds. The combined energy gets up into the 300s and 400s, but it’s all wind-affected slop. This pattern of messy, onshore conditions continues right through the next week, with size fluctuating between 5ft and 7ft. The wind stays stubbornly cross-onshore, mostly from the west at 16-22 mph. The only glimmer of hope is on Monday the 24th morning, where we finally see a bit of a drop in the wind to a gentle breeze and the swell direction turns a little more favorable (on-shore from the WSW). The combined energy hits 749, and it’s our only session that rates above a zero, scoring a 1. It’s still a marginal, questionable call with 8ft west swell and 8-second period, but it might be the best of a bad lot for stronger intermediate to expert surfers willing to wrestle it. After that, the surf drops away into tiny, weak waves again toward the end of the month.

So, the real standout here is that Monday morning, the 24th of August. It’s the only session where the stars align even a little bit. Expect 8ft of west swell, period around 8 seconds, with the wind finally turning onshore and light (9 mph). The wave energy is solid (749), but it’s going to be a raw, powerful wall. This is not a beginner wave – that size is strictly for those who know what they’re doing. The crowds are listed as ‘sometimes’, so you might have some company, but with conditions being so marginal, it shouldn't be packed.

Other than that one window, the entire 16-day run is a write-off for quality surf. For the most part, this setup looks more interesting for kite surfing than paddle surfing, with that persistent cross-onshore wind. That’s the reality here.
