Tainohama Surf Forecast and Surf Report

Alright, this is Rusty, checking in with the outlook for Tainohama.

We’ve got a bit of a wait for the good stuff this week, but hang in there. The water temp here is running about average for this time of year, nothing wild.

Wednesday’s a write-off with that risk of thunderstorms and onshore wind. The swell is a weak 4ft from the south at a short 8 seconds (energy at 260), so it’s messy, don’t even bother.

Thursday morning is glassy, calm, flat. That’s a teaser for the afternoon. By Thursday afternoon the wind swings to a clean offshore from the north, and we get a pulse of 4ft south-southeast swell at 10 seconds. It’s not huge, but it’ll be clean and fun. The energy is moderate (365). This is your first real chance for a decent session.

Friday sees the swell building Friday morning to 6ft from the south, period at 9 seconds. That’s a solid chest-to-head-high and getting a bit much for beginners. The wind is cross-offshore, so it’ll be clean. The energy is ramping up (620). Friday afternoon drops slightly to 5ft, still clean.

Saturday the swell shifts direction to the east-southeast but the wind howls. Saturday morning is 6ft but with a strong 40 km/h cross-off wind. That’s a mess. Saturday afternoon is 6ft at 8 seconds (energy at 878). The swell is there, but the wind is too strong for good surf. This setup looks more interesting for kite surfing than paddle surfing.

Sunday is where things get serious. Sunday morning we see a jump to 12ft from the east, period at 9 seconds. This is big, solidly in the expert-only zone. The combined energy is very strong (3167). It’s big, but the wind is cross-offshore, keeping it clean. Sunday afternoon drops to a still-big 8ft from the east-southeast at 10 seconds.

The standout, and I mean the standout of the whole window, is Monday the 7th of September. Monday afternoon delivers a 13ft swell from the southeast with a very long 12-second period. That is a proper groundswell. The energy is massive at 7032. Conditions are “fresh offshore and clean”. This is a big, powerful swell, so it’s strictly for experts. This reef is exposed to the south, and with that long period, it’ll wrap in perfectly.

Tuesday the 8th stays big, with a 15ft southeast swell in the morning, but it’s a touch less clean than Monday. Energy is still very strong (4231). Wednesday the 9th is still a solid 8ft, and the afternoon sees a clean offshore wind again. Thursday the 10th and Friday the 11th are messy with onshore winds.

Then we get another little window. Saturday the 12th morning shows an “excellent” call for experienced surfers with a clean 7ft southeast swell, long 11-second period, and light cross-off wind. The energy is strong (1274). Saturday afternoon is glassy with a 6ft southeast swell.

From Sunday the 13th onwards, things turn ugly. The swell is still solid but the onshore winds return, and by the 14th and 15th we’ve got strong onshore winds and heavy rain. The 15th has a 13ft southeast swell at 14 seconds, but it’s blown out. The 16th is still onshore.

Finally, on Thursday the 17th, we get a glassy morning with a clean, small 3ft south swell at a lovely long 12-second period. Energy is moderate (623). It’s a beautiful little window for a clean-up set on a longboard after all that chaos.

But honestly, if you only pick one day, it’s Monday the 7th. It’s the biggest, deepest, most powerful swell of the run with perfect offshore wind. That's the one to dream on.

Rusty.
