Tengan Surf Forecast and Surf Report

Alright crew, let’s get into it. Looking at the next couple weeks, it’s a slow grind to start, with a few windows of hope scattered in there. We’ve got a long stretch of poor conditions early on, but things do start to get a bit more interesting as we roll into the third week. Don’t get too excited too early, but there is something to keep an eye on.

The first real chance to even think about a wave comes in on Thursday the 10th. It’s not going to be pumping, but there’s a hint of life. We’re looking at around 6ft of north-northwest swell with a period around 9 seconds at Tengan. The combined energy is moderate at 498. It’s still a bit messy with a cross breeze, so you’ll be working for it, but it’s surfable. Conditions improve slightly into the afternoon with a lighter cross breeze and the swell holding around 5ft. It’s a marginal call, so don't expect miracles.

After that, it gets pretty grim again. From Friday the 11th right through to the 20th, the surf basically goes flat and onshore winds and storms mess with the surface. This is a long stretch of nothing, a week or more with no decent options. The swell drops, the wind gets ugly, and energy readings are mostly weak, well under 200. On the 18th we get a brief clean offshore window, but the swell is only around 3ft with a short period, so it won’t be doing much. This is a dead zone, so don’t even bother stringing up your board.

Now, here’s the standout. The action starts to build on Monday the 21st of September. We’ve got a proper groundswell arriving from the east with a very long period of 18 seconds. The swell tops out around 7ft, and the combined energy is strong, hitting 2666 in the afternoon. This is the real deal. The winds are tipped to be cross-off and clean, making Tengan (Big Island) look like a solid choice. This reef setup is usually fairly exposed to that north-east swell, and with this kind of period, it should be organizing well. Expect some solid, deep waves. The 22nd also sees good energy with a 5ft east swell and a 16-second period, so this pulse should have some legs.

Keep in mind, we don’t have any solid info on crowds, but spots like this can be popular when the surf finally shows up. It’s been a long wait, so a few other folks might have the same idea.

The water is warm, sitting around 84°F at the start, which is pretty average for this time of year. Bring the boardshorts.

So, don't give up hope. It’s a long, flat stretch, but that end-of-month pulse looks like the one to point the car at. It’s a bit far out, so treat it as promising, but not a done deal yet.

Rusty.
