The Lowdown

Alright, Rusty here. Let’s talk about what’s on offer at Tengan. This is a reef setup, and it’s an inconsistent little number that’s fairly exposed to the swell, with an optimum from the NE. The water temp is about average for this time of year, so nothing unusual to report there.

The truth is, the next week and a half is looking pretty grim. We’ve got a long gap of dud surf ahead. For the first several days, the waves are either onshore, messy, or just plain weak. The first real flicker of hope doesn’t show up until Thursday, September 3rd. That afternoon, we get a 4ft swell from the E with a 10-second period, and the wind swings offshore from the W, cleaning things up. The combined energy is moderate (292), and it’s a marginal call, but it’s the best we’ve seen. Still, don’t expect much.

The next notable moment is Saturday, September 12th. The afternoon brings a 10ft swell from the NNW, period around 9 seconds. That’s a big lump of water, and the combined energy shoots up to 1481—strong. The wind is cross-offshore, so it’s clean. But 10ft is expert territory, and this is a reef break, so only the most experienced should be looking at it. The crowd situation is “sometimes,” so there could be a few others out there, but it’s not a circus.

The rest of the second week fades out with onshore slop and strong winds, nothing worth chasing. The standout is that Saturday, September 12th afternoon window, but it’s a long way off and the confidence is low. For now, it’s a waiting game.

Rusty.

Information about the Tengan Surf forecast

The above surf forecast table for Tengan provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Tengan can be found by selecting the local surf guide option on the grey menu. Our Tengan surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Tengan) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Tengan may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.

Tengan is 5 km (3 miles) from the city of Ishikawa. If you plan a holiday in Okinawa, look for hotels and other accommodation in Ishikawa. Ishikawa has rooms for a wide range of budgets as well as car hire and transport links.
