The Lowdown

Alright, crew, Rusty here. Let’s cut to it: the next fortnight at Tengan is mostly a grind, with a long flat spell up top and one serious, late pulse of swell that will sort the men from the boys.

Right now, Thursday the 10th is the only early action, with 4 to 5 feet of NE swell. It’s cross and a bit weak in energy (323 and 417), so while it’s the biggest thing around for a while, it’s still marginal. Don’t go in expecting miracles. Then the lights go out. From Friday the 11th through the 19th, it’s a proper flat spell. We’re looking at dribbly 2 to 3 feet at best, mostly onshore or cross-onshore winds, and energy readings that are mostly weak. There’s a lot of sitting on the sand and watching the horizon during this stretch.

The game changes Sunday the 20th. A big ESE groundswell pushes in, going from 6 feet in the morning to 8 feet in the afternoon. The period stretches out to 16 and 17 seconds – that’s deep ocean energy. Energy readings are strong (1826, then 3137). But the wind is up and it’s cross-onshore, so the surface is going to be lumpy and hard to ride. Monday the 21st is all-time in size, with 10 to 12 feet of swell and 18-second periods, and energy readings of 6621 and 8222. But a near gale is blowing at 50-55 km/h, and it’s totally blown out. That’s more of a kite day, frankly. Anything over 8 feet is expert-only, and with that wind, it’s a washing machine.

Tuesday the 22nd is the one to circle. The wind goes cross-offshore and the swell drops from 8 feet to just under 7 feet through the day. The period is still a robust 16 seconds and the energy readings are very strong at 4017 and 3180. The morning session is for experts, but it’s the cleanest big surf we’ll see. Wednesday the 23rd is a solid backup: 7 feet of swell with an 11-second period, cross-offshore wind, and energy readings of 1307. The morning looks cleanest. The swell direction is a bit more N, but the reef will handle it. After that, it fades fast into the 24th and 25th with poor conditions again.

So, mark your calendar for Tuesday the 22nd. It’s going to be big, powerful, and with the cross-off wind, it’s your best shot at a proper wave in this whole outlook. Wednesday morning is the runner-up. The rest is a waiting game.

Rusty out.

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.
