The Lowdown

Alright, Rusty here. Let’s talk about the next couple weeks. The first week is a total bust – almost no surf at all.

From Sunday, July 26th through Sunday, August 2nd, we’ve got tiny waves, mostly 0.6ft to 1.0ft from the southeast, with weak energy readings between 3 and 20. Winds are all over the place, but the waves are just not there. Water temp is about average for this time of year. Don’t bother paddling out.

Then, on Monday, August 3rd, things start to change. The swell picks up to 2ft from the east, with a 14-second period – that’s real groundswell. Energy jumps to 117, and it’s glassy in the morning. Still small, but it’s a sign.

The real action is from Tuesday, August 4th through Saturday, August 8th.

Tuesday the 4th: swell builds to 3ft to 4ft from the east, with a period of 16-17 seconds. That’s very long period, meaning power and shape. Energy is moderate to strong (507-691). Winds are offshore or light cross-offshore, keeping it clean. Tengan is a reef break, and this east swell is perfect for it.

Wednesday the 5th: 4ft to 5ft east swell, still 16 seconds, energy 907-1052. Clean with light offshore winds.

Thursday the 6th is a standout. Swell hits 5ft to 5ft from the east, 17-18 seconds. Strong energy (1359-1540), and offshore winds. This is expert territory – over 5ft on a reef is serious. The long period means long lulls between sets, making it easier to get out, but the waves will be powerful and lined up.

Friday the 7th is the peak: 6ft east swell, 17-second period, energy over 2000 (2039). Offshore in the morning, glassy in the afternoon. That’s excellent, heavy surf for experienced surfers only.

Saturday the 8th still has 6ft to 6ft east swell, 16-17 seconds, with glassy conditions in the morning. The afternoon gets a little cross-shore, but the morning is prime.

After that, it fades. Sunday the 9th has 5ft to 5ft, but onshore winds chop it up. Monday the 10th is junk – 3ft and 22 mph cross-onshore winds.

Bottom line: if you’re an experienced surfer, the best days are Thursday, August 6th and Friday, August 7th at Tengan (Japan). Clean, powerful east swell with offshore winds. For everyone else, this one’s a pass.

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.
