The Lowdown

Alright, let’s talk surf, same setup, but in feet and miles for those who think in imperial.

Right now and for the next few days, it’s a total lull. Nothin’ doin’. Swells are barely a foot, if that, through the end of July and into the first days of August. Combined swell energy is in the single digits to low teens most of that time. Wind’s sometimes clean, but there’s no ocean energy to work with. Don’t even bother.

Things start movin’ Monday the 3rd of August. East swell around 2ft to 2ft, 14 to 15 second period. Not great, and the wind’s cross-onshore in spots, but energy climbs to 121–203. Still just teasin’.

Tuesday the 4th of August, we get cleaner conditions and the swell bumps up to 3ft to 4ft from the east, 16-second period, with cross-offshore wind in the afternoon and energy at 660. That’s the first real chance for a session.

But the standout is Wednesday the 5th of August through Saturday the 8th of August. Wednesday the 5th, Tengan (reef) has 5ft of east swell with a 17-second period, clean cross-offshore breeze, and energy at 1163. That’s a solid groundswell for the reef. The water’s about 85°, just a touch warmer than average. Then Saturday the 8th of August is the big day: 8ft of east swell, 18 to 19 second period, glassy conditions, and energy hammerin’ 5089 in the morning and 4396 in the afternoon. That’s strong. Tengan doesn’t fire often, so when it does, you take notice. But 8ft-plus on a reef with that kind of period is expert territory only. If you’re not ready, don’t risk it.

After that, Sunday and Monday drop in quality. Waves stay in the 5ft to 8ft range but wind shifts onshore and the period drops, makin’ things messy. By Tuesday the 11th of August, we’re down to 5ft to 6ft, energy fallin’ to 540-592, and the wind’s still not helpin’.

So here’s the take: sit tight through the flat spell. The window opens Tuesday the 4th, but the best swell of the whole run is Wednesday the 5th through Saturday the 8th. Saturday the 8th is the absolute peak – for experienced surfers only.

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.
