The Lowdown

Alright, I’ll level with you – it’s a tough stretch for Tengan. This reef doesn’t break often, and the next couple of weeks are looking pretty poor for a proper surf. There’s a long gap where you won’t find anything worth paddling out for.

Water temp is about 86°, a touch warmer than usual for this time of year at Tengan.

Your first possible look is Friday the 14th of August. In the morning, there’s a tiny 1 foot swell from the north, with a short period of 7 seconds and very weak energy (8). The wind is offshore from the west, so it’d be glassy, but you’d be hunting for a wave that’s barely there. The afternoon goes flat.

Saturday the 15th of August shows a 1 foot swell from the east, period 6 seconds, energy of 12 – still very weak. The wind is light cross-shore in the morning, so it’s not blown out, but the waves are small and crummy.

From the 16th of August onward, it’s onshore winds and nothing but small, short-period junk. The 2-3 foot readings from the 21st to the 23rd of August are from the east-southeast, with periods of 7-9 seconds and combined energy up to 94, but fresh onshore winds will chop it all up. The 23rd of August has the most energy (94) with a 3 foot swell, but the onshore wind ruins it.

Honestly, there’s no standout session here for the next 16 days. This reef is inconsistent and needs a proper swell with clean wind. Your best bet is a longboard on Friday the 14th of August morning if the offshore holds, but it’s a real gamble. For a wave, you might be better off on a lake or just taking a break. This kind of dry spell is pretty normal for Tengan when the weather patterns lock in.

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.
