Updates in hr min s Forecast update imminent
Alright folks, Rusty here. Let’s talk about what’s on offer for the next couple of weeks.
Right off the bat, it’s dead quiet. From the start of July all the way through Monday the 6th, we’ve got a long run of small, weak surf with cross-off breezes that just aren’t giving us anything. It’s a proper flat spell that’s not worth a second look.
Then, Tuesday the 7th is the day that jumps out. We’ve got glassy, clean conditions in the morning with a light offshore wind. The swell is around 3 ft from the ESE, and by the afternoon it’s pushing a solid 3 ft with a period of 17 seconds – that’s long-period groundswell, so more push and shape. The wave energy climbs into moderate territory. For a reef break like Tengan that’s open to the NE, this long swell will wrap in nicely, giving us clean, lined-up waves. The water is around 81°, just a touch cooler than usual for this time of year. Tuesday is the session.
Wednesday the 8th gets messy. The swell jumps to 7 ft in the morning, but the wind turns cross-onshore from the north-northeast. By the afternoon, the wind is blowing 25 km/h and the wave height hits 8 ft. The energy is strong, but the surface gets messy and choppy quickly.
Thursday the 9th is no good for surfing. We’re looking at 12 ft of SE swell with a fresh cross-onshore wind of 30 to 35 km/h and risk of thunderstorms. The energy is huge, but the quality is garbage. This one’s more for the kite crew.
From the 10th onward, it’s a write-off. Onshore winds, more storms, and only tiny waves – 0.7 ft to 3 ft at best, with short periods and poor conditions. No consistency, no power. The second week is a total bust.
So, keep it simple: Tuesday the 7th is your best bet for clean, fun waves. For the rest, just save your energy.
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.
