The Lowdown
Alright, let’s talk about what’s on offer for the next couple of weeks around Tengan (reef break, beginner spot, inconsistent). I’ll be straight with you – there’s a long, dry stretch at the start. From now, Sunday 19 July, right through to Tuesday 29 July, there’s basically nothing worth paddling out for. The waves are tiny – 0.7ft to 1.0ft – and even though the wind is glassy or light offshore on a few mornings, the energy is just too weak (combined energy in the single digits to low 20s). You’re looking at a full 11 days with no real surf. The water temperature is sitting at 82.2°F, which is a bit colder than usual for this time of year – about 2.3°F off the average, so you’ll notice it’s a touch cooler than normal.
Then on Wednesday 30 July, things start to pick up. The swell builds, but it’s not a friendly wave. On Thursday 30 July morning we get 8.2ft from the north-northwest with a 14-second period, and strong offshore winds from the west at 25 mph. The combined energy jumps to 2491 – that’s moderate to strong. The conditions are clean, but that offshore wind is gusty and strong, making it hard to paddle into. Same story on Friday 31 July: 11.5ft to 14.8ft from north to north-northwest, periods around 13 seconds, and west winds 25–28 mph. Energy is huge – 5697 to 6020. The waves are clean but you’ll be fighting to get in. This is expert territory only – over 8ft, and with that strong offshore it’s not for beginners. Also Tengan is inconsistent, so don’t expect it to be pumping every set. Crowds are possible.
Saturday 1 August still has 9.8–11.5ft from the north, but the offshore wind eases a bit to 25–28 mph, energy still strong at 3154–3811. Still clean but still a battle. After that, Sunday 2 August and Monday 3 August drop off again – smaller swell and cross-off or cross-onshore winds, so the window closes.
If I had to pick the best of a messy bunch, it’s the afternoon of Friday 31 July and the morning of Saturday 1 August. The swell is solid, the wind is offshore and clean, but it’s a serious session for experienced surfers only. Don

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.
