The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.
Honestly, the outlook is a bit of a tough one. We’re looking at a long stretch of barely any waves to start. The first solid recommendation doesn’t pop up until the 28th of July, so there’s a big gap of about a week and a half with nothing worth paddling out for. The forecast is clear for most of that time, but the swell is tiny, around 0.7 ft to 1.0 ft, so it’s just not doing anything. The water is a bit colder than usual for this time of year at 81°, not a big deal, just something to note.
The standout for the whole period, without a doubt, is Tengan on the 28th of July. Tuesday morning rolls in with a solid 4 ft swell from the SE, with a period of 15 seconds. That’s a proper groundswell, and it’s got a lot of energy behind it. The wind is cross-on from the NE at 25 km/h, which isn’t perfect, but it’s manageable. Come Tuesday afternoon, it builds to 5 ft, period 14 seconds, and the energy is getting into some proper size. The waves will be cleaner in the morning, but the afternoon is a bit lumpy with the wind. This is a reef break, so that long period will produce some nice lines, but it’s not for beginners – 5 ft is getting into the intermediate zone.
The 29th of July is big, but it’s a bit of a wild card. Wednesday morning brings a 8 ft swell from the SE with a 14-second period, and the energy is huge. That’s strong. But the wind is a strong cross-shore at 45 km/h, with thunderstorms and risk of rain. It’s going to be messy and pretty ugly. This is only for experts, and even then, it’s going to be a battle. The wind is going to chop it up, so maybe more of a kite-surfing day than a paddle-surfing one.
The 30th of July is the biggest, but it’s blown out. Thursday morning we’ve got a 20 ft swell from the N, with a period of 11 seconds, and the energy is insane. But the wind is near gale force from the SSE at 60 km/h, with rain. It’s a total write-off for surfing. The afternoon is a bit smaller at 13 ft, but still blown out with near gale winds. This is pure chaos.
So, to sum it up: the 28th of July is the pick of the bunch. The 29th is for the brave, and the 30th is for the crazy. Everything else is a flat spell. Keep an eye on the forecasts, because things can change, but for now, you’re waiting till the end of the month.
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.
