The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on offer for Tengan over the next couple of weeks.

Right off the bat, I’ve gotta be straight with you – this is a tough one. The whole 16-day window is looking pretty flat and sad. The wave energy is basically non-existent, with values barely tickling double digits most days. We’re looking at a long stretch of small, weak, and messy conditions. Honestly, for the first week and a half, there’s just nothing to get excited about. You’d be better off cleaning your board or checking the tide pools.

The first faint glimmer of anything happens way out on the 28th of July. Tuesday afternoon, we get a westerly breeze turning offshore, and the swell bumps up to a tiny 2ft from the ESE. The energy is still pretty weak at 75, but with a clean, offshore wind, it might just be rideable for a beginner on a log. It’s a long shot, but it’s the best we’ve got.

Then, later in the forecast, around the 4th and 5th of August, the swell tries to pick up a bit. We see some 3ft to 3ft easterly swell, and the energy finally gets into the low hundreds (114 to 128). But here’s the kicker – the wind is howling onshore from the southeast, making it a total mess. The wave comment says it all: “fresh cross-onshore and lumpy.” This is kite-surfing territory, not paddling. If you’re a surfer, you’ll be fighting a losing battle against the chop.

The one spot to keep an eye on is Tengan itself. It’s a reef break, which is a bit of a positive because it can handle some swell, but it’s inconsistent and only really works with a NE swell. The forecast is sending swell from the east and southeast, so it’s not hitting the optimum direction. The water temp is about average for this time of year, so no need for a thick wetsuit.

Bottom line: put the board away for a bit. There’s nothing worth paddling out for in the first week, and the second week offers a choice between a tiny, clean wave or a bigger, blown-out mess. It’s a dry spell, and for this area, that’s not totally unusual. Let’s hope the models change.

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.
