Alright folks, Rusty here. Let’s have a look at what Tainohama has in store for us over the next couple of weeks.

Right off the bat, it’s a bit of a slow start. We’re looking at a few days of pretty scrappy, small surf through the first weekend and into Monday. Nothing to get excited about, really. The water temp is about average for this time of year, so no surprises there.

The first real glimmer of hope comes on Monday, July 6th. A glassy morning with 2ft on offer. The wave energy is still weak (191), but it’s a start. That afternoon sees a bit more size, up to 3ft, with moderate energy (365), but the wind is light and onshore, making it very ordinary.

Things start to build through Tuesday, July 7th. The morning has 4ft of swell from the SE with a 12-second period, and the energy is climbing into the moderate range (787). Wind is light and onshore, so it’s still a bit messy. The afternoon really gets interesting though: 5ft of SE swell, a very long 17-second period, and the energy jumps to strong (1442). Winds are light onshore, so it’s marginal, but you can feel the pulse coming.

Now, here’s where it gets serious. Wednesday, July 8th, the swell pumps up to a solid 10ft from the SE, with a 17-second period. That’s a big, powerful groundswell. The energy is very strong (7328 in the morning). This is expert territory only. If you’re not a seasoned surfer, stay well clear. The wind is onshore, making it a bit of a beast, but for the crew who can handle it, there will be some serious, heavy lines.

The swell holds strong through Thursday, July 9th, and Friday, July 10th, with 10ft to 12ft of S/SSE swell, all with long periods (16-17 seconds). The energy stays very strong (well over 5000). Friday morning looks the pick of this mid-week block, with lighter winds.

The standout period, without a doubt, is Saturday, July 11th. The morning is absolute gold. We’ve got 12ft of S swell, a 16-second period, and a glassy, zero-wind morning. That’s exceptional, clean, heavy surf for the experts. The energy is through the roof (6311). This is the session to circle on the calendar. The afternoon will still have size, but the onshore wind will mess it up.

Sunday, July 12th, is still a good option for the experienced crew. The swell drops to 8ft from the SSW, with a 14-second period. The morning has a light, clean cross-offshore wind from the NE, making for some excellent, shaped-up waves. The afternoon turns glassy as the swell drops to 6ft. That’s a solid day for anyone with some experience under their belt.

After that, the swell fades through the middle of the next week. Monday, July 13th, offers some clean, fun-sized waves (4ft to 4ft) with light winds, but the energy is back to moderate. It’ll be a nice, relaxing session for a change. From Tuesday, July 14th, onwards, it’s back to small, weak, and mostly poor conditions, with a few glassy moments but nothing worth getting too worked up about. The run of good surf is over by then.

So, to sum it up: the first week is a slow build, but the second week has some serious firepower. The absolute best call is Saturday, July 11th morning at Tainohama. If you’re an expert, that’s the one. Sunday, July 12th, is a close second for the experienced lot.

Rusty.

Information about the Tainohama Surf forecast

The above surf forecast table for Tainohama provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Tainohama can be found by selecting the local surf guide option on the grey menu. Our Tainohama 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 (Tainohama) 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 Tainohama 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.

Tainohama is 21 km (13 miles) from Anan. If you plan a holiday in Shikoku, look for hotels and other accommodation in Anan. Anan has rooms for a wide range of budgets as well as car hire and transport links.
