The Lowdown
Alright, this is Rusty. Let's break down what we've got for Osaki Point over the next couple of weeks. It's a beach and reef setup, and the water temp is sitting at 80.8°, pretty much bang on average for this time of year, so nothing weird going on there.
To be honest, the first week and a half is a bit of a write-off. We're looking at small, weak, unexciting waves from the 16th of July all the way through to the 25th. There's a bit of a pulse around the 20th with the combined energy hitting 106 (moderate), but the wind is onshore and the quality is just poor. You'll get a few glassy mornings on the 17th and 21st, but the swell is tiny—like 1.6ft to 2.3ft—and it's mostly wind swell with short periods. It's surfable if you're desperate, but you won't be telling your mates about it. For a good stretch there, from the 18th to the 24th, the energy is mostly under 100 (weak) and the waves are just ordinary. We finally see a proper uptick on the 25th with a long-period SE groundswell—16 seconds—but the height is still only 1.3ft, so while it's clean with offshore wind, it's just not got the size.
Now, hold onto your board, because the end of the month is where it gets interesting. The 26th of July is the first real standout. The swell jumps to 4.3ft from the SE with a 13-second period, and the combined energy is a solid 582 (moderate to strong). The wind goes offshore from the WSW, swinging to the SW, and it's clean. This is a proper session for the intermediate crew; the waves will have some punch and the conditions will be silky.
But the real monster is on the 27th and 28th of July. This is big-boy territory. On the 27th, we're looking at a 9.8ft swell from the SSE with a 14-second period. The energy is off the charts at 3544 (very strong). The wind is offshore and light. This is excellent, but at 9.8ft it's for experienced surfers only—beginners stay well clear. Then the 28th kicks it up a notch: 14.8ft from the S with a 14-second period. The energy is a massive 7394 (very strong). Again, offshore winds. This is exceptional, but it's a serious, heavy wave and strictly for experts. The swell direction from the S is a bit off Osaki's optimum from the SSE, but when it's this size and this clean, you make it work.
After that peak, the 29th still has a solid 6.2ft SW swell with a moderate 11-second period, and the winds stay favourable, so there's plenty of fun to be had for the experienced guys. The energy is still very strong at 1416. Into the 30th and 31st, it drops back down to more manageable 2.0ft to 2.3ft, but the period holds up, and with glassy conditions on the 31st morning from the E with a 13-second period, it'll be a lovely, clean longboard day.
So, to sum it up: the first nine days are barely worth the paddle out. The real action is the last few days of July. The absolute standout is the morning of the 28th—14.8ft, clean, offshore, just a beast for those who can handle it. The 26th afternoon and the 27th and 29th mornings are also excellent, but for the experienced surfer. Crowds are listed as "sometimes" at Osaki, so when a swell like this hits, you can expect a few chargers in the water, especially on the weekend.

Information about the Osaki Point Surf forecast
The above surf forecast table for Osaki Point provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Osaki Point can be found by selecting the local surf guide option on the grey menu. Our Osaki Point 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 (Osaki Point) 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 Osaki Point 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.
Osaki Point is 14 km (9 miles) from Muroto. If you plan a holiday in Shikoku, look for hotels and other accommodation in Muroto. Muroto has rooms for a wide range of budgets as well as car hire and transport links.
