The Lowdown
Alright, grab a coffee or a beer, and let’s paddle through what’s on the table for Osaki Point. I’ve looked over the numbers, and mate, it’s a mixed bag—like waiting for a train that might show up but has no schedule. We’ve got a solid 16-day window ahead, but the early part? Honestly, it’s a bit of a flat spell with some ordinary conditions. Then, there’s a real heater brewing for the first week of August, but it comes with a warning label for the big boys only.
Right now, starting Wednesday, July 29, the surf is small and underwhelming. We’re looking at tiny 1.3ft to 1.6ft swells coming from the ESE, with a short period of just 10 seconds. The combined swell energy is weak, sitting between 84 and 95 (units). Winds are light offshore (WSW), which is nice, but there’s a chance of thunderstorms. The water temp is a touch warmer than normal at 28.7°, a touch above average. For a beginner, this is flat; for anyone else, it’s a longboard or a paddleboard day. Not much to get excited about.
Thursday, July 30, the swell drops further to 1.3ft from the ESE, with a period of 9-10 seconds. The energy is even weaker—down to 58 (units) in the morning. But, the wind goes glassy in the morning—dead calm from the south. That’s a major positive for cleanliness. The afternoon mixes up with a light cross-offshore breeze. Still, the waves are tiny, clean, but not surfable for a proper session. This is the definition of *surfable waves but very ordinary conditions*.
Friday, July 31, through Saturday, August 1, the trend continues—weak, small swell. The swell height dips to 1.0ft on Friday, with a long period of 12 seconds. That’s a bit of a tease because long-period groundswell usually means better shape, but at 1.0ft? It’ll be like trying to ride a ripple. Crowds are possible here (sometimes crowded), but with these conditions, it’ll be quiet. The combined energy drops into the 30-50 range—very weak. On Saturday morning, we get glassy conditions again, but it’s all a bit dead.
Sunday, August 2, things start to change. We get a pulse of energy: swell jumps to 2.0ft in the morning, with a moderate 15-second period, and the energy

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.
