Alright, Rusty here again. Let's break down what's cooking at Osaki Point over the next couple of weeks. It's a beach-and-reef setup, consistent, and exposed to swell, with the best direction being from the SSE. Water temp is about normal for this time of year.
Sunday the 5th is a total loss – tiny, weak, messy. Combined energy is only 154 (weak). No point even looking.
Monday the 6th morning gives us the first real sniff. Swell is small at 2 ft, but it's from the SE with a very long 16-second period – proper groundswell. Wind is offshore from the SW at 9 mph. Combined energy is 263 (moderate) and it's clean. Small but rideable for intermediates. The afternoon bumps to 3 ft, 14-second period, still offshore from the WSW. Combined energy hits 555 (moderate). Getting better.
Tuesday the 7th is a standout. Morning is glassy – 3 mph from the SSE, 4 ft SE swell at 12 seconds. Combined energy is 819 (moderate). Perfect clean conditions. Afternoon sees 5 ft SE swell, 16-second period, cross-off wind. Combined energy is 1471 (strong). Excellent for experienced surfers.
Wednesday the 8th is the big one. Morning glassy again, with 10 ft SE swell at 17 seconds. Combined energy is 4939 (strong). That's serious power. Afternoon holds at 10 ft, shifting slightly to SSE, still 16 seconds, with a cross-off breeze. Combined energy is 5402 (strong). Exceptional but for experts only – over 8 ft is too much for beginners. The long period means better shape but heavier sets.
Thursday the 9th and Friday the 10th keep the swell going – 10 ft to 16 ft – but wind turns onshore or cross-on. Combined energies are massive – 5837 to 13889 (very strong). Marginal conditions, but there could be something for the die-hards.
Saturday the 11th afternoon is another highlight. 15 ft SSW swell, 17-second period, cross-off wind. Combined energy is 11452 (very strong). Clean and powerful, for experts only.
Sunday the 12th morning still has 10 ft SSW groundswell, glassy, with 2974 combined energy (strong) – good for experienced surfers. But it fades after that.
From Monday the 13th through Sunday the 19th, it's a long dry spell. Small, weak, onshore winds, poor conditions. Combined energies mostly under 500 (weak). A little bump on the 18th morning to 6 ft, but it's onshore and messy.
Best windows: Tuesday the 7th and Wednesday the 8th for clean, building swell. And Saturday the 11th afternoon for a big, clean groundswell for experts. After that, a week of flatness. Keep the board waxed and wait for the next pulse.
Rusty.

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.
