Alright, surfers, Rusty here with a look at what we’ve got coming up.
Things are shaping up for a serious session if you’re an experienced surfer. For the most part, this is expert territory, so if you’re just starting out, maybe sit this one out.
The big news is a massive, long-period groundswell set to hit this weekend. We’re talking Saturday morning a solid 15 ft swell from the south with a very long 17-second period, packing strong wave energy (11977). The water’s a touch cooler than usual at 77°. Saturday morning has some cross-shore bumps, but the real standout is Saturday afternoon. The wind swings cross-offshore, the sun comes out, and the waves clean right up. That is your best window for Osaki Point. It’s an exposed spot that gets consistent swell, so you can expect it to be on. It’s not a secret spot, so expect the crowd to be there.
Sunday follows up with another cracking day. Morning glass-off with offshore winds and a 13 ft south-southwest swell at 16 seconds. That is exceptional, powerful surfing for experts only. The energy is still very strong (8170). Sunday afternoon drops a little but stays clean and excellent for experienced surfers.
Monday sees the swell drop to a more manageable 7 ft, and we get glassy conditions in the morning. The period is still a solid 12 seconds. The wave energy is moderate (1142), and conditions are excellent for experienced surfers.
After that, the swell fades through the week. Tuesday morning is small at 4 ft, but dead glassy – a good chance for a more relaxed, clean session on the smaller waves. From Wednesday onward through the end of next week, the surf is tiny and ordinary, with poor conditions and onshore winds. There’s a real dead spell for several days there.
But keep the fire stoked for the following week. Around the 22nd and 23rd of July, we see a new pulse of groundswell. Wednesday the 22nd morning is looking promising again, with a 4 ft swell from the east-southeast with a very long 16-second period and glassy conditions. The energy picks back up (883). That’s a good one to circle on your calendar, but it’s a long way out, so don’t book your flights just yet.
Stay safe, read the conditions, and enjoy it when it comes.
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.
