The Lowdown
Alright, Rusty here. Let’s have a look at the charts for the next couple of weeks.
Honestly, the first week is a total write-off. We’re looking at a long dry spell from now until the 26th of July. The swell is tiny, with wave heights barely scraping 2ft at best, and the energy is weak, sitting at only 91. The conditions are ordinary, with a bit of a glassy window on Friday morning, but it’s just not enough to get excited about. You’d be better off cleaning the wax off your board and waiting.
The real story starts to shift on Sunday the 26th of July. That morning we see a pulse of 4ft swell from the SE, with a very long period of 18 seconds. The energy jumps to 507 (moderate), and the wind is light and offshore from the ENE. This is a groundswell, and with that period, it’s going to be juicey and lined up, but at a beach and reef setup like Osaki Point, it might break a bit straight. It’s a promising start, but the real standout is a few days later.
The standout is the 29th of July, Wednesday morning. This is the one to circle. We’ve got a solid 20ft swell from the SSW, with a period of 14 seconds. The energy is absolutely pumping at 13,984 (very strong). The wind is a clean, cross-offshore breeze from the south at 15 mph. This is big, powerful, and clean. There will be long lulls between sets, but the waves that come through will be proper. With the swell over 8ft, this is for experienced surfers only. The break is consistent, and while crowds are sometimes an issue, the quality of the surf should thin the pack out a bit. The water temperature is 82°F, which is about normal for the time of year, so you’ll be fine in boardshorts.
The swell hangs around through the 30th, with 18ft from the SSW and clean conditions, but the energy starts to drop. By the 31st, it’s down to 8ft but still clean, making for a solid Friday morning session for the more experienced crew.
After that, it fades out into the first week of August with nothing much to report. So, get your rest now, because the end of the month is going to be a ripper.
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.
