The Lowdown
Alright folks, Rusty here. Let’s get into what’s on the table for our little stretch of coast around Osaki Point. It’s a mixed bag, no doubt about it, with a long, flat spell right through the start. The first real taste of anything rideable is a long way off, so patience is the name of the game.
Right now, we’re looking at a pretty quiet run. From Friday the 17th right through to Saturday the 25th of July, it’s mostly tiny, weak surf with a combined energy that rarely gets out of the two-digit range (91 to 138). The swell is hanging around 1 ft to 2 ft, mostly from the east or southeast. The period is short, between 7 and 10 seconds, so the waves that do show up will be soft and mushy. There are a few glassy windows in the mornings (like Friday the 17th and Sunday the 19th) with clean conditions, but honestly, with that lack of height, it’s barely worth paddling out unless you are desperate for a longboard glide.
There is a big gap of several days here where there’s really nothing to recommend. The spot is consistent, but the size just isn't there.
Now, hold onto your board, because things get interesting on Sunday the 26th of July. We finally get some push, with the swell jumping to 5 ft from the SE, a 14-second period, and the combined energy cranking into four digits (1085). That’s the first real sign of life. The problem? The wind is onshore and the conditions are messy, with a risk of thunderstorms. The forecast is only marginal, but it’s a start.
The standout window is looming on Tuesday the 28th of July. We’re looking at a serious pulse of swell, with heights hitting 13 ft to 15 ft from the ESE, a very long 16-second period, and energy readings that are off the charts (7855 to 9671). That’s strong wave energy, no question. The wind is light cross-onshore with small ripples in the afternoon – not perfect, but much better than the days prior. This is expert territory, folks. 13 ft+ is not for the faint of heart, and with that long period, it’s going to jack up fast and put out a lot of power. The crowds will likely be there as it’s a spot that can handle it, but you need to know what you’re doing.
After that big event, things settle down quickly. Wednesday the 29th looks glorious, with the swell dropping to 3 ft from the E, a 12-second period, and glassy conditions in the morning. The combined energy is a manageable 352. This is the cleanest, most user-friendly surf of the whole run. It’s the best chance for intermediates to get a few clean ones.
So, to sum it up: don’t bother for the first week. The real story is the big, dangerous swell on Tuesday the 28th for the experienced crew, but the real pick for a good, clean session is Wednesday the 29th of July. Keep your eyes on the sky.
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.
