Alright folks, Rusty here. Let’s take a look at what’s cookin’ for the next couple of weeks.
First up, the water temp is sittin' around 79°, which is about average for the time of year, so no surprises there.
The first few days are a bit of a slow start, nothin' to write home about. We’ve got a pulse of swell comin’ through on Monday afternoon, July 13th, with waves around 6 ft from the SSW, but there’s a cross-on wind, and the forecast says it’s marginal. Tuesday, July 14th, shapes up a bit better. The morning is glassy at Osaki Point, with a clean 4 ft SSW swell and moderate wave energy (344). The afternoon cleans up nicely with a cross-off breeze and 4 ft waves (290). That’s about as good as it gets for the first week.
After that, it fades fast. Wednesday, July 15th, offers small, clean waves, but they’re under 3 ft and weak. From Thursday, July 16th, right through to Sunday, July 26th, it’s a real dry spell. The swell drops off, winds turn messy, and most days are rated as poor. There’s a stretch of nearly a week and a half where there’s just nothin' worth paddlin' out for. You’ll see a few knee-high blips with clean winds, but they’re ordinary.
Now, hold onto your board, because things start to look interesting again on Monday, July 27th. A proper pulse of energy arrives, with combined wave energy crankin' up to 1101. You’ll see 6 ft to 7 ft from the SSE with a long period of 13 to 12 seconds – that’s groundswell. This is the standout. That long period groundswell is ideal for a point and reef setup like Osaki Point, where it’ll connect and hold shape. The catch is the wind is cross-on, so it’s not gonna be perfect, but for size and power, that’s the best on offer. The followin' Tuesday, July 28th, still has a solid 5 ft from the S, but the wind goes onshore, and the energy tapers back to moderate (586). It’s not a total washout, but the earlier day is the one to aim for.
So, to sum it up: the first week is a dud with one decent morning on the 14th. The real highlight, the one you want to circle on the calendar, is Monday, July 27th. It’s a long way out, so don’t lock it in yet, but that’s the one with the most grunt.
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.
