The Lowdown
Alright, Rusty here again. Let's break down the coming swell window.
It's a slow start, no doubt. The first few days are flat and small, with barely a ripple worth paddling for. The water’s a touch warmer than we usually see, about 83°, which is nice, but the waves are not.
The first chance of something half-decent arrives around the 25th of July at Osaki Point. We're looking at a small groundswell from the SE, coming in at about 1ft, but with a solid 16-second period. The combined energy is moderate (147), and with glassy conditions that Saturday morning, the surface will be clean. It's tiny, but for a log or a fun board, you could get a few.
The real window, the one you want to keep an eye on, starts on the 28th of July. That Tuesday morning, the swell pumps up to 6ft from the SSW, with a 12-second period and a combined energy of 1180. The wind is offshore from the WSW, which is ideal. This is excellent surf, but at over 6ft, it's for the experienced surfers only. It holds through the afternoon at 7ft, and the offshore breeze picks up a bit. This is the best bit of the forecast. The quality stays high through Wednesday morning with clean, offshore winds.
After that peak, the swell slowly winds down. By the 31st of July, we're still getting solid 5ft to 6ft sets from the SSW, but the period drops, and expect the crowd factor to be high. The first few days of August see it drop right back to small, ordinary conditions, so make sure you get out there during that last week of July.
Rusty out.

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.
