The Lowdown
Hey, Rusty here. Let's cut to the chase – the next week or so is looking pretty ordinary, with tiny waves and weak energy. The swell energy is usually between 32 and 84 (moderate combined energy), so don't expect much.
The first real highlight is on Saturday, July 25th. We've got a long-period groundswell coming in at 16 seconds, which is a proper groundswell. That means better-shaped waves, more energy, and longer gaps between sets – easier paddling. The morning is glassy, which is a beauty, and the swell is small at 1 ft. It's coming from the SE, which isn't the ideal direction for Osaki Point (they want SSE), but with glassy conditions and that long period, it's the cleanest option you'll see all week. The water temp is about average for this time of year.
Then things get wild. On Monday, July 27th, a big pulse of swell hits. The morning sees 7 ft surf from the SE with a 15-second period, and the combined energy jumps to 1727 (strong wave energy). That afternoon, it's 10 ft with an energy of 3811 (very strong). This is expert-only territory – over 8 ft, it's too big for most. The problem is the wind. It's onshore and cross-onshore, making it lumpy and choppy. At a beach-and-reef setup like Osaki Point, with that much swell and poor wind, this is shaping up to be more of a kite-surfing session than a paddle-surfing one.
Tuesday, July 28th is the peak, with 13 ft surf and energy readings of 7064 and 7770 (very strong). The wind is howling from the east at 12 mph, cross-onshore and choppy. This is big, raw, and dangerous. After that, the wind cranks up to 22 to 47 mph from the 29th to the 30th, blowing it completely out. The second week from the 30th onward is a total loss with storm-force winds and tiny, confused swell.
So, the only real standout is the glassy, long-period groundswell on the 25th for a clean, small-wave session. The rest is either massive and messy or flat and blown out. Keep your eyes on the forecast, but don't get your hopes up for the second week.
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.
