Alright, let's get into it. This is Rusty, bringing you the goods for Osaki Point.
Alright, so the next couple of days are pretty quiet, but don't let that fool you. There's a serious pulse of energy working its way in. We're looking at a bit of a slow start, but Wednesday the 10th of July is where you need to be looking.
Right now, from Friday the 3rd through to Monday the 6th of July, it's mostly small and ordinary. You'll see a few waves around 2ft to 4ft, but the energy is weak (65) and conditions are just average. There's a brief moment Sunday morning the 5th with glassy conditions and a 4ft swell from the SSW, but it's nothing to write home about.
Then things start to build. Monday the 6th afternoon brings a sudden jump in period to 14 seconds on a 3ft SE swell, and the energy hits 373. That's a sign of things to come. Tuesday the 7th gets bigger, but the wind is messy. By Wednesday the 8th, we're looking at a solid 10ft swell from the SSE, and the energy is massive (4248). This is big, powerful groundswell (16-18 second periods) but the wind is light cross-onshore, so it'll be lumpy. This is expert territory.
Now, here's the standout. Friday the 10th of July. Morning session is going to be absolutely firing. We've got a 13ft swell from the S, pumping through with a very long 17-second period. The energy reading is a massive 8677. The wind is glassy, dead calm. This is the kind of day that lives in memory. The water temp is 77°F, which is about average for this time of year, so the rubber is staying in the shed. This is for expert surfers only; that's a heavy, powerful wave. The swell direction is S, and the optimum for this spot is SSE, so it's a good match but be ready for some serious power.
Saturday the 11th of July holds onto that 13ft, but the wind goes offshore (WSW) in the morning, making it clean. Another exceptional day but still for experienced crew only.
After that peak, it settles down. Sunday the 12th is still excellent for experienced surfers with an 8ft swell and clean offshore winds. Things taper off through the week, with fun but smaller waves from the 13th to the 14th of July. By the 15th, the wind picks up and the swell drops out. The last recommendation is on Saturday the 18th of July, with a tiny 2ft wave and clean conditions, but it's really just a sign that the ocean is taking a breather.
So, if you're an expert, lock in Friday the 10th and Saturday the 11th of July. That's the best of it.

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.
