Alright, let's get into it. The surf forecast for Osaki Point kicks off with a slow start. There's a bit of swell on Sunday the 5th of July, but with heavy rain, light cross-shore wind, and only 3ft of weak, short-period swell (combined energy 69), it's a write-off. You're better off staying dry. The first real glimmer of hope comes on Monday the 6th of July. The morning brings a jump in quality with a clean, 2ft swell from the SE, but it's the afternoon that gets the nod: a 3ft, 14-second groundswell from the SE with a gentle offshore wind from the WSW and clean conditions. The combined energy climbs to 324, so it's moderate, but it's a decent reintroduction after a flat spell.
Tuesday the 7th of July sees a mix. The morning has a 5ft ESE swell, but with a light cross-onshore wind, it's a bit bumpy. The afternoon is better, with a 4ft, 16-second long-period SE swell and a combined energy of 1068, but still a cross-onshore breeze. It's surfable, but not the stand-out.
Now, the real story starts Wednesday the 8th of July. The swell builds rapidly. By Wednesday morning, we're looking at an 8ft, 18-second very long-period SE swell, with a combined energy of 4108. That's a lot of power. It's a cross-onshore wind, but the energy is undeniable. This is expert territory. By Wednesday afternoon, it's 10ft, 17 seconds, and the energy jumps to 4719. This pattern holds through Thursday and Friday. Thursday the 9th of July sees 10ft swells all day, with the combined energy hitting 6907 by the afternoon. Friday the 10th of July is when it really goes off. The morning has a 13ft, 17-second S swell and a combined energy of 8228. The afternoon is massive: 13ft, 17-second S swell with a combined energy of 12153. This is strong, serious wave energy. The wind is a light cross-onshore, so it's a bit bumpy, but for big-wave hunters, this is the window.
Then comes Saturday the 11th of July. The morning is the absolute standout. A 15ft, 17-second SSW groundswell, with the combined energy at 11613, and it's glassy. Glassy. Offshore wind from the WNW. This is exceptional surf for expert surfers. The sets will be big, with long gaps between them, making it easier to paddle out, but the wave height is in the 15ft range, so this is for experts only. The afternoon stays big, but the wind goes cross-shore, so the morning is the pick.
Sunday the 12th of July is still pumping, but the swell drops to 10ft. The morning is glassy again, with a 14-second SSW swell and a combined energy of 3764. Excellent conditions for experienced surfers. The afternoon has a 8ft, 14-second swell with a clean cross-offshore wind. Good, but not as good as Saturday.
From Monday the 13th of July, the swell steadily drops. Monday morning is glassy with a 5ft SSW swell, and the afternoon is clean. It's a nice, manageable size for intermediates. The rest of the week into the weekend looks inconsistent. The swell drops to 4ft on Tuesday the 14th, and the wind gets messy. Wednesday the 15th of July is small and weak. By Thursday the 16th, the swell picks up a bit to 6ft, but it's a short-period 8-second ESE swell, so it's going to be weak and choppy. The combined energy is only 762. The following week, from the 17th of July onwards, the forecast is poor. Small, weak swells, onshore winds, and rain. The water temperature is about 77°, which is normal for the time of year.
So, the one true standout is the Saturday morning session on the 11th of July at Osaki Point. Big, glassy, and powerful. The Friday the 10th afternoon is a close second for the sheer size and energy, but the wind isn't as clean. The rest of the first week has plenty of size for experienced surfers, but the wind is a constant cross-onshore, keeping it from being perfect. After the 12th, it's a slow fade to small, messy conditions.

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.
