The Lowdown
Alright, grab your board. Rusty here, and I'm staring at the charts for Osaki Point for the next couple of weeks. It's a bit of a slow burn at the start, but holy moly, it turns into something special.
First up, the water temp is sitting at 83°F, which is a touch warmer than usual for this time of year. Not a huge deal, just a little extra tropical feel.
The first few days are a bit of a write-off. We're looking at tiny, weak swell through Tuesday the 22nd and Wednesday the 23rd, with just a hint of energy. The combined energy is pathetic, barely cracking 70. It's surfable if you're desperate, but it's not going to get the heart pumping. There's a long gap of nothing much until we see some life.
Things start to get a pulse on Saturday the 26th. The morning brings a glassy 2 ft from the south with combined energy jumping to 222. It's still small, but it's a start. Sunday the 27th is better, with the morning glassing off at 3 ft and the energy climbing to 295. It's clean, but still pretty average.
Now, the real standout is a massive run of swell starting on Monday the 29th of July. That morning, we get a clean 6 ft from the SSW with a period of 11 seconds – that's proper groundswell, boys. The combined energy is huge at 943. This is a paddler's dream with light offshore wind. The afternoon gets a bit sloppy with a cross-off breeze, but the morning is pure gold.
The 30th of July Thursday morning is another stunner: 6 ft, offshore, glassy. But the real highlight is the Thursday afternoon. The swell jumps to 7 ft from the SSW, a moderate offshore wind, and the combined energy rips at 1213. This is excellent surf for experienced surfers only. This is the one you call in sick for.
The action keeps rolling into the first week of August. The morning of Saturday the 1st looks glassy with 4 ft, but the afternoon on the 2nd of August is a monster. 8 ft from the SSE, a 16-second period, and combined energy of 3446. That's a serious, powerful, very long-period groundswell. It's going to be a freight train, and it's only for the experts. The best on offer is the 3rd of August, Monday. The morning shows 10 ft from the south, a 15-second period, and a combined energy of 5633. The afternoon is even bigger: 12 ft from the south, 16-second period, and a combined energy of 6902. This is exceptional, dangerous surf. If you're not a pro, stay on the beach and watch.
The spot is a beach and reef setup, so with those long-period swells, it's going to be a bit straight and dumpy on the beach, but the reef will be firing. It's exposed, so it will catch everything. Crowds are listed as "sometimes", but with a run like this, you can bet it'll be busy.
So, to wrap it up: the first week is a dud. The absolute standouts are the 29th of July morning for a solid, clean day, and the 3rd of August for the massive, expert-level swell. The 2nd of August afternoon is also a massive, expert-level highlight. Don't waste your time before the 26th.
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.
