The Lowdown
Alright, Rusty here, lookin' at the charts for the next couple of weeks. Let's be real, it's a bit of a slow patch for the most part, but there are a couple of windows that could be alright if you're patient.
Right now, we're kickin' things off on Wednesday, 15 July, with a bit of a weak start. The water temp is sittin' at 79°, which is normal for the time of year, so no worries there. The swell is a weak 3 ft from the SSW, with a combined energy of only 159 (weak). It's pretty ordinary, and the wind is onshore, so it's not great. The first solid session pops up Wednesday afternoon though – a 4 ft SSW swell with a short 8-second period, but the wind goes offshore. That's a clean look at Osaki Point (beach and reef). The energy bumps up to 265 (moderate), but the swell is small and short. Still, it's your best bet for the first few days.
Thursday morning stays marginal, with a 4 ft swell but cross-shore wind messing it up. Thursday afternoon it drops off. The rest of the week into the weekend is flat, with tiny 2 ft to 2 ft lumps and mostly cross-off or glassy conditions. It's surfable but very ordinary – you'll be on a longboard if anything.
The real standout that's got my attention is Saturday, 25 July. That morning we see a jump in swell to 5 ft from the SW, with a short period again, but the wind is glassy. The combined energy hits 299 (moderate), which is the best energy we've seen. It's still only 5 ft, so it's fine for everyone, and the glassy conditions will make it clean. That morning session is the pick of the whole forecast. The afternoon holds up alright too with a cross-off wind.
Sunday the 26th morning is also a looker – 4 ft from the SSW with glassy winds again, energy at 272 (moderate). That's a solid second option. After that, Monday the 27th has some clean 3 ft southeast swell with cross-off wind in the morning, but the afternoon gets a bit cross-shore.
The second week gets a bit messy. The 28th and 29th of July have some size around 3 ft to 4 ft, but the wind is up and there's risk of thunderstorms, so it's choppy. Not worth paddling out for. The 30th sees a small drop, with 3 ft from the south and offshore wind, so it's clean but tiny.
Overall, don't get too excited for the first two weeks. The best windows are Saturday the 25th and Sunday the 26th mornings. If you can get out then, you'll find some clean, fun waves. The rest of the time, it's a waiting game.
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.
