The Lowdown

G'day, I'm Rusty. Let's have a look at what's coming our way for Osaki Point over the next couple of weeks.

We're in for a rough start, no two ways about it. The first several days are a write-off with poor surf conditions and onshore winds. The water temp is sitting at a touch warmer than normal for this time of year, about 85°, over three degrees above what you'd expect. Thursday the 6th kicks off with a big 16ft SE swell, but it's blown out by a fresh 19 mph onshore breeze. The combined wave energy is a massive 10035, but it's all for nothing – it's a mess. The same story rolls through Friday and Saturday with thunderstorms and onshore winds, surf dropping from 13ft to 8ft, but still no good.

Sunday the 9th is still no good, but the morning gives a hint of life – an 8ft SSW swell with the energy down to 3069. It's labelled marginal, which is generous, but the wind is still on it. Monday stays marginal with smaller 7ft to 7ft SSW swell, and the energy dropping through the 1000s. It's not surfable.

The real window opens on Tuesday the 11th. This is the standout. Tuesday morning, glassy conditions, zero wind, and a clean 6ft SSW groundswell with a period of 12 seconds. The combined energy is 1181. That's solid, clean, and for experienced surfers – it's excellent. The swell is coming from the SSW, matching the optimum direction, and with glassy conditions, it'll be pure. The afternoon stays clean with a light cross-offshore breeze. For a beach and reef setup like Osaki Point, this is the day to be in the water. Crowds are possible here at times, so get in early.

Wednesday the 12th is still very good – clean again in the morning with glassy conditions and a 5ft SSW swell at 11 seconds. Energy is down to 686, but it's clean. The afternoon stays tidy.

Thursday the 13th brings a shift to a 5ft easterly swell at 12 seconds, with glassy conditions in the morning. The energy is 890. It's good, but the direction isn't as ideal as SSW. The afternoon stays clean but becomes marginal.

Then things fall apart again. Friday the 14th through to Wednesday the 19th is a long stretch of poor surf. Heavy rain, thunderstorms, and onshore winds dominate. Swell stays between 4ft and 8ft, but the wind ruins it. The energy values are low to moderate, peaking at 2603, but it's all blown out.

There's a promising end to the outlook. Thursday the 20th – yes, a week after the last good day – morning brings glassy conditions again, with a 5ft easterly swell at 10 seconds and a combined energy of 1030. It's labelled excellent for experienced surfers. The swell direction is E, which isn't the optimum SSE, but with glassy conditions and clean waves, it's a solid option. The afternoon gets a bit choppy, but the morning is a go.

Friday the 21st is marginal with rain showers. So if you're looking at the whole picture, Tuesday the 11th and Thursday the 20th mornings are your best bets. Tuesday is the absolute standout, with glassy conditions and a well-directed SSW groundswell. Don't sleep on it.

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.
