The Lowdown

Right, folks, Rusty here. Let's talk about the 16-day stretch at Osaki Point. It's a bit of a mixed bag for this beach-and-reef setup, but there's a couple of real sweet spots to get excited about.

For the first week, the news is rough. Wednesday the 2nd through to Monday the 7th is a write-off. We're looking at a solid 5-day gap with no worthwhile surf. The wind is mostly cross-onshore, often strong, and the sea state is just messy. You'll see the swell size bumping up to 13ft, but the combined energy is strong and it's just blown out junk. Not worth a paddle.

Now, the first standout window arrives on Tuesday the 8th. The morning session is the pick of the early run. There's a solid 13ft swell from the ESE, with a period of 11 seconds, packing strong energy. The magic is the wind: a light NW cross-off, just 3 mph, keeping the surface clean. This is for experienced surfers only, as that size is well over the 8ft mark. Crowds are a possibility at Osaki Point, so get out early.

The next real highlight is a few days later. Thursday the 10th is looking prime. The morning session is glassy, with a 6ft ESE swell, moderate energy, and clean conditions. The afternoon is even better with a 7ft ESE swell, period of 11 seconds. The wind is glassy from the ENE, just 3 mph. That's a beautiful, clean window for intermediate surfers.

Looking further ahead, the second week gets interesting but a bit wild. On Tuesday the 15th, the model shows a massive 16ft ESE swell with a 14-second period and colossal energy. The wind is a strong cross-shore, so it's messy and basically too big for the break. After that, the quality improves. Wednesday the 16th afternoon delivers a clean 8ft ESE swell (11-second period) with a light cross-off wind. Thursday the 17th morning is the real sleeper, though: a clean 5ft ESE swell with a 10-second period and glassy, calm conditions. That's a perfect morning for a longboard.

So, to sum it up: the first week is a washout, but get on the water Tuesday the 8th morning for a big one, and circle Thursday the 10th for the best all-round conditions. The long-range window on the 16th and 17th looks promising, but it's a bit less certain this far out.

Stay stoked, and keep your eyes on the horizon.

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.
