The Lowdown

Alright, let's get into it. The long-range picture for Osaki Point is a tough one, plain and simple. We've got a real dry spell on the horizon for the most part. The first proper chance of anything decent is a long way off, and even then, it's not exactly firing.

We're looking at a couple of weeks where the onshore winds and lumpy conditions are the main story. Early on, like this Friday and into the weekend, the swell is there, but it's messy. Watch out for that big jump on Sunday the 6th with swell pushing 10ft to 11.5ft, but with fresh cross-onshore winds and heavy rain, it's gonna be a washing machine out there. That's not surf for the faint of heart, and honestly, it's not looking like a fun paddle. The energy readings are high, over 2500 on that Sunday afternoon, but it's all that raw, unrefined stuff. With that size and the wind, this might be a better session for the kite crew than the surfers.

The days following just fade away. There are small windows here and there, but the swell direction swings around and the period is a bit short, so the shape won't be there. The wind is mostly cross-shore, which keeps it choppy. It's a real grind.

The standout, and I'm using that word loosely, looks to be the morning of Sunday, the 13th of September. It's a small one, only 2ft, but it's coming from the E at a long 14 seconds. That's a bit of proper groundswell. Most importantly, the wind is glassy, dead calm. The energy is weak, at 206, but you won't care about that when you're getting a few clean ones. It'll be a longboard session, but that's a far cry from the slop we've had. It's all about the conditions.

A bit further out, the morning of the 17th of September also looks glassy, with small 2.3ft waves at 8 seconds. The energy is really dropping off by then, down to 107, which shows just how weak it is. For a spot like this, that's super marginal, but if you're desperate, it might be the only other clean-ish window. We just need that wind to stay light and the swell to hold in any kind of shape.

This is a long stretch of nothing much. The near-term calls aren't working out, and the long-range stuff is just promising, not guaranteed. Don't hold your breath, but keep an eye on that glassy morning on the 13th.

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.
