Alright folks, Rusty here. Let’s get into it.

We’ve got one main spot lighting up the maps for the next couple of weeks – Osaki Point. This is a beach and reef set-up that’s exposed to the south, so it’s going to be a bit of a rollercoaster ride. Let’s start with the good news.

The water’s sitting at 77°, which is a bit colder than we’d expect for this time of year, so you might want a slightly thicker suit for this first session.

The real fireworks start on Thursday, 10 July. Thursday morning is a little tricky with a cross-on breeze, but the swell is building. It’s Thursday afternoon that gets my heart pumping. We’re looking at a solid 13 ft south swell with a 16-second period. That’s proper groundswell energy, and the combined energy reading is a massive 8541 – that’s some serious power in the water. The wind is light and cross-shore, so it won’t be totally clean, but the size and period will make for some long, hollow walls. This is expert territory, no doubt about it.

Then Saturday, 11 July, is the standout. The morning has a 15 ft SSW swell at 17 seconds, and by the afternoon, it’s hitting 16 ft at 18 seconds. The combined energy peaks at 14280. The wind swings cross-off, and the report says it’s clean. This is about as good as it gets for big wave surfers. The long period means the sets will be widely spaced, but the shape and power will be world-class. This is the one to circle on the calendar.

Sunday, 12 July, holds a 13 ft SSW swell, but it’s a bit smaller. The morning is glassy with light offshore winds, so it’ll be clean. It’s still big, but manageable for experienced surfers.

After that, the swell drops off quickly. Monday, 13 July, has a 6 ft SSW swell with clean offshore winds, a nice session for the intermediate crew. By Tuesday, 14 July, we’re into 5 ft and glassy conditions – a mellow morning.

There’s a significant gap in the good stuff from Wednesday, 15 July, all the way through until Monday, 20 July. The swell is tiny, mostly under 3 ft, with weak energy. It’s surfable, but not worth paddling out for.

Now, here’s the second pulse. On Monday, 20 July, the swell bumps back up. The afternoon brings an 8 ft ESE swell with a 12-second period, combined energy of 3752. The wind is clean cross-off, making it an excellent option for experienced surfers. Then Tuesday, 21 July, is the peak of this second run. The afternoon has a 16 ft SE swell at 14 seconds, with a combined energy of 10703. The wind is light and cross-off, keeping it clean. This is another big-wave day for experts only.

Wednesday, 22 July, keeps the size with an 12 ft SSE swell, glassy morning winds, and clean conditions. The energy is still high, so expect more heavy, powerful waves. This pattern holds through to the end of the forecast on 24 July, with solid 8 ft to 13 ft swells, mostly clean, and glassy mornings.

To wrap it up, the absolute best of the best is Saturday, 11 July afternoon – that 16 ft SSW swell at 18 seconds with clean cross-off winds is a once-in-a-blue-moon event for the experts. The second standout is Tuesday, 21 July afternoon, with another 16 ft SE swell and clean conditions. If you’re an experienced surfer, those are your two targets. For the rest of us, the mornings of 12 July, 13 July, and 22 July offer solid, clean waves without the life-threatening size.

Stay safe out there, and remember, a big swell is a privilege, not a right.

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.
