Alright folks, Rusty here with a look at the upcoming surf. The first wave action on offer kicks off Monday morning, July 13th, at Osaki Point. This is a beach and reef set-up, and it’s exposed to the swell. The rest of the week after that initial pulse gets pretty slim, so let's break it down.

We start with a proper pulse of energy Monday morning, the 13th. The ocean is pumping with a combined swell energy reading of 1151, so there’s plenty of power in the water. We’re looking at a solid 7ft swell rolling in from the SSW with a lovely 12-second period – that’s quality groundswell. What makes this a standout is the glassy conditions; the wind is dead calm, 0 mph from the SW. It doesn’t get any cleaner than that for an exposed point. The water temp is 78°, which feels a bit colder than normal for this time of year (about 2° off the average), so you might want a thin spring suit. This setup is excellent, but at 7ft, it’s really for the experienced crew only.

Monday afternoon the wind swings ESE at 3 mph, putting us in a light cross-onshore. The swell drops to 6ft from the same SSW direction, energy down to 725. It’s still surfable, but that morning glass was the pick. Tuesday, the 14th, sees the swell dropping fast to 4ft and 4ft through the day with that cross-onshore wind, making it pretty ordinary. Wednesday the 15th is tiny, with only 3ft waves and weak energy, though the morning does go glassy again – at least it’s pretty, but barely worth a paddle.

Thursday the 16th through to the end of the week is a write-off. The swell gets smaller, the period drops short (7-9 seconds), and energy stays below 200. Most of it is marked as poor surf conditions. There’s a long gap with nothing worth recommending through to late July.

Now, looking further ahead, things get interesting again. On Tuesday, July 21st, we see the energy ramping back up. The morning is glassy with a 3ft swell from the ESE, 10-second period, and the energy is building to 220. It’s a promising sign. The real standout, however, looks to be Wednesday, July 22nd. The morning kicks off with clean 4ft swell from the East, a long 12-second period, and glassy winds from the ENE at 3 mph. The combined energy is a healthy 573 in the morning, rising to 603 by the afternoon. The swell direction (E) is a better match for the optimum (SSE) than we’ve seen, and with glassy conditions all day, this is the one to circle on the calendar. It’s still a week and a half out, so treat it as promising but not locked in just yet.

After that, things taper off again. Thursday the 23rd has marginal conditions, and the following days drop back to tiny, weak surf with very long period swells (15-16 seconds) that are better suited to points and reefs than this exposed beach and reef set-up. There is a spike in energy on the 27th and 28th of July – Monday and Tuesday – with 7ft swell from the S and SSW, and very strong energy readings over 1000. The Tuesday morning on the 28th looks glassy again, which is a fantastic sign for another big day for the experienced crew. But we’re talking two weeks out, so take that with a grain of salt for now.

So, the bottom line: The absolute best of the bunch is Monday morning, July 13th, for those with the skills to handle a clean 7ft groundswell with glassy conditions at Osaki Point. The second standout is the promising run on Wednesday, July 22nd – another glassy day with solid 4ft easterly swell. Do not waste your time on the flat days in between.

Stay stoked, and I’ll see you in the water.

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.
