Alright folks, Rusty here, looking at the 16-day run ahead for us. We've got some serious grunt coming in, but it's not for the faint-hearted. Hang on, 'cause we’re looking at a wild start.

The big story here is a massive pulse of swell arriving on Saturday, July 11th and holding through the weekend. It’s not a friendly wave for everyone. On Saturday afternoon, Osaki Point is getting hammered by a solid 15 ft SSW groundswell with a long period of 17 seconds. The wave energy is absolutely pumping at 12304, which is enormous. This is pure, raw power – expert territory only. The wind is a clean cross-off from the SSW, which should keep the faces lined up, but with that much juice, you’re looking at heavy, bowling sections. Water temp is sitting at 78°, which is a bit colder than normal for this time of year, so you might want an extra thin layer.

Sunday, July 12th, isn't letting up much. The morning still has 13 ft of SSW swell, with a 16-second period, and the wind swings to a clean offshore W at 6 mph. It’s still a heavy session, and the energy is still very strong at 7660. The afternoon dips to 12 ft, still grunty, but conditions stay good with offshore wind.

By Monday, July 13th, it starts to settle. The morning has a much more manageable 7 ft SSW swell, with cleaner 12-second period, and it’s glassy with SW wind at just 3 mph. This is where the intermediate crew can start eyeing it. The afternoon gets a bit smaller at 6 ft and remains glassy, but there's a risk of thunderstorms. The wave energy is now moderate around 1132.

After that, the swell fades fast. Tuesday, July 14th is small and clean but weak, with 4 ft dropping to 4 ft. Things actually go pretty flat and poor from Wednesday the 15th right through to Saturday the 19th. We’re talking a solid 5-day stretch of small, onshore junk that you wouldn't bother paddling out for. This is where you fix your dings or just go fishing.

There’s a glimmer of hope on Sunday, July 20th, but it’s stormy and onshore with 8 ft SE swell and a moderate period. It looks more like a mess than a good surf day, honestly.

Now, the second week shapes up much differently. From Monday, July 21st, we finally get some glassy mornings back. Osaki Point on Tuesday the 21st sees clean 4 ft ESE swell and glassy conditions. The swell direction is shifting around, and while the sizes are smaller, the quality should be better for a fun, cruisy session.

The standout in the second week looks like Wednesday, July 22nd. In the afternoon, we get a 4 ft ESE swell, but here’s the kicker – the period jumps to a very long 13 seconds, and it’s a clean cross-off wind from the SW. That long period combined with the right direction should produce some lined-up, punchy waves off the point. The wave energy is a moderate 566, but the quality will be high. The mornings leading into the 23rd and 24th look clean and rideable too, with offshore to cross-off breezes and 4 ft to 5 ft swell. That stretch from the 22nd to the 24th looks like the most consistent and user-friendly run of the whole forecast.

This run just drops off again towards the end. The final call is Saturday, July 25th: absolute glassy conditions, no wind, with 4 ft S swell. A beautiful morning session for a log if you’re keen.

So to sum it up: the absolute peak for power and size is this Saturday and Sunday (July 11-12), but only for the hardcore crew. If you’re looking for the best balance of clean conditions and fun, rideable waves for the average surfer, point your board towards the 21st through the 24th of July.

Stay safe out there, 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.
