Table - best surf conditions forecast for Osaki Point over the next 16 days.
Alright, let’s talk about Osaki Point for the next couple of weeks.
We’ve got a proper pulse of groundswell coming in, but it’s gonna take a few days to line up. The real standout window is from Friday, July 10th, through Sunday, July 12th. That’s where the magic happens. The combined energy is massive – over 13,000 on Friday afternoon – with a 4.5m swell from the S at a 17-second period. That is a serious, long-period groundswell. For a beach and reef setup, that long period can make it a bit straight on the beach, but the reef will handle it beautifully. It’s big, though – over 8 feet, so this is expert-only territory.
Saturday the 11th holds that size, still 4.5m (15 feet) with a 17-second period, but the wind is more cross-shore. The energy is still pumping (over 11,000). Then Sunday the 12th is the real gem. Morning glass-off with a light offshore from the SW, swell dropping to a still-chunky 3.5m (12 feet) from the SSW at 16 seconds, and the conditions are clean. That’s the pick of the window for anyone who knows what they’re doing.
After that, it drops right off. Monday the 13th has a bit of leftover swell, around 1.2m to 1.6m (4 to 5 feet), with glassy conditions in the morning – perfect for a relaxed session on a longboard. The water temp is about average for this time of year, so no surprises.
Tuesday the 14th is small, and then we get a few small pulses through the middle of the week, but nothing to get excited about. The second week shows a few days with clean conditions and waist-high waves, but the energy is low (under 700). Friday the 17th sees a little bump back up to 2.0m (7 feet) from the S with a 12-second period and clean cross-offshore winds – that’s a decent little window for experienced surfers, but it’s not the same beast as that first weekend.
The last few days of the outlook, from the 20th onward, are pretty poor. Strong winds on the 20th (40 km/h) make it a write-off, and the swell fades into tiny, weak leftovers. Not worth paddling for.
If you’re chasing the best, it’s all about that Friday to Sunday run, with Sunday morning the absolute standout. Clean, offshore, solid groundswell – that’s the one.

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.
