The Lowdown
Alright, let’s have a look at what’s happening at Osaki Point over the next couple of weeks. This spot is a beach and reef setup, exposed to the swell, and the ideal direction is from the SSE.
The first week or so is pretty flat and quiet. Starting Thursday the 16th through to the morning of Sunday the 26th, it’s all small, ordinary conditions. You’ll get waist-high or smaller waves from the SSW or east, with weak to moderate energy (105 to 243). A couple of mornings, like Friday the 17th and Tuesday the 21st, turn glassy, which would be nice for a clean surface, but the waves themselves are tiny. The water temp is about normal for this time of year.
The real action shows up at the tail end. On Tuesday the 28th and Wednesday the 29th, a solid groundswell rolls in from the south and SSW. Swell heights hit 8ft to 10ft with a long period of 13-14 seconds, and the energy is strong to very strong (2690 to 3852). That’s expert territory – not for beginners. The wind on Tuesday afternoon and Wednesday goes cross-offshore or light offshore, so the faces should be clean and powerful. The standout is Wednesday morning with that 10ft SSW swell at 14 seconds and cross-offshore breeze – that’s the one to circle on the calendar.
Crowds happen sometimes here, so expect a few heads out for that swell. It’s a consistent spot when it gets good.
Monday the 27th is windy and choppy, poor conditions. And by Thursday the 30th, the swell drops off again and gets a bit lumpy.
Bottom line: it’s a slow run until the very end of July, but those last couple of days look like a proper payoff for experienced surfers.

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.
