The Lowdown
Alright, let's get into it. This is Rusty, and I’m looking at the next couple of weeks around Osaki Point.
Right off the bat, we’ve got a pretty quiet start. The first few days here are all about small, weak waves, and honestly, not much to write home about. The real action doesn't show up until later.
We kick things off on Wednesday the 15th with a tiny 3ft SSW swell. The energy is weak (159), but the wind is glassy from the east in the morning, so it’s clean. The water is a warm 79°, which is pretty normal for this time of year. It’s surfable, but you’ll be hunting for the little ones. Wednesday afternoon cleans up with a light cross-offshore breeze, and the swell bumps up to 3ft, still nothing special.
Thursday the 16th is a bit of a write-off. The wind turns cross-on, and the swell is messy with a short period. Friday and the weekend are similar – small, weak, and mostly onshore or cross. The energy drops into the double digits, and the waves are barely breaking. It’s a stretch of flat, forgettable days.
There’s a little glimmer on Monday the 20th and Tuesday the 21st. The swell is still tiny, around 2ft, but the wind goes glassy or offshore, and the period stretches out a bit. It’s clean, but you’ll need a longboard and a lot of patience. The energy is still very weak, just over 70 (84 on Monday afternoon). Not a standout, just a chance to get wet.
Now, here’s where it gets interesting. The real standout is locked in for Saturday the 25th. The morning brings a clean, glassy start with a 5ft SW swell. The energy jumps to 281 (moderate), and the wind is dead calm. This is the best-looking window in the first week. The swell direction is SSW, and the optimum is SSE, so it’s a bit off-angle, but the quality of the conditions – glassy, clean, and a decent size – makes it the pick of the bunch. The afternoon stays clean with a cross-off breeze.
But the absolute best on offer comes on Monday the 27th. The morning is glassy with a 6ft E swell, and the energy is strong (625). The afternoon is even bigger, hitting 8ft from the east with a clean cross-off wind. The energy is very strong (1116). This is for experienced surfers only – anything over 8ft is a beast. The period is 8 seconds, so it’s a shorter period wind swell, but the size and clean conditions will make for some powerful, hollow waves. This is the day to circle on the calendar.
After that, the wind turns onshore and the swell gets messy. Tuesday the 28th is questionable, with a strong cross-on breeze and a 4ft SSE swell. Wednesday the 29th and Thursday the 30th are big – 8ft to 10ft – but the wind is howling onshore from the ENE and E. The energy is massive (over 2000), but it’s all blown out. This setup is more interesting for the kite surfers than paddle surfers. The period is 13-14 seconds, which is a long period groundswell, but with onshore wind, it’s just a washing machine.
So, to wrap it up: the first week is small and weak. The best window is Saturday the 25th for a clean, fun sized wave. The absolute standout is Monday the 27th for the experienced crew – big, clean, and powerful. The end of the period is windy and messy.
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.
