The Lowdown

Alright, Rusty here. Let’s have a look at what’s cookin’ for Osaki Point over the next couple of weeks.

Right now, the wait is on. There’s no real surf to get excited about for the first couple of days. Sunday the 2nd sees a small, clean wave but it’s more of a paddle-around than a proper session. The real story is what’s brewing for later in the week.

The standout run kicks off from Tuesday the 5th and runs straight through to Friday the 8th. This is where things get wild. We’re talking about a massive pulse of groundswell, with a very long period of 16 to 18 seconds, pouring in from the ESE and SE. The combined energy is absolutely staggering, hitting values of 12,994 to 34,829 — that’s some serious power. Swell heights ramp up from 16ft to a ludicrous 25ft. This is expert-only, big-wave territory. The wind is onshore for most of it, but the sheer size and energy will make for an incredible spectacle. If you’re a seasoned charger with the right equipment, Wednesday the 5th afternoon and Thursday the 6th are the peak, with the biggest, most powerful surf of the whole forecast. For the average punter, it’s way too big, and honestly, it’ll be more of a tow-in or even a kite-surfing show.

After that massive episode, the swell drops back, but conditions get worse before they get better. From Saturday the 8th through to Tuesday the 11th, strong onshore winds and messy, lumpy seas make for poor quality. The water temp is a touch warmer than normal at 85°, which is nice for sitting out there, but you won’t want to be sitting out there in that junk.

Then, the real hidden gem arrives. Wednesday the 12th and Thursday the 13th are the best on offer for a normal surfer. The swell drops to a very manageable 8ft to 6ft, coming from the SSW with a solid 12-second period. The wind goes glassy and cross-offshore. This is clean, lined-up surf with moderate energy (1,048 to 1,892). This is the window for a quality session without the life-threatening size. Friday the 14th holds clean, smaller waves too.

After that, the last few days from the 15th onwards look poor again with onshore winds and weak, short-period swell.

So, to wrap it up: The clear standout for big-wave adrenaline is Wednesday the 5th and Thursday the 6th — huge, dangerous, and for experts only. The standout for a clean, fun, and surfable session is Wednesday the 12th and Thursday the 13th. Don’t sleep on that second window.

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.
