The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for the next couple of weeks.
We're kicking off with a bit of a flat spell. The first week from Sunday the 19th through to the 26th of July is pretty lean. Most days are offering tiny, weak waves around 1 ft to 2 ft with very low energy. The wind is mostly light and cross-off, but there just isn't enough push to get excited about. There's a glassy patch on Wednesday the 22nd morning and Thursday the 23rd morning, but with only 1 ft to 1 ft on offer, it’s more of a paddle than a surf. It’s a long, quiet stretch.
Now, here's where it gets interesting. Things start to wake up around Monday the 27th of July. The morning builds to 4 ft from the SSE at 12 seconds, but it's a bit onshore. The real standout is the afternoon of that same day, with a solid 6 ft southerly swell at 14 seconds. The wind is light cross-shore, so it’s worth a look.
But the main event is clearly Tuesday the 28th of July through to Wednesday the 29th. This is the pick of the entire forecast. Osaki Point is waking up with a solid 8 ft to 8 ft South to SSW groundswell. The period is 15 seconds on the Tuesday, dropping to 14 seconds on Wednesday, which is a proper long-period groundswell full of energy. The swell is packing a massive punch. The wind is the key: Tuesday morning is clean offshore from the SW, and Wednesday morning turns glassy. For a break that's a beach and reef setup, that long-period swell is going to be a dream, offering well-shaped, powerful lines. The water temperature is 83°F, which is about 2°F warmer than usual for this time of year, so it's a touch toastier than normal. This is for experienced surfers only—8 ft groundswell is serious.
After that, the window slams shut. From Thursday the 30th of July onwards, a strong onshore flow from the east and southeast takes over, with winds gusting up to 31 mph and rain. The swell stays big, 5 ft to 10 ft, but with lumpy, messy, onshore conditions, it’s more of a kite session than a clean surf. That run of poor conditions stretches all the way through to the end of the forecast on Monday the 3rd of August.
So, keep your eyes on Tuesday the 28th and Wednesday the 29th of July. That's the window. Get on it before the wind turns it to junk.
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.
