The Lowdown
Alright, let me break this down for you. The next couple of weeks at Osaki Point start off real slow, but there's a solid pulse of swell coming in the first week of August that's worth waiting for.
For the first several days, starting Wednesday, July 22nd, we're looking at tiny surf. Waves are only about 1ft coming from the east. The water is running a touch warmer than usual at 83°. Light offshore winds in the morning will keep it looking clean, but there's just no power behind it, with a combined energy reading of just 50. Thursday and Friday stay small, dropping to around 1ft. Thursday morning is glassy, which is nice for a paddle, but you won't be riding much. This pattern of small, clean, but weak surf holds through the end of July. The energy stays in the weak to moderate range, and you'll be struggling to find a wave with any real punch.
The first real change comes around Thursday, July 30th. The swell picks up to about 2ft to 3ft from the south-southwest. Morning sessions look glassy, which is a huge plus, and the energy is climbing into the moderate range, around 108 to 119. Friday the 31st keeps those 2ft waves in the morning with glassy conditions, and the afternoon sees a big spike in energy to 310, coming from a long-period easterly swell of 18 seconds.
Now, the window you've been waiting for is the first weekend of August. Saturday, August 1st, the swell jumps to a solid 4ft in the morning, building to 5ft in the afternoon, from the east with a very long period of 16 to 17 seconds. The morning is glassy, so expect clean, lined-up waves. The energy jumps to 844 in the morning and over 1200 in the afternoon. This is the pick of the run for intermediate surfers.
Sunday, August 2nd, is the big one. Swell is 6ft in the morning, peaking at 7ft in the afternoon, with 18-second periods from the east. That's a serious, powerful groundswell. The morning is glassy, and the wave energy is massive – 2342 in the morning and over 3120 in the afternoon. This is expert-only territory. Anything over 8ft is getting dangerous, and this is right up there. That long period will make for some powerful, but maybe a little straighter, waves at a beach break.
Monday the 3rd and Tuesday the 4th keep the size up, with waves around 7ft to 8ft and very strong energy. Winds look a bit more onshore on Monday, but Tuesday morning is glassy again. This entire stretch from the 1st through the 6th of August is where the surf is. The energy starts to drop on the 5th, with 4ft waves and glassy conditions, but it's still miles better than the opening week.
So here’s the call: the first week is barely worth a look. Save your energy. The real action kicks off on Saturday, August 1st. Sunday the 2nd has the most size and power, but it's strictly for the pros. For the best balance of good waves, clean conditions, and manageable size, I'm pointing at Saturday, August 1st. Get out there.

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.
