The Lowdown
Alright, this is Rusty here. Let’s have a look at what’s headed our way over the next couple of weeks at Osaki Point.
First up, don’t even bother paddling out this Friday the 31st of July. There’s a tiny 1ft swell from the SE, and while the morning looks glassy, the wave energy is weak (50). It’s just not worth it. The afternoon gets a bit choppy with a cross-shore wind, so give it a miss. Saturday the 1st of August is similar – small, weak, and poor conditions all day. Sunday the 2nd is where things start to turn. We get a clean glassy morning with a 2ft ESE swell, but the energy is already building (401). The afternoon on Sunday is the real standout for the first week: 4ft of ESE groundswell, period of 16 seconds, glassy conditions, and a strong combined energy of 690. That’s a proper long-period groundswell, so expect clean, lined-up waves with long waits between sets. Perfect for a point break or reef setup like this.
Now, Monday the 3rd and Tuesday the 4th see a big jump in size, but the wind gets messy. Monday morning is 5ft with onshore wind, and by Tuesday we’re looking at 11ft to 13ft, with energy readings in the thousands (7020 and 9830). That’s a serious amount of water moving, but the onshore and cross-onshore winds will chop it up. Not ideal for a fun session.
Wednesday the 5th and Thursday the 6th are for the big-wave chargers only. We’re talking 18ft to 28ft of SE swell with massive energy (over 19,000). The wind is onshore though, and the commentary says it’s too big for this break. If you’re an expert and you know the place, maybe, but for most of us, this is a skip. Friday the 7th drops back to 11ft-13ft, but the wind is still messy and the conditions are poor.
The second week gets more interesting. Starting Sunday the 9th of August, there’s a lull with smaller 4ft swell and onshore wind. Not much to get excited about. But mark your calendar for Wednesday the 12th of August. That morning we get 5ft of SE swell with a clean offshore wind from the WSW. The energy is solid (1264) and the conditions are described as excellent for experienced surfers. The swell direction (SE) lines up well with the optimum for this spot (SSE). Glassy, clean, and good shape – this is the one to aim for. The afternoon holds similar with 6ft and light offshore breeze. Crowds can be an issue here sometimes, but on a Wednesday it might be worth the gamble.
Thursday the 13th also looks promising with a 4ft S swell and clean cross-offshore wind in the afternoon. Friday the 14th finishes the period with a glassy afternoon and 4ft from the S – a nice mellow end to the run.
The standout is without doubt Wednesday the 12th of August. That offshore wind, decent size, and proper energy make it the best on offer. Sunday the 2nd of August afternoon is a close runner-up for the first week if you want cleaner waves before the big stuff hits.
Stay safe out there.
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.
Osaki Point is 14 km (9 miles) from Muroto. If you plan a holiday in Shikoku, look for hotels and other accommodation in Muroto. Muroto has rooms for a wide range of budgets as well as car hire and transport links.
