The Lowdown
Alright, Rusty here. First off, we’ve got a slow start, but the back half of this run is gonna be a proper beast. The water’s about 84°F at Osaki Point, which is a touch warmer than usual for this time of year.
The first surf worth paddling out for is on Monday 27 July at Osaki Point (beach and reef). You’ve got a clean 2ft south swell at 9 seconds, with a light cross-off wind from the south. The combined energy is moderate at 214. It’s small but clean.
Tuesday 28 July stays small, with a 2ft south swell in the morning and a bit of ESE swell in the afternoon, both clean with offshore winds. The energy is light, around 129 to 130. Not much push, but you can get wet.
Wednesday 29 July and Thursday 30 July are similar – tiny swells around 1ft to 2ft, clean early, but fading. The energy drops to 102 and then 52 on Thursday morning, which is glassy but barely breaking. By Thursday afternoon, it’s cross-onshore and poor. Friday 31 July through Sunday 2 August is mostly flat with poor conditions and energy as low as 29. There’s a glassy moment on Sunday morning with a 1.0ft, 17-second groundswell, but the energy is only 126 – a long wait for a tiny wave.
From Monday 3 August, things start to change. The swell jumps to 5ft from the ESE at 15 seconds, with moderate energy at 888, but the wind is onshore from the ENE. It’s a bit messy. Tuesday 4 August pushes up to 8ft in the morning and 8ft in the afternoon, both from the ESE at 17-18 seconds, with strong energy climbing to 3163 and 4342. The wind is still light cross-onshore, so it’s a bit lumpy, but for experienced surfers, there’s serious power.
The standout for the whole run is Wednesday 5 August through Friday 7 August. Wednesday morning sees an 12ft ESE swell at 17 seconds, with energy at 6346, and only a light cross-onshore breeze. The swell is over 8ft, so this is experts-only. By Wednesday afternoon, it’s 12ft at 18 seconds, energy 7716. Thursday 6 August ramps up to 15ft and then 16ft with 18-second periods – the energy hits 12538 and 15456 – but the comment says it’s actually too big for this break. Friday 7 August is even bigger, with 25ft and 26ft swells, energy in the tens of thousands, but again, too big. The wind is onshore or cross-onshore, so it’s not clean, and honestly, this setup looks more interesting for kite surfing than paddle surfing.
The real highlight for the best on offer, if you’re an expert, is Monday 10 August. The swell drops to 16ft from the SSW at 13 seconds, with a gentle cross-off wind from the west, and the energy is still strong at 11387. Conditions are described as exceptional for expert surfers. The water is clean, and the wind is light. Tuesday 11 August will still be solid, with a 5ft east swell in the morning, clean and cross-off, excellent for experienced surfers, but it’s a step down from the Monday.
Overall, the first week is a quiet one, with a blank run from 31 July to 2 August where there’s really nothing doing. The second week brings serious size, but it’s too big for most, and the real sweet spot is Monday 10 August.
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.
