The Lowdown

Alright, let’s get into it. This is Rusty, and I’m looking at the next couple of weeks for Osaki Point. It’s a beach and reef setup, and it’s a consistent spot that handles a swell from the SSE.

Right now, we’re in a quiet patch. The first few days are pretty flat and not worth paddling out for. Saturday the 18th has tiny 2ft waves from the east, but the wind is messy and the energy is weak (61). The surf is poor. Sunday the 19th morning is glassy with that same small 2ft east swell, so you could get a few knee-high runners if you’re desperate, but it’s ordinary. The energy is only 59. That theme continues through Monday and Tuesday – small waves, 1ft to 2ft, with some clean windows but nothing to get excited about. The combined energy stays under 100, so it’s weak.

There’s a gap of several days of nothing special. Then, on Thursday the 24th, we get a little pulse. The morning is glassy with a 1ft swell from the SE, but the period jumps to 18 seconds. That’s a long-period groundswell, and the energy climbs to 93. It’s still small, but that long period means better shape. The wind is glassy, so it’s clean. Friday the 25th morning is also glassy, with a 1ft SE swell, 16-second period, and the energy is now moderate at 163. That’s a step up.

The real standout, though, is Sunday the 27th. The morning has a 3ft SE swell with a 14-second period, and the energy is 326. But it’s the afternoon that cracks it open: a 6ft SE swell, 13-second period, and the energy jumps to 1067. That’s strong wave energy. The wind is light cross-shore, creating small ripples, but it’s manageable. For a point break, a long-period SE swell is a good match, and the size is solid for intermediate surfers. This is the best session on offer.

Monday the 28th gets bigger: 8ft in the morning and 10ft in the afternoon, both from the SE. The energy is through the roof – 2054 and 2888. That’s some serious power. However, the wind is onshore or cross-onshore, and there’s a risk of thunderstorms. The waves will be big and powerful, but the wind will mess them up. This is more for experts only, and even then, it’s not going to be pretty.

Tuesday the 29th is huge: 12ft from the SSE, with a 14-15 second period, and energy readings of 3975 and 5851. The wind is a problem again – cross-onshore and choppy. This is a beast of a swell, but the conditions are going to be lumpy. It’s a pass for most.

From Wednesday the 30th onward, it’s a write-off. The swell is 15ft and bigger, but the wind is onshore and strong – 25 to 55 km/h. The energy is astronomical (8509 to 13230), but the surf is just a mess of blown-out, dangerous waves. Even the 13ft on Sunday the 2nd with a cross-off wind is blown out by a 60 km/h near gale. This is not a paddle situation; this setup looks more interesting for kite surfing than paddle surfing.

So, to wrap it up: the first week is a snooze, the best window is the afternoon of Sunday the 27th with that 6ft SE swell and cleanish conditions, and the big stuff later in the week is too windy and dangerous. The water temperature is about average for the time of year here.

Rusty, signing off.

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.
