Asakawa Surf Forecast and Surf Report

Alright, grab your board and listen up. It’s Rusty here, and I’ve had a good look at what’s coming our way for the next couple of weeks. Honestly, the start is pretty flat, but once the ocean wakes up, there’s a serious pulse of swell on the horizon.

Right now, we’re stuck in a bit of a lull. The first real chance for a wave at Asakawa is on Monday the 15th, but it’s only 4 ft of SE swell with a 9-second period. The energy is moderate at best (260), and the water temp is sitting at 82°F, which is about average for this time of year. The wind goes glassy in the morning, which is a major positive and will keep it clean, but it’s not going to get the heart racing – it’s more of a grovel session.

We have to sit tight through the middle of the week. There are bits and pieces of small, weak swell with cross-off winds, but nothing worth paddling out for in earnest. Thursday the 17th is a write-off with clear skies but barely a ripple to ride.

Then, hold onto your leash. Friday the 18th morning sees a jump to 7 ft of E swell with a 9-second period and the wave energy ramps up to a punchy 828 (moderate to strong). The wind is a light cross-off from the NE, keeping things clean. This is the first real standout. For Asakawa, being a point break, this could shape up nicely, though the period is a bit short for a proper groundswell.

But the big news starts Saturday the 19th. This is where the ocean starts flexing its muscles. By the morning, we’re looking at 10 ft of ESE swell, and the period jumps to a very long 14 seconds. The combined energy is huge—3442 (strong). The wind is a cross-off from the NNE, so the surf will be clean and powerful. This is for experienced surfers only; over 8 ft it’s expert territory. The sets will be super long and clean, perfect for the point at Asakawa.

Sunday the 20th pushes even bigger, with 12 ft to 13 ft SE swell, still holding that long 14-second period. Energy is through the roof (5582 on Sunday morning). Winds are still cross-off from the NNE, so conditions will be very good, but this is massive. Monday the 21st is the peak of the run, with 15 ft to 16 ft SSE swell and a 15-second period. Energy hits 9780 – that’s serious ocean power. Again, cross-off winds from the NNE mean the surface should be reasonably clean for how big it is. Tuesday the 22nd goes completely nuts with 18 ft swell early, but then a gale-force wind hits 40 mph from the NNE, making it unsurfable and dangerous. By the afternoon, an offshore gale from the NNW shows 43 mph winds with a 10 ft swell – it’s a full-on storm warning. Don’t even think about it.

After that monster week, the ocean needs a nap. From Wednesday the 23rd onward, we’re back to small, weak swell, mostly under 3 ft, with light to moderate winds. There are a few glassy moments on the 25th and 26th with small 3 ft SE swells, but the energy is low (178 to 226). It’s a long, quiet finish to the 16-day window.

The standout call: Saturday the 19th through Monday the 21st. If you’re an experienced surfer, this is worth a trip. The combination of long-period groundswell, clean cross-off winds, and serious energy is about as good as it gets at Asakawa. Just be ready for a paddling workout and a lot of water moving around. Beginners should stay on the beach those days and just watch.

Rusty.
