Asakawa Surf Forecast and Surf Report

Alright, Rusty here. Let’s talk about what’s cooking at Asakawa.

We’ve got a bit of a slow start, but the second week is where it really gets interesting. The water is sitting at 83°, which is about average for this time of year, nothing unusual there.

The first few days are pretty flat and forgettable. Friday and Saturday mornings will see tiny, knee-high waves around 3 ft to 3 ft from the S/SSW. It’s glassy early, which is nice, but there’s just no energy – the combined swell energy is only 175, so it’s weak. Not worth paddling for.

Sunday morning stays small at 2 ft, and the period drops to 8 seconds, making it weak and crumbly. Then we hit a real lull. From Sunday afternoon right through to the end of the month, there’s nothing that gets a strong recommendation. The conditions go downhill with cross-onshore winds and building storms. There’s a gap of about 3 or 4 days where the surf just isn’t good enough to recommend.

Now, things start to shift on Monday the 24th of August. That morning brings a standout window. The swell jumps to 5 ft from the SE with a 19-second period – that’s very long period groundswell. The combined energy is 1735 (moderate to strong) and it’s glassy. For a point break like Asakawa, that long period is perfect, meaning well-shaped, clean lines. It’s a spot that’s inconsistent, so when it fires like this, it’s special. It’s intermediate-friendly at this size, too. The afternoon gets bigger – 8 ft – but the wind shifts onshore, and it gets stormy, so that morning is the pick.

The next few days see huge swell, but it’s messy. Tuesday the 25th shows 13 ft from the SSE with period around 16 seconds. That’s expert-only territory. The combined energy is 6858 – very strong – but the wind is cross-onshore and there’s a risk of thunderstorms. It’s more of a serious, big-wave mission than a fun session. Wednesday the 26th and Thursday the 27th stay big and messy, with onshore winds and energy still high. Friday the 28th drops back to 6 ft to 6 ft, but with short 8-second period and onshore wind, it’s still not great.

Looking further out, there’s another real standout. On the 3rd of September, we see excellent conditions. The swell is 7 ft to 7 ft from the E/ESE, with periods between 14 and 17 seconds. The combined swell energy is over 2000, and the wind is cross-offshore out of the NE at 9 mph – clean, crisp, and lined up. This is a long-period groundswell hitting the point just right. The morning of the 3rd is the real gem, with the afternoon and the 4th also offering excellent surf at around 7 ft. This is the best on offer for the entire outlook. By the 5th, it fades back to small and weaker options.

So overall, keep an eye on Monday morning the 24th of August and the 3rd to 4th of September for the true standouts. The rest of the time is either small, messy, or too big for comfortable surfing.
